A reference marking device for image transmitters includes a transmitter (FIG. 1) and a receiver (FIG. 3). The transmitter includes a scanner, which optically scans an image, and generates an image signal corresponding to the content of the image. The receiver receives the image signal and records the received image signal on an image base as a reproduction of the scanned image. The image base is provided with reference marks for registration of a series of separate, associated image reproductions, obtained preferably by means of color separation of the scanned image. The transmitter additionally generates and transmits reference signals. A reproduction device, included in the receiver, registers said reference marks in correspondence with the reference signals. The transmitter transmits the reference signals to the receiver in such a manner that, upon repeated scanning of the image, the reference marks are generated in positions which are invariant relative to the content of the series of associated image reproductions. |
