Abstract A technique of the present invention uses dark yellow (DY) ink, in addition to a plurality of conventionally used basic color inks including cyan (C) ink, magenta (M) ink, and yellow (Y) ink. The technique may cause a printer to create dots with the DY ink, in place of creation of dots with the Y, C, and M inks. This arrangement enhances the degree of freedom in specification of dot on-off conditions of the respective inks, and relieves the restriction of ink duty, thereby enabling a resulting printed image to have higher picture quality.
