A Machine for High Speed Printing from 35mm Colour Transparencies

Abstract

A machine for making colour prints at high speed from 35mm. transparencies employs one operator to load the transparencies into a storage magazine, from which they are fed into the machine automatically and after printing are unloaded by a second operator. Information relating to each transparency loaded into the magazine is punched on to standard 5-hole paper tape. Colour quality of the light is controlled by varying the phase relationship between synchronously rotating sectored filter discs, and the light output of an Xenon discharge lamp, both being operated from the same A.C. supply.
