ABSTRACT:
An assembly for the deposition of aqueous coating compositions in printing processes including wet-trap in-line, off-line dry-trap, gravure, offset (using water and waterless), silk-screen, flexography and related printing processes. Use of the present invention results in the adaption of an aqueous coating to virtually any coating method without the need to change the chemical content of that formulation and in certain embodiments, produces unexpectedly high levels of solid being incorporated into printing coating compositions for obtaining levels of gloss on surfaces which have been heretofore unobtainable. In addition, the present invention is readily adaptable to virtually every type of coating process used to coat inked, uninked and related surfaces. The present invention also may be adapted for use of improved coatings without affecting the mechanical transfer to instill superior film characteristics, including high gloss value, increased film integrity and enhanced mar resistance without having to resort to the use of VOC's in coating formulations. Thus, in one aspect of the invention, by utilizing the present invention, an aqueous coating composition containing low VOC's or even an absence of VOC's can be generally adapted to a number of printing methods to provide exceptionally favorable transfer, especially including high gloss value.
