Abstract
1341219 Photographic printing apparatus EASTMAN KODAK CO 19 April 1971 [5 March 1970] 23076/71 Heading G2A Photographic printing apparatus has a first station 10 at which the optical properties of photographic transparencies 14 are measured to produce signals dependent thereon, which signals are stored in a data storage and control means 30, and a second station comprising one or more photographic printing means 50 for making prints from the transparencies, each printing means having an exposure gate 55 and receiving signals stored by the data storage and control means for making print exposures in accordance therewith. Each negative carries a punch code in a margin portion which is read and stored together with a measured density value upon a disc 32. Each printing means identifies a negative positioned in the exposure gate and upon coincidence with the recorded identification exposes a copy material 54 in dependence upon the recorded density value. The films are fed through the various stations by stepping motors 12, 52 controlled by the data storage and control means clock 28.
