ABSTRACT:
In a method of image reproduction in which both pictures and test are to be combined in an image on a single sheet for use in the reproduction of a printed page, and in which the signals resulting from the scanning of the pictures are stored prior to the preparation of the sheet, a high resolution is achieved in the reproduction of the text without requiring excessive storage capacity for the picture signals by scanning the text at a resolution which is an integral multiple n of the picture resolution and, when the text and picture signals are merged to control an output scanner operating at the higher resolution, applying each line of picture signals extracted from store n successive times to the output scanner.
