Abstract
1300843 Photographic colour printing AGFA-GEVAERT AG 23 March 1970 [21 March 1969] 13927/70 Heading G2A The spectral content of a light beam used to print a colour original is adjusted in accordance with the average spectral content of light transmitted through a plurality of originals. Originals contained on a supply reel 3 are fed past a measuring station 6 containing a light source 7 and photo-cells 9, 10, 11 which receive light in three primary colours respectively. An evaluation device 15 stores the measurements made on a group of originals, e.g. those contained on one length of film, and high density subtractive filters 27, 28, 29 are selectively positioned in the printing beam for all originals in the group as the result of the measurement when the first original of the group reaches printing window 19. Mirror 33 reflects a part of the printing beam onto a photocell 34 so as to terminate the exposure by a shutter 36. Individual films may be joined by adhesive tape, indentations (1b) Fig. 2 (not shown) being provided at the point where the films are spliced to control the measurement at station 6. The originals are illuminated via a mirror 24, mirror shaft 25 and a diffusion disc 26.
