摘要:
The present invention relates to a development material by means of a latent, colored image, obtained by laminating another, photopolymerizable material colored in a primary color onto an image-receiving material, peeling-off the film support and exposing the material under the associated negative color separation film, can be developed by laminating the development material onto the latent image and then peeling-off the development material together with the non-image areas. The invention also relates to a process for the production of a color proof using this development material in combination with photopolymerizable materials in the various primary colors.
摘要:
A method for producing a positive as well as a negative multicolor color-proof image.The invention relates to a color proofing process in which a multicolor image is produced from a plurality of single-color images in register with the aid of a colored, photosensitive, photopolymerizable material on an image-receiving material. Depending on the processing variant, both positive and negative film masters can be processed, even simultaneously on a single receiving material, and it is not necessary for the emission spectrum of the light source to be variable.

摘要:
The invention relates to a radiation-sensitive material comprising A) a multilayer support material, B) a colored photopolymerizable layer, and C) an adhesive layer. The multilayer support material consists of at least two sheet-form materials, which are bonded to one another in such a way that the adhesion between the two sheet-form materials is less than the adhesion between the radiation-sensitive layer and the adjacent support material. The invention furthermore relates to a process in which a colored image, in particular a multicolored image comprising a plurality of primary-color images, is produced on an image-receiving material. The color images are produced by laminating a colored photopolymerizable layer onto the image-receiving material, exposing the material under the relevant master, in particular a color separation, developing the image by peeling-off the support film from the photopolymerizable layer together with the non-image areas, and, if desired, repeating the same steps with a photopolymerizable layer in a different color.
