ABSTRACT:
The present invention is directed to a method for producing a high gloss coating on a printed surface. In the present method, an aqueous coating composition is deposited onto a surface to be printed using a blanket roller coating face which is a low energy, non-stick, smooth surface profile. In the present method, simultaneous with the deposition of aqueous coating onto a substrate, or shortly thereafter, pressure either alone or in combination with heat may be applied to the coating in order to create a substantially tack-free surface conforming to the surface of the coating face. By using a highly polished coating face, high gloss coatings may be readily obtained using this methodology in a number of traditional printing techniques including wet trap inline sheet-fed printing, heat-set offset printing, dry trap inline flexographic printing, offset web-fed printing and gravure printing. Coatings which are produced utilizing the present invention have high gloss values heretofore unobtainable using aqueous coating compositions.
