Abstract
The colors of a print as a target are easily and reliably equalized with the colors of a proof generated by a proofer. A printed color chart Cpa is colorimetrically measured by a colorimeter, and an original printing profile as a target for converting CMYK image data into colorimetric data is produced. Then, using the original printing profile and a printer profile, a color chart Cpa' of the proof is outputted from a printer based on the CMYK image data. The color chart Cpa' is colorimetrically measured to generate a printing color reproduction profile. In the printing color reproduction profile, weighting is set in view of color reproduction ranges of a printing press and the printer, and a corrected printing profile is generated. The corrected printing profile and the printer profile are set as a color converting means. It is possible to perform easily corrected color matching by using the corrected color converting means.
