A weight is moveably positioned in the side opposite the side having a film entrance slot of a side opening x-ray cassette. When the plates holding the film are separated the weight acting under the influence of gravity aids in ejecting the film from the cassette.

Daylight x-ray cassette having a weight to improve film release

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 cm.sup.3 /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 BaSO.sub.4 or TiO.sub.2. The surprints are useful as pre-press proofs.

Process for preparing surprint proof of an improved support

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.
