Abstract:
A method of controlling a color printer having a gamut that defines all colors that can be printed by the printer, the printer being connected in a computer system that contains a set of printer independent input signals that command the printer to print an output print that corresponds to the set of input signals, the method comprising the steps of:using the printer to print a plurality of output prints said plurality of output prints being representative of the gamut of the printer and comprising in the range of from about 101 to about 182 output prints; providing a neural network comprising in the range of from about 5 to about 7 neurons; using said plurality of output prints to train said neural network and thereby provide a gamut trained neural network for converting printer dependent color signals into printer independent color signals that correspond to the gamut of the printer; using said gamut trained neural network to generate a printer profile lookup table tabulating a series of printer independent color signals to a series of printer dependent color signals that correspond to the gamut of the printer; using said set of printer independent input signals to address said printer profile lookup table; and controlling the printer in accordance with a set of printer dependent color signals that correspond to the set of printer independent input signals.
