Claim One:
1. A profile creation apparatus comprising: a storage unit; a standard-color-profile obtaining section that obtains a standard color profile to be used for color conversion of input color values into color values defined according to standard colors; a reference-device-profile obtaining section that obtains a reference-device profile created by using measured color values of a printed matter obtained by printing of a first print image with a first printing device, the first print image being a print image on which color conversion was performed by using the standard color profile; a color-conversion-table creation section that creates a color conversion table to be used for color conversion of input color values into target color values, by combining the standard color profile and the reference-device profile, and stores the color conversion table in the storage unit; and a color conversion section that performs color conversion on a second print image to be printed by a second printing device, by using the color conversion table stored in the storage unit, and outputs to the second printing device the second print image on which the color conversion was performed, wherein the color-conversion-table creation section obtains the target color values to create the color conversion table by adding the standard color profile and the reference-device profile with being weighted by using a factor such that a weighed ratio of the standard color profile increases as chroma calculated from the input color values of the color conversion table increases, for values of the chroma which fall within a predetermined chroma region.
