TITLE PROCESS FOR PREPARING SURPRINT PROOF ON AN IMPROVED SUPPORT ABSTRACT OF INVENTION Process for preparation of improved surprint multilayer proof using at least three nonplanar nonsilver photoimaged elements, i.e., negative-working photosensitive element which are laminated sequentially to a support having a permeability to air of less than 0.1 cm3/second, a peel adhesion value of at least 250 g/inch (98.49/cm) and a total luminous transmission not in excess of 25%. e.g., oriented polyethylene terephthalate film filled with polypropylene and/or with BaSO4 or TiO2. The surprints are useful as pre-press proofs.
