Abstract

1414122 Photographic colour separation record production J R DENNER 9 Jan 1973 [12 Oct 1971] 47477/71 Headings G2C and G2X Colour separation records of an original are prepared by making a same-size colour-correction mask or masks of the original, exposing the original and the mask or one of the masks together to produce a colour-corrected transparency of the original and preparing a plurality of colour-separated records from a single said transparency. The colour-corrected transparency is preferably of reduced size. A plurality of single colour-corrected transparencies of respective originals may be planned up together on a single clear carrier and a plurality of colourseparated records may be prepared of the composite formed. The colour-separation records produced are preferably full size and may be used to produce printing plates. In this invention colour correction is effected before colourseparation record production whereas previously colour correction was effected at the same time as or after colour-separation record production.
