COLOR CONVERTING APPARATUS AND COLOR CONVERTING METHOD FOR DESIGNATED-COLOR PRINTING, AND COMPUTER READABLE RECORDING MEDIUM

摘要

A color converting apparatus is used for designated-color printing. The apparatus is provided with a color space converting unit for converting a designated-color designated by a printing command to a converted-color in a color space represented by brightness, saturation and hue of color, and a color classifying unit for classifying the converted-color to one of plural classified-colors on the basis of the brightness, saturation and hue of said converted-color. Color correlating-relationship information is prepared, which sets correlating relationship between the plural classified-colors and one or more printing colors. The apparatus is further provided with a classified-color/printing-color correlating unit for selecting one printing color correlated with the one classified-color from among one or more printing colors, based on the color correlating-relationship information and for correlating the selected printing color with the printing command.
