Abstract

The gamut of color in digital color printer is discussed with a simple color mixing model based on Neugebauer theory. A colored halftone area is composed of at most 8 colored dots: Cyan, Magenta, Yellow, Red, Green, Blue, White, and Black. It is shown that a color gamut and a color-locus change by the 2 colored dot overlay method. Typical color changes in thermal transfer printer were observed experimentally in coincidence with theotretical estimations. The dot allocation of dither matrix causes the significant changes in the hue of red tone and the gamut of bluish colors.
