ABSTRACT:
In a data creating method for creating image data corresponding to each of a plurality of color inks applied to a black image area formed on the basis of image data on a black ink, with the plurality of color inks being a cyan ink, a magenta ink, and a yellow ink, an image data creating step creates image data corresponding to each of the plurality of color inks on the basis of the image data on the black ink. The image data creating step creates the image data on each of the plurality of color inks so that the rate of areas in which all the plurality of color inks are applied, in the black image area, is higher than that of areas to which only some of the plurality of color inks are applied. At least one of the cyan ink, the magenta ink, and the yellow ink contains a component that coagulates a color material of the black ink.
