Patent ID: 8376502

Claim:
A method of generating a color separation table used by an image forming device that applies colored inks and an uncolored ink on a recording medium to form an image, the method comprising: using a processor to perform the steps of: acquiring a relationship between applying amounts of the colored inks and a thickness of a layer of a color material formed on a recording medium, and a relationship between an applying amount of the uncolored ink and the thickness of the layer of the color material formed on the recording medium; determining, based on the relationships between the applying amounts and the thickness of the layer of the color material, the applying amounts of the colored inks and the applying amount of the uncolored ink to substantially uniform the thickness of the layer of the color material when forming an image on a recording medium; and generating a color separation table for color-separating image data based on the applying amounts of the colored inks and the applying amount of the uncolored ink.
