Abstract
932,543. Colour printing. GEVAERT PHOTO-PRODUCTEN N.V. Feb. 17, 1960 [Feb. 17, 1959], No. 5683/60. Drawings to Specification. Class 98 (2). A process of printing a photographic colour image on multicolour sensitive material of which the sensitivity ranges appertaining to different colour sensitive layers overlap comprises exposing the material to a light source emitting light which is in part within the spectral region common to the overlapping regions and providing an interference filter or filters to exclude or restrict the light within the common region. A single filter may be formed with two layers which transmit light on either side of a band to be excluded, e.g. one layer may transmit light of 700-510 mÁ and the other light of 470- 400 mÁ, the band between 470 and 510 mÁ being reflected.
