Abstract

Method and apparatus for processing color images wherein a black ink having a low infiltrate rate and color inks having a high infiltration rate are used for color printing are described. In the method and apparatus, part of black image data is converted into image data for other colors so that part of a portion to be printed with black ink droplets is printed with color ink droplets. Alternatively, part of the portion may be printed with black ink dots and other color dots being superposed. By this, bleeding between black and other color inks can be suppressed with the resultant image being a black density and sharp edge when printed on ordinary paper.
