ABSTRACT:
A method of image reproduction is disclosed wherein an image is reproduced by selectively activating a surface of an image transfer body to form a tackified image configuration on the surface and contacting the surface with a transfer developer material which adheres to the tacky surface in image configuration. The developer material comprises a sublimable dye. The transfer body surface is positioned adjacent a surface of a receiving body and the adhering developer material is heated to a temperature for causing the dye to sublimate and thereby transfer in image configuration to the adjacent surface of the receiver body. The transfer and receiver bodies are separated and a reproduction of the image is retained on the receiver body. A number of copies are produced by repeatedly replacing the receiver body and reheating the adhering material. A reproduction master for use with this method is also disclosed.
