ABSTRACT:
YMCK halftone dot percentage data from an image editor are converted into color image data in an XYZ colorimetric system with a common color space conversion table generated by a common color space conversion table generator. The color image data are converted into a gamut mapping and appearance corresponding to an image monitor device with a gamut mapping/appearance table generated by a gamut mapping/appearance generator. Then, the color image data are converted into color image data in a device color space of an image output unit with a device color space conversion table generated by a device color space conversion table generator for thereby predicting a color image which will be reproduced by the image output unit. Alternatively, the YMCK halftone dot percentage data from the image editor may be corrected using dot gain correcting coefficients established respectively for tristimulus values X, Y, Z, and then converted into color image data in the XYZ color space with a common color space conversion table.
