ABSTRACT:
Process for preparation of improved surprint multilayer proof using at least three nonsilver photoimaged elements, e.g., positive-working photopolymerizable element or negative-working photosensitive element, having a thickness greater than 0.0001 inch (0.0025 mm) which are laminated sequentially to a pearlescent support having total luminous transmission not in excess of 25% and 20.degree. specular gloss in the range of 8 to 20 gloss units, e.g., biaxially oriented polyethylene terephthalate film filled with polypropylene and BaSO.sub.4. The surprints are useful in the web fed, publication web and sheet fed segments of the printing market.
