Branding By Numbers: Making A Case For Colour KPIs

By Paul Haggett, Business Development Manager, Schawk

In the production of graphics for branded materials, whether it’s printed packaging, a label or even something as simple as a shipper, errors and inefficiencies always have root causes.

As in many other areas of business management, key performance indicators (KPIs) are great at helping us locate and identify the root causes of errors and inefficiencies, and provide us with the facts needed to correct them.

KPIs can also go further to foster collaborative dialogue and analysis amongst all stakeholders in the graphics supply chain, be they designers, production agencies, print vendors and of course brand owners themselves.

Ask the right questions.
When it comes to the production of branded materials, the key questions are what are the right KPIs and how can we implement and act on them? Surprisingly, many stakeholders in the graphic supply chain are not clear on these answers.

Set benchmarks.
As is the case with many things in business and in life, the old adage, “If you can’t measure it, you can’t manage it,” applies here. So the first step is agreeing to a set of relevant benchmarks to measure against. When it comes to branded materials, outside of the actual packaging material or substrate, you can measure two crucial elements: content and colour.

Establishing KPIs for colour:
Defining KPIs for the capture and use of content, the actual pack copy and regulatory data itself, is a task for another article. Here we are going to concentrate on how setting KPIs for colour can deliver significant benefits to all stakeholders in the graphics supply chain – in particular the brand owner.

From the outset, it is crucial there is collaboration between all those involved. Arbitrary setting of colour KPIs by a design agency or a graphic production/pre-press agency will only cause angst for a printer. Likewise, applying colour KPIs defined by a gravure printer who prints on gloss while films to a litho printer whose common substrate is recycled board will be a waste of time.

The point here, is that engaging the relevant stakeholders at the outset helps to set realistic expectations for all concerned. Benchmarks are established, and if required, boundaries can be pushed.

A collaborative graphic production partner who can coordinate with all relevant print suppliers and the chosen creative agency can best achieve this task. Visibility of the entire project and accountability through defined KPIs ensures a consistent outcome of all branded materials, regardless of the printer’s geographic location. With sufficient preparation, costly and time-consuming press passes can be a thing of the past.

That’s where platforms like ColorDrive come in. With ColorDrive, the industry’s first and only supply chain-focused, cloud-based print quality management platform, stakeholders can monitor print quality parameters globally, in real time, and make calls on colour adjustments with greater confidence.

Strengthen Brand Equity Through Transparent Label Communications


By Bruce Levinson
Vice President, Client Engagement, SGK


The need for clarity is driving current EU and pending U.S. FDA regulations for more detailed and prominent label nutrition information. Clarity will help ensure that food is safe and make recalls – when they happen – faster and more effective. But perhaps even more important, more detailed and readable labels will help consumers make more informed decisions about products they buy and use. And this is just part of a bigger story about the consumer/brand relationship.

Consumers today are putting unprecedented pressure on brands and manufacturers through their ability to collect, compare and demand information, especially about the foods they eat. Brands and manufacturers must embrace this to sustain their own businesses. Smart companies are already reconsidering their own labeling philosophies and communications habits to better address consumer desire for honest and clear nutrition information – in advance of the pending government regulations.

Even before the current focus on label information, certain food categories had cultivated information-based relationships with their customers that show the inherent power of clarity.

Coffee is a perfect example. It’s not just the vast choices available to-go or for home brewing. Thanks to extensive information at coffee shops, on packages and online, we can develop and cultivate our own tastes. We can scrutinize caffeine content or country of origin, whether the bean is organically grown or ethically sourced. Starbucks has built its reputation on making the consumer a partner in this information. It does an excellent job of delivering the same “information experience” in every shopper context – and it now has more than 37 million “likes” on Facebook.

You could call this the “gourmet-ification” of food and beverages – in which categories that had a strong commodity component become more nuanced, differentiated and profitable. We’ve seen similar trends in beer, juice, water and yogurt. But it goes further than the taste and cachet. Consumers are now deeply informed on health. For example, gluten-free was a concern of a relatively small group of people ten years ago. Today, information on the subject is abundant, and the U.S. market for gluten-free food was estimated as high as $10.5 billion in 2013, reaching $15.6 billion in 2016.[i]

In the same vein, marketers can expect consumers to grow more aware that “Made With Whole Grains” is not the same as “100% Whole Wheat.” And you can expect more shoppers to buy not just on the basis of what isn’t in a product (looking for “0%” on the nutrition label) but of what IS in the product. In this regard a number of recent brands of natural juices and granola bars are simply stating their ingredients – often a list of a few whole foods we all recognize – in plain view and in stark contrast to processed brands.

The lesson is that successful brands are “out in front of” evolving government regulations, not looking for ways to skirt or challenge them. Early in 2014, a U.S. Supreme Court ruling in a case involving a major global beverage manufacturer made it clear: even though a product meets FDA regulations for categorization, it can still be held as misleading consumers.

And the court of consumer opinion can dish out even harsher sentences, because they involve earning back trust. So the implication is clear: government regulations are, in some ways, the low bar – not the high bar – for accuracy and legality.

But by the same token, regulations don’t represent or create a demand where it doesn’t exist. It’s possible to be out in front of regulations but also too far out in front of consumer interest and demand.

For example, in the 1990s, numerous state governments set emission standards in a way that would encourage electric cars. But it wasn’t until Toyota made the Prius, fifteen years later, that a critical mass of consumers meshed with a product they could really embrace.

Prius has had commercial success not because the government said it would, but because Toyota built something that catered effectively to a need. And Tesla is perhaps an even more relevant example today. It’s the fastest growing car company in the world.

The examples offered all point to some important truths: The public and their governments are paying more attention to labels, and governments are becoming more regulatory where consumer products are concerned. But wise brands don’t mistake regulations for marketing plans or messaging strategies. Instead, regulations are merely a springboard toward clarity, transparency and a more profitable relationship for both the consumer and the brand.

Dr. John Writes: A Blast from the Past – Flexo Print Fault Guides from the ’90s



During a recent ‘de-clutter’ session at home I came across my 1998 box of materials from the EFTA in England, and took a quick trip down memory lane with a printed copy of the “Typical Flexo Print Faults” guide from Sun Chemical. As I thumbed through it I was amazed at just how BAD the issues looked when viewed through ‘today’s eyes’. I know the guide contained truly bad cases for each defect to make sure the fault was visible, but to some degree these really were daily occurrences back then. It struck me how few of these we see today, and if we do see them, how they are never present to that degree.

The list of “Typical” Flexo Print Faults In 1998 included:

  1. Poor Trap
  2. Ink Smearing / Dot Bridging
  3. Dirty Print / Fill In
  4. Mottled Print
  5. Print Striations
  6. Uneven Colors
  7. Poor Ink Coverage
  8. Pinholes or Fisheyes
  9. Washboard Print
  10. Dark or Dirty Print Color
  11. Ink Foaming
  12. Weak Print Color
  13. Inconsistent Print Color
  14. Dirty Print / Halos
  15. Dirty Print / Feathering

 What’s with all the Dirty Print?

Did you notice that 5 of the 15 print faults involved the words “Dirty Print”, and several of the others could easily be considered in that type of category? It’s sometimes easy to forget that only 15 or so years ago Flexo had a LOT of issues, struggling with lower quality and a highly inconsistent process.

What is also interesting is that the primary causes of these print faults were not due to a single factor; they were due to issues with the ink, anilox, ink supply, plate, doctor blade, operator, substrate, tape and press combined. The improvements that have been made since that time, and that give us the flexo performance we enjoy today, have truly been across the board – though it’s true to say that they don’t always happen in perfect synchronization.

When one supplier comes up with the latest major advance, it often takes time to completely step the industry forward, because no one component is independent of all the others. As an example, and one that’s close to my heart, when new significant improvements in plate capabilities are introduced, they are supported in implementation over the following years by continuous improvements in the ink, anilox, tapes and the press, until they all come together to unlock the true capabilities of the plate – and vice versa.

The Supermarket Test

It used to be that you could walk down the middle of any supermarket aisle, and a wide one at that, and you could spot the flexo printed products on the shelf from 5 feet away. The typical Flexo halo was often the first giveaway, but now that is very much the exception, and you need to get a lot closer than 5 feet to see it!

As an industry we should be PROUD of what we have done, as suppliers, printers, and service providers, we are now as good, and on most days better than the other print processes that we could only dream of matching back in 1998, on a wider range of inks and substrates than ever before. It’s why we mustn’t stop collectively educating our end users, especially those ones that have long memories, about the capabilities of 21st century flexo.

We’ve come a long way in the last 15-20 years – but it’s important to not become complacent and accept that even the Flexo we are printing today is “good enough”. There is always room for improvement and I know that I, for one, will not stop trying.  J

OK, back to those boxes…

Anilox Roll Cleaning Essential to Effective Ink Delivery


by Flexo Concepts

Anilox_Cleaner_300X298You spend plenty of time selecting the correct anilox roll for a job. Careful consideration goes into line screen, cell geometry and cell volume in order to guarantee that a precise amount of ink or coating is delivered to the substrate. Aniox roll cleaning is essential to maintain this precision. If you neglect to clean your rolls on a regular basis, you will not get the most out of your anilox investment. Plugged cells will affect print quality and cause you frustration, waste and downtime. An anilox cleaning program consisting of daily, weekly and deep cleaning will preserve the integrity of the anilox engraving and ensure quality, press efficiency and longer anilox life.

When a newly engraved anilox roll arrives from the manufacturer, volume is even across and around the surface of the roll. As the roll is used, however, a residual amount of ink or coating material is left behind in the cells after the transfer has taken place. The residue dries and creates build-up in the cells.  Over time, these deposits decrease the capacity of the cells and reduce their ability to carry and release the volume of ink or coating for which they were designed. This residue also raises the surface tension, or dyne level, of the roll and increases the tendency of the coating to “cling” to the surface. When this occurs, the roll will not release the proper volume or ink or coating to the plate.

Benefits of regular anilox roll cleaning:

  • The repeated transfer of a precise volume of ink or coating
  • Consistent coverage
  • Reduced labor and less downtime
  • Fewer job rejections and waste
  • Longer anilox life and lower re-working costs

Flexo Concepts recommends a 3-step anilox roll cleaning program:

1. Daily wiping to prevent ink or coating build-up
Applying a liquid cleaning agent by hand and wiping down the roll with a clean, lint-free cloth on a daily basis is the simplest and most effective way to prevent keep ink and coating from drying and building up in the cells. As a basic rule of thumb, the best time to clean a roll is as soon as it is removed from the press. The longer inks, resins, adhesives, etc. have been allowed to sit in the engraving, the harder these materials are to remove. To maximize cleaning performance, choose a cleaner specifically formulated to remove water-based, UV or solvent-based chemistries based on your application.

2. Weekly scrubbing with a paste-like cleaner and an anilox cleaning brush
Manually scrubbing the roll once or twice a week with a brush and a paste or cream chemical cleaner will mechanically loosen and remove any ink or coating residue that remain in cells despite daily cleaning. The cleaner is applied to the roll, vigorously scrubbed in a circular motion with an anilox cleaning brush and flushed with water while the roll remains in the press. It is important to remember that stainless steel brushes are suitable only for ceramic anilox surfaces and brass bristles should be used for chrome surfaces to prevent damage to the engraving.

3. Monthly deep cleaning to remove tough ink or coating deposits
Over time a residual amount of ink or coating material is left behind in the cells and the roll requires a deep cleaning to remove these tough deposits. The most common methods of deep cleaning are chemical wash and ultrasonic. The roll is removed from the press and placed into a chemical bath where it soaks in a powerful cleaning solution before being subjected to a high pressure rinse or ultrasonic vibrations to loosen and dissolve the deposits. These methods vary in cleaning effectiveness, risk of damage to the roll, and water and chemical consumption.

Like on other parts of the press, a maintenance program for anilox rolls keeps the ink delivery system running at its peak. Regular anilox roll cleaning will prevent anilox cells from plugging with ink and coating residue and stop build-up before it dries. Maintaining anilox rolls through a regular cleaning program can pay off tremendously in terms of maximizing print quality, press efficiency and cost control.

Viscosity & pH Control: Increasing Productivity Through Automation


Paul Lancelle, Technical Solutions Group, All Printing Resources, Inc.

Ongoing control of ink viscosity remains as, arguably, the most significant variable in the flexographic reproduction process. If it is not controlled continuously and closely, uniform ink coverage and accurate color match cannot be achieved. Given the costs of solvent and water-based inks, printing operations of any size can save significant costs by controlling ink viscosity.

A good incentive for increasing your understanding of viscosity is to keep in mind that improper viscosity can cost money: a shift of one second on a #2 Zahn Cup can result in 50% excess ink laydown. Improper or high and low “spikes” in ink viscosity also result in ongoing color management issues, as this same one second shift can result in a change in color measuring dE 2 or greater. Viscosity affects not only the hue and strength of the printed color, but impacts other print quality attributes including ink lay, dot gain and trapping. Additionally, performance properties such as coating weight, drying speed and solvent retention are all affected by ink viscosity.

For water-based ink applications, equally important is the ongoing monitoring of pH, due to the interrelationship that exists between pH and viscosity control. Water based inks rely on precise pH control to maintain resin solubility and stability. While manual monitoring remains the “least expensive” means of monitoring pH and viscosity throughout a print run, it is quite common for these methods to quickly turn into a “tail chasing the dog” scenario due to several difficult to control factors:

  • Inconsistent measurement practices between operators
  • Accuracy of efflux cup
  • Irregular timing between monitor checks
  • Disruptive solvent/amine mix “shock” (too much at once)
  • Pigment differences between inks
  • Varying solvent/amine evaporation points

Whether running water or solvent based ink systems, checking ink manually with a stop watch and measuring cup or automatically with an unreliable mechanical system simply does not meet the demands of today’s packaging buyer in terms of color consistency within a job and from one run to the next.

Of equal significance lies the point of ink temperature control. Temperature is a critical parameter in the printing process, and is very often underestimated. Ink temperature is affected not only by ambient environmental conditions, but by press speed and run length, as well. With the ongoing trend toward higher press speeds, ink temperature control has warranted a greater focus. As ink temperature rises, viscosity drops and evaporation rates increase, resulting in another critical balance point. By controlling the ink temperatures, significant ink and solvent savings can be realized and color stability will improve, as well.

Automated control systems were developed to overcome shortcomings and limitations of manually measuring viscosity and pH. Although automated systems have been available for many years, a better understanding of ink, the printing process and the influence of viscosity and pH on print quality have resulted in improved and more reliable systems. Most new presses sold today, particularly in the wide and mid-web segments, come equipped with varying types of advanced automated viscosity, pH and temperature control systems. It is of common industry agreement that ink viscosity should not vary by more than +/- 5% throughout a run… a standard that is difficult to achieve with manual measurement practices. Most of today’s automated systems feature even tighter tolerances than that. The benefits realized by the printing operation are numerous, but primarily include:

  • Ink and solvent savings-often estimated between 25-60%
  • Print quality and consistency through consistent color reproduction
  • Ink quality is maintained throughout a run
  • Maximized press operating speeds
  • Minimized waste
  • A permanent record for quality control purposes

For these reasons, it is well worth the consideration and investment in retrofitting older model presses with automated control systems. Print managers must select a viscometer/pH control system based on their production needs, and this is dependent upon numerous factors, including operator acceptance, consistent measurement and control, fit with existing equipment, expected cost savings, and maintenance and repair.

FIGURE A “Falling Body” Inline viscometers

“Falling Body” Inline viscometers

The traditional and prevalently common method of automated viscosity control in the printing industry has been with “falling body” technology. The basic concept is to measure the elapsed time required for a ball to fall, under gravity, through a sample-filled tube. The measurement is taken periodically and is not a continuous measurement. See Figure A.

More recently, the flexo print industry has been moving more towards the adoption of “vibrating rod” technology, which consists of a straight metal rod maintained in resonant vibration by a continuously applied power source. Installed in-line to the fluid flow, the sensor is between the ink pump and printing deck. Using the integrated computer, the viscometer emits sound waves in the ink-much like a musical “tuning fork. “A detection circuit then analyzes the changes in these waves caused by the tiniest of

FIGURE B VISCOWAVE Vibrating Rod in-line viscometer

variations in the ink viscosity. See Figure B.

The advantages demonstrated with “vibrating rod” technology, particularly when choosing the VISCOWAVE technology offered by New Celio Engineering, are multiple when compared to “falling body” methods. Demonstrated improvements can be seen from:

  • High accuracy rate
  • No moving parts=cleaning not required
  • Easy in-line installation
  • No maintenance
  • No wearing parts
  • Compact and lightweight
  • Full stainless steel construction

In addition, the VISCOWAVE comes with built-in temperature measurement and has options for controlling ink temperature to provide a “complete package” toward automated ink control.

Consideration of the added benefits recognized from the higher accuracy and dependability combined with reduced maintenance and cleaning may lead to printers with previously installed versions of automated viscosity control systems recognizing a significant ROI when upgrading to these newer technologies. The same concept holds true for automated pH control, as earlier systems were often found to be challenging to clean and maintain.

Polyester Containment Blades Win over Steel



Polyester_coil_knockout_300x135For such a seemingly insignificant part of the press, the containment blade’s job is an important one.  After all, it is a fundamental component of the doctor blade chamber.  By forming an enclosed system, the containment blade plays a key role in allowing the printer to maintain ink viscosity, minimize skimming, lower ink consumption and simplify cleanup.

In wide web applications, choosing polyester containment blades over steel is a smart way to save money, improve safety and reduce your environmental impact.  Unlike the metering blade, which has a direct impact on print quality, the containment blade only has to contain ink in the chamber.  This gives a printer more options to choose from with regard to blade materials.  Learn why polyester is a superior choice over steel.

Top 5 reasons to switch to polyester containment blades:

  1. Trail doctoring – Some printers experience trail doctoring at higher press speeds when using steel containment blades. Steel blades are too stiff to allow back-doctored ink to pass underneath the blade and back into the chamber.  Ink builds up on the back side of the blade, pools at the end of the chamber and eventually slings onto the press and web.  This situation not only creates a mess but also affects print quality.  Printers can eliminate trail doctoring by using polyester containment blades.  This material is equally effective at containing ink in the chamber but thin and flexible enough to let back-doctored ink return to the chamber.
  2. Cost – Polyester containment blades cost substantially less than steel blades. The price per inch for polyester typically ranges from one-third to one-half that of steel.
  3. Safety – By replacing one of the steel doctor blades in a chamber with polyester, you can reduce your risk of doctor blade injuries by 50%. Unlike steel, polyester blades are safer to handle than steel and won’t cut press operators when they are installing and removing them from the press.
  4. Environmental impact – During production, polyester blades emit a small percentage of carbon dioxide compared to steel blades. Using polyester containment blades can help printers meet requirements for reducing their carbon footprint.
  5. Anilox damage – Polyester containment blades will not score or damage anilox rolls. The material is soft and contains no sharp fragments which can break off, become lodged against the roll and destroy the engraving as the roll turns.  The material is non-abrasive and won’t cause excessive wear on the roll.  Replacing or re-engraving anilox rolls is expensive, so extending their life can be a huge cost savings.

Printers are always looking for ways to improve efficiency and save money.  Why not choose a containment blade that not only costs less but also has additional pressroom benefits?  Polyester containment blades offer a less expensive and safer alternative to steel that also reduces trail doctoring and environmental impact.  It’s amazing how such a small change can make such a big difference!

6 Ways to Get Your Branded Materials to Market Faster

sgk_logo_pmsBy Jesse Moen, Director, Continuous Improvement Practice, SGK

Getting packaging, promotional, digital, and other branded materials to market quickly can feel overwhelming.

As organizations grow, additional layers of approvers and stakeholders become involved in the supply chain, accountability becomes decentralized and ambiguous, and workflows do not evolve quickly enough to accommodate the larger scale of work required.

What should be a relatively straightforward process becomes bogged down in a complex and time-consuming web of competing agendas, obsolete policies, and siloed communications. For example, some Fortune 100 clients require a four-month lead-time for FSIs and a six-month (or more!) lead-time to redesign a package. While these may be outliers, they are representative of the types of problems many organizations face, and they prove that agility and responsiveness are critical to achieving topline growth.

To become more nimble, marketing organizations need to think “lean” and remove non-value-adding tasks from their branded material supply chains.

Here are six proven practices:

1. Validate your inputs. While this may be considered a no-brainer, most organizations struggle with input validation because it’s actually pretty hard. Design managers, production managers, and agency PMs are under enormous pressure from Brand and Sales to “just go.” Projects are kicked off without briefs, die lines, approved claims, or formulas. While this “fix-it-later” mentality may work anecdotally at the enterprise level, it drives multiple rounds of time-consuming revisions into both the creative and production processes. This habit is the primary root cause of design and production revisions. Strong discipline and leadership are required to break it.

Once this practice has been abandoned, it’s time to organize. Sit down with your agency/production partners to logically categorize all the inputs required to create/produce your materials. Choose a taxonomy that makes sense for your organization. Then organize the information into a standardized form. This can be as simple as a spreadsheet or as advanced as a database. If you go the database route, you can begin experimenting with linking the data directly to artwork.

The difference between organizations who do this well and those who struggle is striking. Organizations who have stringent validation procedures in their packaging workflows see upwards of 85 percent of all packaging changes approved within two cycles or fewer.

Organizations with poor validation procedures perform much worse, with only 60 percent of changes approved in two cycles or fewer. This 25-percentage-point difference can translate into thousands of hours of lost workforce capacity, weeks added to each project, and significant change fees from agencies and production partners.

2. Streamline your routing and approval process. Assuming you have a formal routing and approval process, dig in and question why so many people need to approve your packaging and promotional materials. The more people involved in approving work, the greater the drain on your organization and your marketplace agility.

Approvals are a hot-button issue within any content-rich organization. There are often competing internal agendas demanding involvement in approvals, but there is often just as much support for improving this process. To do so, look for opportunities to take people out of the approval cycle, to establish parallel path approvers, and to create simplified processes for simple deliverables.

Streamlining this process can make a significant impact on cycle times. For one CPG, the number of approvers required across all packaging and promotions routing and approval workflows was reduced by 67 percent. This equated to 4,000 hours of annual labor savings and reduced average routing cycle times by over a week.

3. Eliminate redundancies. Analyze the duties and tasks performed by your marketers, marketing communications staff, and agency/production partners. Look for redundancies in project management, approval processes, and meeting attendance. You’re apt to discover that many of the redundancies will be tactical tasks; while each task may only take a few minutes, adding them up annually over thousands of packaging changes, promotional materials, etc. amounts to a significant loss of time and energy.

For example, an analysis of the duties and tasks performed by junior marketers and marketing communications staff at one CPG revealed task redundancies in the initiation and management of packaging projects. Post implementation surveys revealed a 15 percent capacity increase within the junior marketer role once these redundancies were addressed. 

4. Focus resources and time on what’s most important. Evaluate your mix of marketing materials and decide which consumer touchpoints are critical to your growth. Then critically evaluate all workflows that support the less critical touchpoints. Media that are not delivering should require little to no attention from marketing leadership in a$1B+ organization. Relentlessly pursuing this philosophy will free up staff to execute more efficiently on high-value activities.

A major CPG did just this and removed all tasks related to design initiation, review, and approval processes for FSIs from their Marketing team. Across all divisions, this freed up a collective day and a half of weekly status, review, and kickoff meetings.

5. Go digital. Requesting and trafficking files on CDs and printouts is the antithesis of a “lean” process. They need to be shipped, stored, and managed, and they can’t be indexed for searching on your computer. An all-digital workflow empowers your organization, driving speed, efficiency, and accuracy throughout the enterprise—a velocity that can provide a competitive difference.

For example, a client had been requesting disks and three sets of printouts for all of their final artwork files. These assets were then stored and scattered across expensive office space in midtown Manhattan. After working through the perceived needs of the organization, we helped establish a workflow and file management strategy to completely eliminate all of the disks and printouts. Doing so saved the organization thousands of dollars in shipping/courier fees, cleared up valuable office space, and mitigated the need to organize and store thousands of files annually.

6. Remove communication roadblocks. It’s a common occurrence: agency and production partners are often frustrated by the excessive communication pass-throughs by clients and the red tape around information required to create their branded materials. But trusting your partners and enabling them to communicate deeper into your organization provides them with a roadmap for information. Empower them to initiate approval routes inside your online approval tool. If you have serious reservations about this, spend a few minutes evaluating your concerns to understand if they are related to control, partner ability, or something else. The idea is to remove obstacles and simplify for speed.

To that end, the solution could be as simple as assigning multiple points of contact based on areas of expertise within your organization. One consumer promotions agency was required by a CPG to leverage a single point of contact within the CPG’s brand design group to field all questions and requests. While this strategy was intended to ensure brand consistency across marketing media, it was inadvertently tripling the number of queues within the workflow for tactical requests. Eventually, the agency was provided key contacts within the CPG organization for tactical requests, such as die lines, bar codes, legal copy, and offer codes. This simple empowerment eliminated two workflow queues as well as the redundant communication management performed by the brand design manager and agency project manager.

The speed at which branded materials are created and deployed can drive increased sales, enable organizations to respond to quick-turn opportunities with key retail partners, and free up resources to put against growth objectives. The increased productivity that optimization offers can drive your brand’s performance by delivering it to market more quickly, more efficiently, and more cost effectively. The successful implementation of the strategies outlined above will help your organization cut non-value-added time and energy from your branded material supply chains and streamline your processes.

Are you experiencing Pin-holing and Production Pitfalls? – Part 2



In the previous Part I of this blog, I talked about the ink transfer process in flexographic printing and how it can introduce the problem knows as pin-holing. Over the years, manufacturers have tried to solve the problem in various ways with limited success. Likewise, flexo printers have tried to compensate for the pin-holes by applying more ink to the job, and more pressure on press, but that only drives up costs and introduces other complications.

The best way to solve the problem is to use a specific imager technology to apply a texture pattern on the surface of the plate that breaks up the surface patterns from the anilox roll. By breaking up the anilox pattern, it breaks up the pin-hole pattern, and significantly improves the ink transfer. As I noted in my last installment, that solution exists today and has been driving improved quality in flexo around the world.

Kodak’s innovative, award-winning KODAK DIGICAP NX Patterning is a standard component of the KODAK FLEXCEL NX System designed to address these ink challenges in flexo—specifically solid ink densities compared to gravure printing. Enabled by KODAK SQUARESPOT Imaging Technology, unique to the FLEXCEL NX System, the function of DIGICAP NX Patterning is to image a unique pattern into the surface of the plate.

Compared to traditional surface patterning technologies, DIGICAP NX Patterning is significantly smaller and finer. It is a true micro surface texturization of the plate surface, applied to the 1-bit TIFF in the RIPing process, and utilizing half-pixel imaging at 10.6 x 5.3 microns size, or 2400 x 4800 dpi.

With the ability to create unique patterns in the surface of the plate that overcome production challenges with heavy solid areas, or the application of white ink for flexible packaging, users are seeing dramatic quality improvements. Because of the improved ink transfer, printers are able to more easily achieve their target densities and eliminate the need to chase density with more ink, more pigment, and more pressure. For flexo printers, the result is greater color gamuts, cleaner brighter colors, better print quality, higher print speeds, and greater consistency.

Why are color gamuts improved with this solution? Because the solids are clean rather than being pin-holed, which results in light and dark variation in the colors, often the cause of the term “muddy” colors associated with Flexo. Also, when overprinting to build colors such as in 4- or 7-color process, the results are cleaner and brighter. Having the ability to build cleaner and brighter colors enables flexo printers to do more of their work with process printing instead of having to rely on more expensive spot colors. It also improves the printer’s ability to standardize ink sets, whether for 4- or 7-color process printing.

DIGICAP NX Patterning has been one of the lead technologies in the “flexo revolution” over the last five years, truly allowing printers to achieve the densities of gravure printing, and helping to stop the chase for density caused by excessive pin-holing with traditional flexo. It has been a key enabler in brand owners increasingly accepting that flexo is no longer a second-class print process, easing the transition from offset and rotogravure to flexo.

Innovation in flexo is an ongoing process, and one in which Kodak maintains a passionate commitment. R&D teams continue to explore additional areas where differentiated plate imaging technology can further increase print quality and reduce or eliminate production obstacles. As we look to the future, Kodak technologies such as DIGICAP NX Patterning, SQUARESPOT Imaging Technology, and KODAK HYPERFLEX Imaging Software will provide the foundation for technical advancements in flexo.
Printers are certainly benefiting from these innovative imaging technologies, but they are not the only ones. Brand owners are constantly looking for ways to design packages that catch the eye of the consumer and set their products apart from the competition. Print quality, color vibrancy, and reproduction accuracy are top of mind for marketers—it’s the job of the printer to make it happen and to keep costs in line.

What measurement condition is your spectro wearing?

by John Seymour, John the Math Guy

These days, all the fashionable spectrophotometers are sporting the new measurement condition, M1. It’s all the rage from Alabama to Aukland. If your spectro hasn’t adopted this new look, then, sorry. It just won’t get invited to the parties with all the cool spectros.

But what is this hip new fashion trend, and why should you care? This blog post goes undercover to get the inside story about the new measurement conditions in ISO 13655. This reporter investigates the four measurement conditions (M1 through M3), but more importantly, explains why you would choose one over the other.

Summary of the measurement conditions
Way back in 2009, when all of our spectros were wearing styles appropriate to that long-lost era, the ISO Technical Committee 130 came out with a new fashion edict. Spectral measurements henceforth shall be made according to one of four types of illumination, and the one chosen shall be reported along with the data.
(Note that the word “shall” is standards-speak for “you gotta do this if you want to comply with the standard. The other key word is “should”, which means “as experts, we recommend doing this, but it is not a requirement for compliance”.)
Why all the fuss? The big driving force behind this is the proliferation of Fluorescent Whitening Agents (FWAs) in paper. These are substances (stilbenes, for the chemists and lingo-philes in the crowd) that absorb ultraviolet light and re-emit that energy as blue light. This makes paper look whiter – which is what everyone wants and craves.I should make a note here. The popular media (Fox News and MSNBC) call them “OBAs”, meaning “Optical Whitening Agents”. While this moniker is correct – stilbene does make paper brighter in an optical kind of way – I would say that so does TiO2 and bleach. The term “OBA” fails to emphasize the key operative, which is fluorescent light.I have already written a bit about the basic problem and the reponse to it. The following exciting articles focus on the “M1″ stuff.
Layman’s Guide to ISO Print Standards
Here are the four exciting choices for measurement conditions:

Most handheld spectros use an incandescent bulb to illuminate the sample. Remember those kinda lights? A little piece of wire called a “filament”? Some electricity going through it? And then the wire gets hot and glows. Guess what? This light source doesn’t have all that much UV content. And guess what again? The amount of UV varies a lot from one instrument to the next.

M0 is based on a hypothetical incandescent light source. For an M0 measurement, the light hitting the sample should(note the word) conform to CIE standard illuminant A – which is to say, a light bulb. The word “should” is important and intentional. This little tiny loophole allows anyone to use the older spectros and remain compliant. This would be a totally dumb idea, but you could use a lightning bug with a hangover as the light source for your M0 illuminant and still be compliant. No one’s gonna check. M0 is the nightclub that any spectro can enter.

If you want to find out if your local neighborhood color scientist is hip, just ask whether he or she is raving about M1. All the hip ones will say M1. The illumination for this measurement condition is based on a theoretical daylight called D50. This puppy packs a pretty good wallop of UV content, so this will excite those ol’ OBAs, if you know what I mean.

Does your spectro want to strut its stuff at the M1 Bistro? The security guard is checking IDs at the door, and any spectro failing to provide the proper levels of OBA ain’t gonna be ordering an avocado-tini at this joint.

OBAs love attention. The only reason they show up at parties is to be seen. But when the spectrophotometer breaks out it’s M2 light source, the OBAs become as invisible as that woman who married Jimmy Fallon. An M2 light source will be almost kinda completely devoid of UV light.

How do you get into this club?  If your spectro comes knocking at the door, there will be a test, and I’m, not talking “written exam”. The test is described in Annex H. To perform the test, you need to get pretty intimate with the instrument. It would make a TSA agent blush.BTW, the TAGA 2015 conference in Albuquerque (March 22-25, 2015) will feature a micro-conference on OBAs. We had a whole bunch of papers on the subject, so the VP of papers decided to talk it up big. Here I am, talking it up big.M2 might seriously have been considered a contender for preferred condition. It does level the playing field when it comes to UV excitation. All M2 instruments have no UV, so none of them should cause OBAs to glow. And they should all agree.But, to make this whole opera work, the light booths really should have the same amount of UV content. And if there were no UV content in the viewing booth, then papers with OBAs would look dingy. And no one wants that.

You may think that M2 is an exclusive club, but M3 is even more exclusive. First you need to get into the M2 club even to be able to bribe the bouncer to get into M3. And you gotta be wearing sunglasses. Not just any sunglasses, but sunglasses with polarizing filters. As a result, specular highlights and fluorescence are not allowed in M3 disco.

So… if you happen to be thinking about dating a spectro, how do you decide which one is right for you?

Do I smell OBAs?

Do you have OBAs?
I know this probably sounds personal, but the first concern is whether you have OBAs in the house. If you don’t have OBAs, then (theoretically), there should be no difference between M0, M1, and M2 measurements. You could use your older instrument that doesn’t offer a choice, or you could go with one of the newer instruments that offer M1.

That question “do you have OBAs?” is pretty much the same as “are you measuring paper?” The thing is, paper is normally brown – the color of a grocery bag. Special processing must be done to make paper white. That could involve bleaching, or it could involve OBAs. Today, almost all paper uses at least some of the latter.

So if you happen to be measuring ink on paper, then you just gotta plunk your money down for an M1 instrument, because you will find your old M0 instrument disagreeable. It will disagree with your light booth, with M1 instruments, and even with M0 instruments from other families. The thing is that pretty much all paper for commercial printing will have OBAs added, so you have a choice as to whether to deal with a petulant teenager, so buy into the M1 craze.

I should add that switching over to the M1 instrument is only part of the change that you are facing. When you make the change, you will find that you need to make sure that your lighting booth adheres to the 2009 version of ISO 3664, so it has the same amount of UV content as the spectro. And all the data that you had previously measured, like profiles of your press and target colors, will need to be updated. I know, not a simple solution.

That covers web offset, sheetfed, and newspaper printing. The situation in packaging is a bit more complicated, so let me describe some cases. Let’s say that you are measuring color on foils or poly. I might be wrong here, but I don’t think you will run into any OBAs. Foils and poly and the floodcoat use something like TiO2 to add whiteness and opacity. Floodcoats wouldn’t benefit by OBAs, since they are not brown. So, like I said, I could be wrong, but I think it would be silly potatoes to add OBAs to foils.

If you are measuring kraft paper, then I think you are likely free and clear as well. If the paper is brown, then clearly no one cared enough to take the time to add OBAs to make it white. Then again, if the kraft paper includes a certain amount of recycled paper, then the OBAs might be sneaking in through the back door.

UV LED “blacklight” flashlight from Amazon for $12.89

How about printing on white cardboard or card stock? Now things get uncertain. You gotta ask yourself, how did the cardboard get white?  Sometimes, cardboard is made white by applying a floodcoat of white stuff. This white stuff might be something like titanium dioxide, which is naturally white. So, it is unlikely to contain OBAs. Then again, cardboard may be white because it has been laminated with paper. If that paper is white, then you can guess that it has OBAs. Another possibility is that the white card stock might be white because the paper is white. So, it could have OBAs.When in doubt… I would recommend having a UV light source around. Anyone who survived the sixties is familiar with these. Today you can get UV flashlights made from LEDs. Cheap and convenient, and a good way to test for the presence of OBAs.

Do you want CIELAB values?
The second concern is whether you want CIELAB values. In my not-always-humble opinion, computing CIELAB values from a polarized instrument (that is, M3) is just plain silly. The whole point of CIELAB is to emulate how our eyes see color. Unless your product is destined to be viewed by people wearing polarized sunglasses under light that is polarized the other way, then CIELAB is probably the wrong choice.

ISO 13655:2009 agrees with me on this one. Here is a quote from Annex G:

Notwithstanding the beneficial effects of crossed polarizers [M3] in the special cases mentioned above it needs to be noted that for most other instances in colorimetry the use of polarizers is counterproductive.

So, if you want to compute CIELAB values, then you must use M0, M1, or M2.

Are you doing process control on a cold set press?
M3 does not mix with CIELAB, but it does mix with density. ISO 13655 has this to say about where the M3 condition might be applicable:

It was discovered that the installation of crossed polarizing filters serves to extend the linear part of the density versus ink film thickness dependence towards higher values, and serves to greatly reduce density dry-back.

There are two points here. The first is that M3 “extends the linear relationship between density and ink film thickness.” This is believed by many, but it is unfortunately incorrect. In my blog post on polarized densitometers I presented a plot showing that there is a linear relationship between polarized and unpolarized density. If polarized density is linear with ink film thickness, then unpolarized must be as well.

The second point from the ISO 13655 quote is that M3 reduces dry-back. Measurements made directly after printing on a cold set press will not change as the ink dries. This is true, and that was really the whole point of the blog post on polarized densitometers. So… I won’t belabor the point here. But I will encourage you to go read the post.

And I will also reiterate a point that I have iterated a couple three times in previous blog posts. There is a difference between “process control” and “satisfying-your-customer control”. The first is about making sure your process is appropriate and repeatable. The second is about making sure that the payments from your customer are appropriate and repeatable. Density and M3 are process control parameters. CIELAB is a product expectation control parameter.

So, M3 can be useful when you are measuring ink that is not quite dry, but its use should be limited to within a given plant. No interchanging of data, you hear?

Are you doing process control on materials with OBAs?
Just in case you have been just too enthralled with this page-turner of a blog post to have been keeping track…

M0 is ok if you have a legacy instrument, and you aren’t really that into OBAs.
M1 is preferred, especially if you might think you have a little issue with OBAs.
M3 is acceptable, but only for process control – no CIELAB allowed.

What about M2?
OBAs are tricky little devils. They make the paper look whiter. But when you apply ink to them, a funny thing happens. The ink blocks the UV, so that the paper under the ink does not get artificially brightened. This can make things a little weird if you are a process control freak. Especially when you come upon an ink that doesn’t happen to block the OBAs. The relationship between the density of the paper and the density of the solid ink gets befuddled.

That last paragraph was written yesterday. This morning, I looked at some data that I got from my good buddy, Gerry Gerlach. His data refutes the stupid statement that I made “The ink blocks the UV.” Good God! What was I thinking. In his data, cyan, magenta, and black all do a pretty good job of blocking the UV. But for yellow ink (and aqueous coating on bare paper) there is a large difference in b* between the M1 and M2 measurements. In other words, the ink and coating are letting the UV light through, i.e. are transparent in the UV. I suspect that not all yellow inks do that, and certainly clear coatings may differ.

So, M2 is a process control thing, maybe better than M1. If you are trying to establish that you are putting a consistent amount of pigment on the paper from day to day, this might be a good thing to try. But as with M3, I caution that this is not the same as making the correct color.

M2 has found another purpose in life just recently with the invention of the OBA index of a paper. It has been noted that OBAs will tend to decrease the b* of a paper. A substrate might measure a little yellowish under M2, maybe b* is +2. If you measure that same substrate under M1, the b* might go negative, maybe -3. The OBA is the difference between the M2 and M1 measurements. In this example, the OBA index would be 5.

Are you sufficiently confused?
I hope this has blog post on illumination conditions been enlightening, no pun intended. Actually, the pun was intended. But the enlightenment was also intended.

A Guide to Reflectance Measurement Devices, Part 3

by John Seymour, John the Math Guy

I continue my action-packed series on the plethora of devices for measuring reflectance. Today’s topic is the spherical instrument. This blog post promises to be exciting because I know virtually nothing about the topic. This of course is generally the case when I write a blog, but in this case, I might actually admit to being ignorant if you get enough beer in me. Please try.In the first part of this series, I made the comment that your choice of instrument may not be directly related to which type works the best, but may be dictated by which industry you are in. If you are in the print industry, you are likely to be using (or required to be using) a 0/45 instrument. But, if you are measuring textiles or paint…

Are you measuring either cloth or paint?
If, by chance, you told the reflectance measurement device salesperson that you were in textiles or paint (personally, I am in lady’s underwear), then she would most likely point you to the integrating sphere section of the store. There you would see a few shelves of instruments that are labelled either 8/d or d/8. These are in the “spherical instruments” department.

When paint and textiles collide


An instrument that is 8/d will have illumination that hits the sample at 8 degrees, which is to say, just off the axis perpendicular to the sample. Light will be collected democratically — without regard to race, creed, or direction of travel when leaving the sample. This certainly has a satisfying feel to it. It should appeal to the physicist in all of us to know that we are collecting pretty much all of the reflected light. So that’s good.


The picture below shows how this is accomplished. Light enters through a port near the top of the sphere. When light reflects from the sample in all directions it hits the inside of the sphere. The inside of the sphere is coated with stuff that is highly reflective and very matte, so the light bounces off in all directions. And then this light hits the inside of the sphere again, and bounces yet again. Eventually, some of the light hits the detector and is measured. That sphere, by the way, is called an integrating sphere.

(from “The Measurement of Appearance” by Richard S. Hunter, John Wiley, 1975)


While it feels good to collect all the light, on the other hand, this is clearly not a measurement geometry that simulates anything in the real world. Light comes in at one angle – that part is reasonable enough – and is measured (seen) at all angles. What? Who has eyes like that??!?!


On the third hand, remember what my high school buddy, Herrmann von Helmholtz said: you can switch the illumination and viewing and see the same thing? So, 8/d will give you the same numbers as d/8. And a d/8 measurement is more or less what you get when you look at a car on a cloudy day… illuminated from all directions (well, mostly), and viewed at close to straight on (well, sometimes). The pictures above and below are from one company that bragged about both d/8 and 8/d designs while I was in high school.

(from US Patent 4,093,991, assigned to Hunter Labs, 1977)


SPINing and SPEXing
When using a d/8 or an 8/d instrument, you have yet another decision to make: SPIN and SPEX? These stand for SPecular INcluded and SPecular EXcluded. As with a polarized versus non-polarized spectrophotometer, this is an attempt to differentiate between the bulk reflection and the specular.

The SPIN instrument is just what I described previously. The light is captured from all directions without regard to race, creed, or sign of the zodiac. A SPEX instrument is almost the same, except that a black plug is put at the specular angle (at 8 degrees opposite the illumination). This keeps the detector from ever seeing this specular light. Clever, eh?

Depending on what you are doing with the measurements, one or the other might be more better. Consult your bartender or cosmetician for further advice.

Why is a spherical instrument good for cloth?
There is an inherent problem when you try to measure textured cloth with a 45/0 instrument. The texture will block 45 degree light from getting very far inside the warps and woofs of the cloth. The detector will miss out on seeing that rich color deep down in the fabric. Under typical conditions, our eye will see that light reflected from deep inside, since we normally have light that is hitting the fabric at angles other than 45 degrees. I might add that the fabric I most enjoy viewing is not presented as a flat piece. I much prefer fabric that has some curves to it.So, a spherical instrument has a big advantage when it comes to cloth, or carpet, or textured paint.
 Measuring a lion's tongue
This man is measuring the rough surface of a lion’s tongue with a 0/45 spectro.
I don’t recommend this.


Why is a spherical instrument good for paint?
You want your paint formulation software to work? Don’t even think about using a 0/45 spectrophotometer! A 0/45 spectro is very sensitive to the roughness of the surface that you are painting. If you mix the pigments of the paint based on measurements of one surface and then paint a surface that has a different roughness, guess what? The 0/45 spectro will see a different color. A spherical instrument is more forgiving.

That’s the good part. You can paint one surface to get your paint recipe and the use that paint on another surface and measure the same color with your spherical instrument.

But the bad part is that a spherical instrument is more forgiving – probably more forgiving than the flibbertigibbet who may or may not pay you because the house paint is the wrong color. Generally speaking, measurements made with a 0/45 spectrophotometer correlate better with what we see. Note that I have italicized those words for the benefit of those people who will disagree with me.

This is a point that I find myself making over and over again… process control versus customer needs. Frankly, I am getting sick of talking about it. Some day, I’ll just dedicate a whole blog post to the subject and stop ranting to my therapist.

What if you live at the intersection of textile and print?
 There are some poor sods who find themselves needing to make printed stuff look like textured textiles. Which type of spectro should they use?!?!?
The choice
Textiles or graphic arts?


Some of these poor sods are printers of catalogs. The color of the dress is critical, so they measure the lady’s dress. What do they measure it with? A spherical instrument, of course. Then they go print it and wind up measuring the printed catalog with a 0/45 spectro.

There are also some poor sods who get stuck having to print proofs of textile designs. Once again, we have the graphic arts world crashing into the textile world.

What to do about this? It’s tough, but if the fabric has a mostly kinda sorta matte finish, then the two instruments (d/8 SPEX and 0/45) will read similarly. Just be careful when trying to critically compare numbers from one type of instrument to another.

Are you decorating cans?
 For those who are not in the know, “decorating” is the official way to describe putting ink on soda and beer cans. I know, it sounds kinda froo-froo, but I didn’t make up the term. Most of what I say in these blogs is made up, but this particular factoid is true.
If you are in the can decorating business, and are looking to buy a spectro, then you have to ask the follow-up question: Coke or Pepsi? One of these companies requires that cans be measured with 0/45, and the other with spherical. If I can be trusted to explain their reasoning, one company realizes that 0/45 correlates better with what we see. The other company realizes that 0/45 measurements are hard to duplicate, since positioning is critical.
Coke or Pepsi
One of these is measured 0/45, and the other d/8
