Using Humidity Control to Optimize Pressroom Productivity

Pressroom Humidity Control

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 […]

Foam can be a Problem in Coatings

Coating Foaming

How Foam is Formed Foam consists of bubbles that are formed when air or a gas is trapped in a liquid or solid substance. Certain conditions are required for foam to be formed. Mechanical work or agitation is required, as are surfactants that reduce surface tension, so that work increases surface area. Also, foam must […]

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 […]
