Abstract: Vacuum printing apparatus is provided including a light box having an upwardly facing ground glass illuminated surface. A manually movable vacuum box is movable independently of the light box and is operated face down with a vacuum chamber above the photosensitive printing material and a transparency, the vacuum box resting on the light box for exposure.

Abstract: A film dryer is provided primarily for use in the graphic arts in which relatively large sheets of film must be processed and dried. A part of input rollers is of sufficiently hard rubber as to squeegee off most of the surface moisture which drops into a drip pan where it may be emptied. Subsequent guide rollers are of short axial extent and spaced apart. Air jets are slightly warmed and blow generally toward one another and against the surface of the film, and back toward the entrance, whereby to carry moisture back into the area of the drip tray for collection. O-rings or other resilient guides are positioned over suitable supporting structure to prevent the film from wrapping up about the various rollers.
