  • Patent number: 6740458
    Abstract: A printmaking process that utilizes phosphorescent transfer plates as the method for producing prints is disclosed. Specifically, this invention uses an engraved plate, which is coated with viscous phosphorescent paint. Once the paint on the plate is dry, the plate is exposed to light, causing the paint to become light-emitting. The plate is then placed in contact with photo-sensitive emulsion. After the proper exposure time, the photo-sensitive emulsion is developed, thereby producing a print. This invention can generate a wide array of prints. For example, black and white prints can be created under this invention. Further, prints containing a variation of tones between black and white and/or prints containing texture can be manufactured under this invention. Finally, color prints can be produced under this invention.
