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 […]

Differences Between Aqueous and UV Coatings

Coating Differences

First and foremost both Aqueous (water-based) and UV coatings have achieved wide spread use in the Graphics Arts Industry as competing top coats. Both offer aesthetic enhancement and protection, adding value to a variety of printed products.

Aqueous Coatings: Storing, Handling & Using

Aqueous Coatings

Opening Aqueous Coatings Aqueous coatings may be thermoplastic or thermoset, emulsion or solution polymer blends. The major volatile component is water along with small percentages of other volatile items. Some of these, such as ammonia or amine can evaporate and accumulate in the headspace of a sealed container, therefore opening is best done in a […]

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.

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 […]

Work & Turn Aqueous Coatings

Aqueous Coating

Work & Turn Work & Turn is a term used to describe the sheetfed litho practice of printing on both sides of a substrate. Typically, the first printing pass prints one side of the substrate. A second printing press pass follows as the job is turned and fed through the press again. The second pass […]
