PROBLEM TO BE SOLVED: To permit an ink component dot to be inconspicuous by generating an ink color component by means of a portion to have prescribed relation to a lower color quantity being a min. common component in an element color and reducing the generation quantity as a brightness increases in the colors. SOLUTION: A computer system consists of a CPU system 100 and disk systems 201-203, etc. Then, the CPU system 100 generates the ink color component by multiplying the lower color quantity CMYmin being the min. common component in the plural element colors by a prescribed generation rate BGR in order to execute inking in color space for printing, which is constituted of the plural almost equal element colors such as CMY, etc. In this case, the generation rate BGR of the ink color component is made to be smaller as the color is brighter in relation to the brightness of a conversion source. Therefore, the generation quantity Kout of the ink color component is small at the time of the bright color in spite of the same lower color quantity CMYmin and the dot corresponding to the ink color component is made to be inconspicuous at the time of printing by referring to an obtained printing color conversion table.
