Abstract

A system of making custom transfers using as the image transfer implement clear or transparent polyvinyl chloride film in sheeting form that is pretreated in practicing the invention to have on its side that is to bear the image to be transferred a polyvinyl alcohol overcoated adhesion and release coating that forms an incipient image receiving transfer medium, in which system the image that is selected to be transferred is photographed to provide the image of same in the usual photographic negative format, and a section, of appropriate size, of the transfer implement serving film is severed from the stock of such film to provide a transfer sheet that is further processed for completing and sensitizing the sheet transfer medium for photographic application to same, and in enlarge form, the image to be transferred. In the processing of the film sheet that serves as the transfer implement, after being cut to size it is applied to, in accordance with the invention, a special resilient coating board and has a first sensitizing, color pigment free polyvinyl emulsion applied to the sheet incipient transfer medium that is dried and followed by a second coating of the sensitized polyvinyl emusion that at this time includes color pigment of the image color selected, which coating is again followed by drying. The thus treated film sheet transfer implement then has its transfer medium photographically exposed, using an ultra violet light equipped projector that mounts the negative bearing the image, for photographically applying the image to the transfer medium of the film sheet, and in enlarged form. After the exposure, the exposed film sheet is developed by employing water spray techniques to wash away the unexposed sensitized polyvinyl, which leaves as the transfer medium only the exposed polyvinyl that is pigment colored. After drying of the film sheet, the side of the film sheet bearing the finalized transfer medium has a uniform layer of suitable pressure sensitive adhesive applied over all areas thereof, and after drying, the transfer sheet may be immediately applied to transfer the transfer medium to a desired substrate surface, by burnishing the image against the surface and pulling the transfer sheet free of same, to leave the enlarged image in place, or stored in a release coated wrapping until needed.

Claims

1. A substrate for making custom transfers, said substrate comprising:

polyvinyl chloride sheeting of film dimension thickness having one side of same bearing a dry composited coating comprising a uniform base coating of a uniform mixture consisting of approximately twenty parts isopropyl alcohol, one part wax and one part talcum powder that is overlaid with a uniform coating of polyvinyl alcohol.

2. The substrate set forth in claim 1 wherein:

said sheeting has a thickness approximating 0.005 inch.

3. The method of making a substrate for making custom transfers, said method comprising:

taking a polyvinyl sheet of film dimensions and coating one side of same with a uniform mixture consisting of approximately twenty parts isopropyl alcohol, one part wax, and one part talcum powder,

drying said coating,

overcoating said coating with a uniform layer of an aqueous emulsion of polyvinyl alcohol,

and drying said overcoating.
