The manner in which the paperboard is handled after printing and varnishing will dictate the importance of rub resistance in the choice of paperboard. Packing, distribution and handling by the consumer may also result in scuffing. Rub problems are prevented by using rub- resistant ink and varnish which is compatible with the absorption, setting, and drying properties of the paperboard. To increase rub resistance for special end use needs, the paperboard may need to be extrusion coated or laminated with plastic film.
