ABSTRACT:
An apparatus, a process and a processing sheet for improving qualities of an image in sharpness, density and/or glossiness. A copy or printed sheet having an image is coated with a thin sheet at the image bearing side of the copy. The copy is then pressed together with the thin sheet, and simultaneously heated so as to soften or fuse at least the surface of the image on the copy. Then, the sheet is peeled off the image after the image is cooled sufficiently. Surprisingly, the qualities of the image are improved as compared with the image before processing.
