LEARN MOREFoam is the result of air distribution in the coating. Here, gaseous bubbles emerge in the coating or on the coating‘s surface. If foam occurs in the coating container or coating pan, processing problems may be the consequence. This is followed by transfer disturbances or air inclusions in the dried coating layer.
The coated printed product looses gloss and/or scuff resistance. If foam appears in the chambered doctor blade or roller system, a (partial) drying of the coating is possible. Depending on the level of contamination, this may even lead to malfunctions of the printing press. The most usual reason for foaming is the fast pumping of the coating in the container (circulation of coating suction and return flow) and in the printing press.
