Paper Manufacture

Coated papers

. The press operator often uses the printing press to put a varnish coating on the paper after it has been printed, usually for protective or aesthetic purposes. However, the papermaker also may apply a coating to the surface of paper to make the paper more suitable to its end use. Coated papers are stocks that have received a mineral coating, usually clay, to improve their printability and appearance. They are available in a variety of finishes. Coatings improve paper whiteness, pick resistance, water resistance, ink holdout, paper opacity, gloss, and overall print quality. Usually, paper is coated on two sides (C2S).
