PROBLEM TO BE SOLVED: To provide a technology capable of improving an image quality of a list image to be printed.SOLUTION: A print control device comprises a list print control unit U3 and a list color conversion table generation unit U2 and performs control for converting an input image D1 by referring to a color conversion table 310 in which used amounts (Ci, Mi, Yi, Ki, Lki and LLki) of color materials for printing are made correspondent to first grid points GD1 of an input color space (RGB color space), and printing an output image D5 after the conversion. The list print control unit U3 performs control for printing a list image D3 based on the input image D1 for adjusting the color conversion table 310 by referring to a list color conversion table 320 including second grid points GD2 of which the arrangement is different from that of the first grid points GD1. The list color conversion table generation unit U2 generates the list color conversion table 320 by arranging at least the second grid points GD2 at positions (720, 721 and 722) where the used amounts of the color materials specified in the color conversion table 310 become maximum, on a gray axis of the input color space.SELECTED DRAWING: Figure 1 |
