A coated paper product having high gloss and brightness is prepared by a process wherein a paper substrate is coated on at least one side with an aqueous coating formulation comprising an effective amount of a plastic pigment, and finished in a supercalender device containing heated rolls to produce a surface which is comparable to a cast coated surface.

High gloss coated paper

Web offset printing paper having a high level of gloss and smoothness is prepared by finishing a paper web, either by supercalender or with a synthetic roll calender at a moisture content greater than the moisture content typically used for web offset finishing, and then drying the web to a moisture content of less than about 3.5% using convection, radiation or conduction. Under the preferred post-drying conditions, bonding of the previously wet paper fibers takes place to lock in the desirable printing characteristics and to prevent heat roughening on the offset press.
