ABSTRACT:
Screens for use in screen process printing are prepared by applying a dry emulsion film to a layer of liquid emulsion carried on the outer surface of a screen fabric in such a manner that upon drying, the dry emulsion film and the liquid emulsion layer are coalesced into a unitary emulsion layer which surrounds the screen fabric. The coalesced emulsion layer has a smooth surface which extends a uniform distance above the screen fabric. Screens thus produced are used to prepare photographic stencils for use in screen process printing.
