ABSTRACT:
Photopolymerizable elements are described comprising a sheet support, a photopolymerizable layer having a thickness of, at most, 0.0006 inch (0.015 mm.) and an optical density of at least 3.0 in the actinic region. Resist images made from these elements may be etched by a process of chemically undercutting the image areas and then spraying or rubbing them. At least two dot-etched photopolymerizable elements, each exposed through a different color separation negative and colored accordingly, are placed in registration to form a color proofing system.
