Abstract
Abstract A carrier sheet or film covered with a photo-hardenable emulsion of the desired color is placed in a vacuum frame in contact with the image to be copied and then exposed to ultraviolet light. The film is then developed and moved through a bath of liquid to which a compatible surfactant has been added, and scrubbed in this bath to remove the soluble emulsion therefrom by using a rotating spongy wheel moving over the surface of the emulsion faster than the film is moving through the liquid. All clinging surface liquid is then removed from the film by squeezing it between two sets of facing contacting ringers or rollers, and the film then rapidly dries in the air.

A PROCESS FOR PREPARING FILM OVERLAYS INCLUDING THE STEPS OF: A. SUBJECTING A FILM WITH A PHOTOHARDENABLE EMULSION THEREON TO AN IMAGE-WISE EXPOSURE OF LIGHT TO PRODUCE EXPOSED AND UNEXPOSED PORTIONS OF THE EMULSION; B. IMMERSING SAID EXPOSED FILM IN AT LEAST ONE ORGANIC SOLVENT WHICH WIL RENDER ONE OF THE EXPOSED AND UNEXPOSED EMULSION PORTIONS SOLUBLE WHILE LEAVING THE OTHER SUCH PORTION FIXED; C. REMOVING THE SOLUBLE EMULSION WITH THE FILM IMMERSED IN A LIQUID BATH BY SCRUBBING THE EMULSION SIDE OF SAID FILM UNDER THE SURFACE OF THE LIQUID WITH A RESILIENT, SOFT, LIQUID ABSORBENT MEMBER WHEREIN SAID SCRUBBING IS ACCOMPLISHED BY USE OF A ROLLER SHAPED SCRUBBING IS ACCOMTHE SCRUBBING ACTION IS ACCOMPLISHED BY SUPPORTING THE SIDE OF THE FILM OPPOSITE THE EMULSION SIDE ON A BACK-UP PLATE AND WITH THE EMULSION SIDE IN CONTACT WITH THE SCRUBBING ROLLER, AND BY ROTATING THE ROLLER WHILE MOVING THE FILM PAST THE ROLLER, THE ROTATION OF THE ROLLER BEING AT A HIGH ENOUGH SPEED SO THAT THE PERIPHERAL SPEED OF THE ROLLER SURFACE OVER THE EMULSION SIDE OF THE FILM IS CONSIDERABLY FASTER THAN THE RATE OF MOVEMENT OF THE FILM PAST THE ROLLER; D. REMOVING THE FILM FROM SAID BATH AND REMOVING ALL BEADS OF THE ADHERED LIQUID THEREFROM BY SQUEEZING IT BETWEEN TWO ADJACNET, RESILIENT CONTACTING ROLLERS WHICH MAKE FIRM CONTACT WITH THE FILM AND WHICH ARE ROTATING AT A SPEED SUCH THAT THE PERIPHERAL SPEED OF THE ROLLERS IS IDENTICAL WITH LINEAL SPEED OF THE FILM; AND E. ALLOWING THE FILM TO AIR DRY AFTER LEAVING SAID ADJACENT ROLLERS.
