  • Patent number: 5464729
    Abstract: A process for creating a thermal image for use in screen printing. The process includes the use of a photostencil film that consists of a clear transparent base carrier front side and an emulsion coated back side. The photostencil film is introduced into a thermal printer. The thermal printer is electronically coupled to a personal computer. The thermal printer is programmed to recognize digital information and convert the digital information into a thermal wax image. The thermal wax image is imprinted on the clear carrier front side of the photostencil film. Ultraviolet inhibitor additives and/or pigment opacity from the thermal printer provide the thermal wax image with an ultraviolet light barrier. All non-imprinted area's will remain photosensitive to ultraviolet light exposure. The photostencil film is fed through a light seal area into a timed ultraviolet light source. The carrier front side with the imprinted integral digital image is exposed to a timed ultraviolet light source.
