Process for preparing surprint proof of an improved support

摘要

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 (98.48/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.
