发明名称 Image processing apparatus and color conversion table generating method
摘要 An image processing apparatus includes a plurality of color conversion tables for color-separation-limited printing. Using a color conversion table for color-separation-limited printing, a piece of input color information corresponding to chromatic color within a specified applying hue range for a specified specific color is converted into a piece of output color information corresponding to color having hue of the specific color, and a piece of the input color information corresponding to color outside of the applying hue range is converted into a piece of the output color information corresponding to gray color. Each of the color conversion tables for color-separation-limited printing is configured such that color values corresponding to saturation and lightness of the output color information are reduced at least in gradation from a maximum saturation part to a low-lightness part.
