Aqueous and UV Coatings Tricks to Cleanup Process

Printing Separation

Aqueous and UV / EB Coatings have distinct cleanup methods that can make the processes run better.  This article will address specific tricks to cleanup before, during, and after press runs of aqueous, UV, and EB Coatings. Safety First and Second We will tackle the important steps in the cleanup of coatings for both Aqueous […]

Measuring Durability in Coatings with Abrasion Testing

Not a proper abrasion test!

How do we best test to predetermine the durability of printed/coated graphic arts products? Abrasion tests can determine the durability of printed and coated graphic arts. The durability of a printed coating is typically defined by such terms as, scuff, wear, rub, smudge, abrasion, blotching, and/or pick-off resistance. Historically a problem, defacing abrasion damage is […]

Advantages of UV LED Curing in the Print Industry

Internet of things

The advantages of UV LED light curing over the traditional mercury lamp have been pushing its growth. Explosive Growth Recently LED lighting technology, because of its low energy consumption and long life, has been eating up the competition while being rolled out with an explosive future trend playing out.  Research from Gartner, Inc. says that Smart LED […]

UV LED Light Curing is Booming

LED Lights

Once a lab curiosity, barely able to cure a UV ink, UV LEDs first appeared early in the 21st century as play things, and then later as commercially available curing devices. With very low power initially, power levels have increased to a point where curing applications emerged in the last few years. Progress to full […]

PFAS: Phasing Out Banned Chemical Compounds

PFAS Chemicals Banned

KNOWLEDGE IS POWER WITH REG’S PHASING-OUT BANNED PFAS Momentum is seemingly building to speed the phase-out of PFAS.  Some states have now taken action regarding its use in direct food contact packaging. Let’s review what we’re dealing with: Per- and polyfluoroalkyl substances (PFAS) made their appearance in the 1940s, due to the attractiveness of properties […]

Recycled Paperboard Presents Challenges

Recycled Paperboard Challenges

Yes, Recycled Paperboard is Different Recycled Paperboard can provide challenges to printing and coating processes.  Some time ago, we at Cork were astounded during a sheetfed litho aqueous coating trial.  Run on several varieties of recycled paperboard, inks would simply not set on one particular stock. This occurred after a successful in-line print/high gloss aqueous […]

Trends Affecting Printing & Coating Markets

Printing Trends

Trends that affect Printing and Coating Markets Covid-19 Accelerates Trends in Printing and Coating Various trends are in place that are now and will continue to affect printing and coating markets. Covid-19 has acted as an accelerant for these trends. When the initial reaction to Covid-19 locked-down world wide economies, businesses closed, people stayed home, […]

Electron Beam Applications’ Expanding Footprint

Electron Beam Applications Chart

Electron Beam (EB) does a lot of things, but perhaps the most significant one is the ability to break bonds of polymers.  When chemical bonds are broken, they produce free radicals (unpaired valence electrons), which are the drivers of free-radical chemical reactions.   These are the basis of the majority of present-day commercial EB applications.  An […]

Aqueous Coatings Fundamentals: Temperature, Pressure, & Viscosity

Aqueous Coating Temperature, Pressure, Viscosity

The Essence of Aqueous Coatings The practice of applying a coating successfully is a result of understanding and being attentive to a few fundamentals. These are pressure, viscosity, and pile temperature.  Success requires that these key variables be under control. Pressure in Aqueous Coatings PRESSURE: “KISS” is the key to a successful trouble-free coating application.  […]
