Abstract
The most straightforward way of halftoning a color image is to halftone its cyan, magenta, and yellow channels independently. It has been shown in literature that halftoning the color channels dependently and using dot-off-dot strategy as much as possible will improve the print quality. Since a yellow dot on white substrate is much less visible than the other two colored dots in a number of methods only the C and M channels are halftoned dependently and the Y channel is halftoned independent of the two others. In this paper we will show that preventing the yellow dots from being printed on blue dots will improve the print quality and results in smoother textures. The color reproduction and the ink consumption for the proposed dependent color halftoning are also discussed.
