Calibration apparatus for image forming apparatus, computer readable storage medium stored with program for calibration apparatus, and method for calibrating image forming apparatus
A calibration apparatus for an image forming apparatus includes a calculation unit for calculating a color deviation by subtracting a target value from each value on the two orthogonal axes not including brightness of a color coordinate system based on a measured color value of a printed material and a display unit for displaying the color deviation with respect to each gray balance at the feedback such that the number of times of inversions of a sign of the color deviation calculated by the calculation unit and a variation width of the color deviation when the sign of the color deviation is inverted can be detected.
