ABSTRACT:
To impose a total-ink duty-cycle limitation by an ink-jet printer that substitutes black ink for simultaneous occurrences of cyan, magenta, and yellow, a printer driver determines a component-value adjustment as a function of the difference between a color's maximum and average component values. Adjusting the color values when this quantity is high but not when it is low enables one to prevent violation of the total-ink duty-cycle limit without unduly limiting black-ink use.
