ABSTRACT:
A compact integrated system for film and print processing has chemical processing trays, sink, water filter and faucet, chemical storage, and drying screens integrated into a single multi-purpose unit. The processing trays are vertically stacked and rolled or slid in tray paths traversing the length of the sink. A print under development is directly transferred vertically between chemical processing trays across a print sponge with a print gripper. Each print is uniformly processed in a chemical processing tray by rolling or sliding the tray, ensuring uniform distribution of the processing chemical without manually agitating the print. The water rinse step of the print development process is accomplished in an oscillating wash bath wherein the water is continuously circulated over and between the prints being rinsed. Each of the processing chemical trays may be angled downward for emptying into a basin which can also provide a sink as well as safe recycling/disposal following print processing. A hinged top cover provides a secure mounting for a water filter/faucet, a combination light table and safe light, and a scaled work surface when closed.
