  • Patent number: 8376502
    Abstract: The relationship between the applying amounts of colored inks and the thickness of the layer of a color material formed on a recording medium, and the relationship between the applying amount of uncolored ink and the thickness of the layer of the color material formed on the recording medium are acquired. Based on the relationships between the applying amounts and the thickness of the layer of the color material, the applying amounts of colored inks and the applying amount of uncolored ink are determined to substantially uniform the thickness of the layer of the color material when forming an image on a recording medium. A color separation table for color-separating image data is generated based on the applying amounts of colored inks and the applying amount of uncolored ink.
