Photopolymer Printer-Processor (Exploratory Development)

摘要

An exploratory development model of a Photopolymer Printer-Processor, designed to make positive transparencies from 5-inch-wide aerial roll film by means of the photopolymer process, is evaluated. The equipment is contained in two separate units: a printer, viewer, and chopper in one unit; a processor and dryer in the second unit. The units weigh 80 pounds and 115 pounds, respectively. The light source in the printer is a 100-watt mercury arc tube; about 40 seconds are required for printing. After printing and chopping, the print is manually fed into the processor where it is gripped at the edges by conveyor belts and carried, emulsion side up, down an incline under a stream of 1 percent hydrogen peroxide. Processing and drying require 72 seconds per print. As presently designed, the equipment requires an amount of hydrogen peroxide and water that is excessive. (Author)
