Abstract (en)
[origin: US4269932A] A process for producing a relief original information carrier is disclosed comprising the steps of exposing a recording layer mounted on a carrier to a grating pattern, image-wise exposing the recording layer through at least one of individual color separation originals to form relief part-images and developing the exposed recording layer. The grating pattern exposure is made for a time sufficient to provide, upon subsequent development, a uniform relief depth corresponding to a certain predetermined color. The subsequent image-wise exposure is made utilizing individual color separation originals which are transparent in the areas of the particular projection colors of the individual color separation originals and which form relief part-images of the projection color which adjoin one another without overlap.
