Color Shift & Aqueous Coatings

Color Shift

The Success of Aqueous Coatings The use of aqueous coatings by the printing industry is, without doubt, a success story that now sees many millions of pounds of coating used annually to protect and enhance the printed material. This success has not always come easy, as the processes of printing involve many variables which must […]

Why and How Viscosity is Measured

Viscosity Zahn Cups

Viscosity Overview Viscosity is a measure of a fluid’s resistance to flow. It describes the internal friction of a moving fluid due to its molecular makeup. A high viscosity (thick) fluid resists motion because of high internal friction, while a low viscosity (thin) fluid flows readily because of low internal friction. Viscosity is measured because […]

Coatings & Anilox Transfer Efficiency To The Substrate

Flexo Style Chambered Doctor Blade Metering Coaters Flexo style chambered doctor blade metering coaters have become the dominant coater type used on sheet fed offset presses. They have proved capable of producing high levels of precise, repeatable application of clear coatings, and other fluid products. Integral to this success has been the development of the […]

Soft Touch Coatings Raise the Bar

Soft Touch

About Soft Touch Coatings Soft Touch coatings are able to provide products with a unique soft, warmer, more comfortable, luxurious, feel that humans intrinsically desire. The tactile, haptic effect provided is able to enhance the sensory perceptions of the consumer. Soft Touch coatings unquestionably add value to products as they impart appealing visual and tactile […]

Aqueous Coatings Boost Litho Productivity

Lithography Productivity Increase

Why use Aqueous Coatings in Lithography? Productivity! When a sheetfed offset lithographer is asked, “Why do you use overprint varnishes?” The stock answer is that conventional oleoresinous overprint press varnishes are used to protect conventional litho inks. An expanded answer adds that rub and scuff resistance can be improved and the finish can range from […]

Printing on Plastic Substrates can be Tricky

Printing on Plastic

Paper Substrates Forgive, Plastic Ones Do Not. Much has happened since we last wrote about printing on plastic substrates. Compared to a few years ago, many more printers are printing on plastic substrates and the variety of available substrates has increased, as has interest in printing on these materials, the result of innovative new applications.

What Is It About Viscosity?

Water Viscosity

What is Viscosity? Viscosity tells us how thick or thin a liquid is. Viscosity is the property of a fluid that causes it not to flow easily because of the resistance of its molecules. When we use coatings, we need to understand viscosity, because it is key to accurate application, and a finished coated product […]

UV/EB FDA Clearance For Direct Food Contact

Direct Food Contact Coatings

UV/EB Materials Since March 2008, Ultraviolet (UV) and Electron Beam (EB) ink, coating and adhesive formulations have been used in direct contact with food products. The change came about due to the efforts of the RadTech Food Packaging Alliance which was able to obtain FDA clearance for a number of UV/EB raw materials. This important FDA […]

Is it the Weather?

Different Weather types

High Temperatures and High Humidity June brings on summer in the northern hemisphere and with it the possibility of high temperatures and high humidity. The last decade has brought on several unusually hot summers and even warmer than usual winters. Whether or not global warming is caused by industrialization and its practices or the result […]
