Abstract
Patches (standard images) are printed on a printing medium with a standard ink recording quantity with a printer (printing device)filled with alternative ink different from corresponding inks. The printed patches are subjected to colorimetry in the Lab color space (predetermined color space) to acquire alternative colorimetry data. The acquired alternative colorimetry data is converted into predictive colorimetry data obtained when patches are printed on a printing medium with the standard ink recording quantity with the printerfilled with the corresponding inks and subjected to colorimetry in the Lab color space. ID (error information) that represents the result of correlation between the predictive colorimetry data obtained by the conversion and predetermined reference colorimetry data is acquired.
