Abstract
Abstract Apparatus and method for making full color prints of a multicolor graphic original. The prints can be duplicates of the original or can be prints having colors for the various colors appearing in the original that have been synthesized to provide prints which are a "recoloring" of the original. The color data for synthesizing is stored in a permanent, machine readable form for later readout and use in controlling operation of the apparatus in order that the print from the original with synthesized colors can be easily reproduced without having to manually adjust controls for placing the necessary color data into the apparatus to obtain the desired "recolored" print.
