Paper Abstract

The same image on the display and color printer isn't the same. Firstly, this is due to the bit depth difference for representing the color of a pixel. The display uses the color data of the eight or more bits, but the color printer uses just 1bit for representing color of a pixel. So, the display can reproduce smoother image than the color printer. Secondly, the display gamut is larger than the printer gamut, so the display color is brighter and more saturate than the printer color. For minimizing the problems due to these differences, many halftoning and gamut mapping techniques have been developed. For the gamut mapping, color management standard organization, ICC, recommended 2 gamut mapping methods, HPMINDE and SGCK. But the recommended methods by ICC have some weak points; contouring (HPMINDE), paled pure color reproduction (SGCK) and too reddish hair color reproduction (HPMINDE, SGCK). This paper introduces a gamut mapping method that can reproduce smooth gradation, pure colors with high saturation and natural hair color. The proposed method is developed for optimal reproduction of graphic image, and it also gives good results for pictorial image.
