ABSTRACT:
Letterpress and offset photopolymer printing plates are disclosed having relatively thin water developable photopolymer layers, which, after being developed, have ink-repulsive, non-image areas. Adhesive layers are provided in the disclosed printing plates that are interposed between an ink-repulsive coating contained in the printing plate substrate and the water-developable photopolymer, and provide a balance between satisfactory adhesive and ink-repulsive properties in the resulting plate.
