ABSTRACT:
A method and reproduction system for generating image information signals of a second type for each image point, upon supply of digital image information signals of a first type generated in a multi-bit form by a first and second signal source and making use of the information content concerning the density value present in the signals. The second signal source is adapted to generate image information signals in accordance with a predetermined density value. The image information signals of the second type are converted, by the application of grey value processing, to image reproduction signals which are used to control an image reproduction system such as a printer.
