Abstract: A method and apparatus involving the generation of a digital screen at different screen angles for reproducing an image in raster form as a series of adjacent picture elements disposed along a plurality of adjacent parallel lines. The digital screen is generated by the repetition of one screen cell in first and second directions, each cell being divided into a series of unique address locations and each location being characterized by a selected optical density value. A memory array is provided for storage of the optical density values at address locations which correspond to address locations in the digital screen. The digital values of the actual picture elements in the image, which are obtained by scanning of the image, are compared to the screen values stored in the memory at corresponding addresses in order to generate output data signals defining the image to be reproduced.
