4 April 1997 Ink duty reduction for cluster dot halftoning
Author Affiliations +
One of the major problems encountered in the color halftoning on ink-jet printers is the problem of ink duty. Most commercial ink-jet printers will produce ink droplets that exceed the physical area of a single. While limiting the continuous tone ink is a valid solution for the dispersed or blue noise dithering, that method fails on cluster dot dither. Our method deals with the Ink Duty problem in the cluster dot case by 'punching out' holes in the halftoning pattern without altering its aspect and in a time efficient manner. Given a printer, we first determine the ink duty constants. Then a dither matrix will be used to remove enough dots locally in order to satisfy the (alpha) , (Beta) , (gamma) constraints.
