CALIBRATION SYSTEM, CALIBRATION METHOD, AND RECORDING MEDIUM FOR COORDINATING COLOR VALUE OF OUTPUT COLOR OF ONE IMAGE FORMING APPARATUS WITH COLOR VALUE OF OUTPUT COLOR OF ANOTHER IMAGE FORMING APPARATUS
CALIBRATION SYSTEM, CALIBRATION METHOD, AND RECORDING MEDIUM FOR COORDINATING COLOR VALUE OF OUTPUT COLOR OF ONE IMAGE FORMING APPARATUS WITH COLOR VALUE OF OUTPUT COLOR OF ANOTHER IMAGE FORMING APPARATUS
A calibration system includes a photographing device, a first image forming apparatus, a second image forming apparatus, and a tone-characteristics correcting circuit. The first image forming apparatus prints a first chart including patches in a plurality of colors. The second image forming apparatus prints a second chart corresponding to the first chart. The tone-characteristics correcting circuit corrects tone characteristics of the first image forming apparatus. The tone-characteristics correcting circuit corrects the tone characteristics of the first image forming apparatus to tone characteristics of the second image forming apparatus based on a difference in color value of patches between the first chart and the second chart in a both-side print chart image generated such that the first chart and the second chart are simultaneously photographed by the photographing device.
