Abstract:
1. A computer readable recording medium staring program code for causing a computer to convert CMYK data into output color data in a predetermined different format, the recording medium comprising: color conversion profile referring program code means for referring to a color conversion profile so as to convert the CMYK data into the output color data, the color conversion profile being created by a color conversion profile creating device including: a CMYK data generation unit generating the CMYK data; a colorimetric value converting unit converting said CMYK data generated by said CMYK data generation unit into a colorimetric value to be measured with respect to an image formed from said CMYK data by an image forming device; a black-character color judging unit judging whether or not said CMYK data generated by said CMYK data generation unit represents a black-character color; a colorimetric value correcting unit correcting said colorimetric value by performing a contrast correction appropriate for a black-character color to the colorimetric value converted by said colorimetric value converting unit from the CMYK data judged to represent the black-character color by said black-character color judging unit, and by performing a contrast correction appropriate for a non-black-character color to the colorimetric value converted by said colorimetric value converting unit from the CMYK data judged to represent the non-black-character color by said black-character color judging unit; and a color conversion profile setting unit setting said color conversion profile by using said colorimetric value corrected by said colorimetric value correcting unit, wherein said color conversion profile has a characteristic of emphasizing a contrast of the output color data corresponding to the CMYK data representing the black-character color more than a contrast of the output color data corresponding to the CMYK data representing the non-black-character color.
