Abstract: A semiautomatic apparatus for processing the imaged surface of a printing plate. The apparatus includes an enclosed tray in which a plate is processed and a storage tank for processing liquid. In a processing cycle, the tank and tray are moved in timed sequence to transfer the liquid from the tank to the tray and back and to drain subsequently introduced wash water from the tray.

Abstract: A processor for photopolymerizable films is described. In this processor, film is fed, image up, in a straight through path by a series of soft rubber covered transport rollers first into a development section, then to a rinse section, and finally to a dryer section. In the developer section, developer is delivered through spray pipes which maintain a curtain of developer cascading over the top rolls at both the entrance and exit of the developer section. The film is thus maintained flooded in a precisely controlled, well defined surface region such that the time in which the film undergoes development may be accurately controlled by varying film speed. The film is then rinsed in the rinse section by a high impact spray system and then dried.
