Top Recommendations for Work & Turn Aqueous Coatings

Work and Turn Offset Printing

Work and Turn Offset Printing Work & Turn, (W&T) as we know it, is a process familiar to the sheet-fed printer where the second side of a sheet is printed after the first side. This is accomplished normally by turning the sheet over from left to right using the same edge of the paper or […]

Aqueous Coatings & Foaming

Aqueous Foam

Aqueous Coatings are Complex Blends Aqueous coatings are complex blends of materials with a typical formula consisting of a mixture of aqueous emulsions, blended with additives to improve properties and performance. These additives are commonly, small quantities of an amine, a plasticizer, waxes, a surfactant, coalescent aids, and anti-foam agents.

What Is It About Viscosity?

Water Viscosity

Understanding and Testing of Viscosity in Coatings Viscosity tells us how thick or thin a liquid is. Coating 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, […]

Using Humidity Control to Optimize Pressroom Productivity

controlling pressroom humidity

OFFSET PRESSROOM AIR EVACUATION, WHY? The control of humidity is critical in offset printing in order to optimize productivity. It is well known that dry air causes paper to lose its moisture so that wrinkling, paper jams, and register issues are likely due to a pick-up in static electricity. A humidity level of 45 to […]

Special Effects using Matte, Satin, and Gloss Aqueous Coatings

Special Effects Aqueous Coatings

Aqueous Coatings create Special Effects Many different special effects may be obtained using aqueous coatings that are formulated to provide various levels of gloss. This range in gloss can extend from a very flat matte (reflecting only 15% of light) to very high gloss coatings that are able to reflect as high as 90% + […]

FDA Bans Chemicals in Food Packaging Coatings Update

FDA Bans Food Packing Chemicals

Perfluoroalkyl Ethyl Toxicity Concerns in Food Packaging In January 2016, the U.S. Food & Drug Administration (FDA) published a final rule that prohibited the use of three specific perfluoroalkyl ethyl containing chemicals because of toxicity concerns. These chemicals had been in use to make paper and paperboard packaging resistant to oil and water for use […]

Specialty UV Coatings Protection and Chemical Resistance

product protection

Our world is an ever-changing one as evidenced recently by the appearance of Covid-19, unusual weather, and ever-evolving new technologies and products. These changes are presenting both opportunities and challenges for UV coatings with their ability to resist attack by chemicals, and various consumer and industrial products. Currently, we are advised to wear masks, wash […]

Adhesion Factors of Surface Energy & Surface Tension

Surface Energy and Tension

A surface that is easy to wet is necessary when printing and coating in order to achieve good adhesion and appearance results. “Wetting” is the ability of a liquid to spread, contacting a solid surface. All liquids have a surface tension and all solids have a surface energy. Both are measured as a force applied over an area, expressed as a […]

Cold Foil Print Graphics Entice Shoppers

Cold Foiling

Cold Foiling growth and productivity improvements have come rapidly. Foiling is known for its ability to add eye-catching visual effects to all aspects of printing creating brand differentiation. Foiling has proven to be effective in attracting and persuading shoppers to choose one product over another.
