Abstract: A color film supply apparatus has a supply roll holding unused color film. The apparatus simplifies the handling of the color film. For this purpose, the supply roll and a waste roll to hold used film are supported in a cassette-type, portable housing in a manner such that a length of the color film extends between the supply roll and the waste roll and the housing has, between the supply roll and the waste roll, an opening that is at least as wide as the color film and permits free access to both sides of the color film. In addition, a straight edge is located in the section of the housing containing the waste roll and deflects the travel path of the color film.

Abstract: Layer transfer process for image production wherein predetermined areas of the surface of an image carrier (21) are prepared to accept a color layer, the image carrier (21) and a color carrier (22) of layer transfer material are brought into mutual contact under pressure, and the color carrier is removed from the image carrier, so that color remains on the predetermined areas of the image carrier. A high uniformity of colorant application can be achieved over the entire surface of the image carrier. The process is performed by an apparatus with at least one roll nip (31) formed by two hard rolls (11, 12), preferably with different diameters, in which the two rolls are mutually offset relative to the feed direction (30) of the image carrier (21).

Abstract: The invention refers to an apparatus for testing the color separations of a multicolor print, comprising a pair of press rollers being mounted in a frame and constituted by rollers which can be lifted off each other, through the roller gap of which an image-bearing element consisting of a support foil with an exposed, photosensitive layer, with a color foil, consisting of a color-bearing foil with a color layer, being placed on this element, is fed such that portions of the color layer adhere to the tacky areas of the image-bearing element. For the solution of this problem to provide an apparatus of the kind by which the testing of the color separations of a multicolor print can be carried out in a simple and rapid manner, a movable frame is provided in which a plurality of pairs of roll bearings for rolls to be unwound and wound up are mounted.

Abstract: Image reproduction process using a photohardenable element for the production of negative tonable images comprising (1) support, (2) intermediate layer containing at least one thermoplastic binder, (3) photohardenable layer containing addition polymerizable monomeric compound or photocrosslinkable compound, (4) tonable layer comprising a polymeric binder and a non-volatile diffusible component, e.g., a plasticizer for the binder and (5) optionally removable cover sheet. The element is used for image reproduction, e.g., colored prints.
