ABSTRACT:
An apparatus and method is disclosed which will rapidly provide uniform layers of two liquid photopolymerizable materials for a capped (i.e., two layer) printing plate. The apparatus comprises a dual manifold which spans the plate-forming area of a surface and which is moved in tandem transversely in order to provide two overlapping layers of liquid photopolymerizable materials.
