Roymal's controlled C.O.F coating (coefficient of friction) is formulated to give the most stable COF possible for a given ink and substrate system. The coatings do not use migratory additives which will cause changes in COF as the coatings age. Typically, these controlled COF coatings are applied to paper, paperboard and film using the standard printing processes, i.e., rotogravure, flexographic and offset.
