ABSTRACT:
A method of processing images preparatory to printing in a color printer adapted to printing serial color separations, that when superposed form the final color image, in which separation color images are received for printing defined by continuous tone separation signals, which are color corrected and halftoned preparatory to printing the color image. The received continuous tone separation image signals are used to derive an estimate of marking material coverage. The marking material coverage estimate is subsequently used in association with random number generation to turn OFF otherwise ON pixels in each separation as the separation is printed for the reduction of marking material coverage.
