ABSTRACT:
A system wherein an image such as, for example, unscreened artwork is divided into sub-images each of which is digitized and is then represented by the digital code of a pattern that closely matches the sub-image. Thereafter, the image is reconstructed by reproducing the pattern equivalents of the sub-images to form a composite image.
