<P>PROBLEM TO BE SOLVED: To provide an image forming apparatus capable of correcting color reproducibility such as a secondary color, a tertiary color, and a quaternary color. <P>SOLUTION: The image forming apparatus comprises: an image processing part, having a color conversion table, to output an image formation signal by performing a color conversion processing on image information to input, and an image formation part to print an image onto a sheet of paper with at least one or more printing colors based on the image formation signal. The image processing part corrects the color conversion table based on a correspondence relation between a prescribed printing ratio and a colorimetric value obtained by performing colorimetry of a test pattern of a plurality of patches having a different hue value or a prescribed print color ratio of 1 with which a printing is performed in the image formation part. <P>COPYRIGHT: (C)2012,JPO&INPIT |
