Patent ID: 7253922

Claim:
A printing apparatus that is provided with multiple achromatic color inks having different densities and creates a diversity of dots with the multiple achromatic color inks on a printing medium according to image data, thus printing a monochromatic image, said printing apparatus comprising: a chromatic color ink receiver that receives at least one chromatic color ink; a monochromatic hue setting module that sets a monochromatic hue that a monochromatic image has as a whole when carrying out monochromatic printing; and a chromatic color dot creation module that creates dots with the at least one chromatic color ink at a predetermined density according to lightness information included in the image data, the chromatic color dot creation module further creating dots with at least one achromatic color ink of multiple achromatic color inks having different densities, wherein the dots created with the at least one chromatic color ink are configured to be mixed with the dots created with the at least one of the multiple achromatic color inks so that a printed image has the monochromatic hue set by the monochromatic hue setting module.
