ABSTRACT:
A calibration precision evaluating apparatus includes a calibrator carrying out calibration to adjust an ink amount output characteristic so that a measured color value is approximated to a reference value, a confirmation patch maker printing plural confirmation patches including a background patch and having the known reference values corresponding to the confirmation patches, a color measurer color-measuring the confirmation patches, acquiring initial color measured values, a background color shift amount calculator calculating a first amount of background color shift between the reference values and the initial color measured values with respect to the background patches, a corrector correcting the initial color measured values based on the background color shift amounts, acquiring corrected color measured values, and a precision evaluator carrying out precision evaluation of the calibration based on a second amount of color shift between the corrected color measured values and the reference values with respect to the confirmation patches.
