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
First Claim
1. A calibration system, comprising:
- an photographing device;
a first image forming apparatus that prints a first chart including patches in a plurality of colors;
a second image forming apparatus that prints a second chart corresponding to the first chart; and
a tone-characteristics correcting circuit that corrects tone characteristics of the first image forming apparatus,wherein 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.

Abstract
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.

3. A calibration method comprising:
-
printing a first chart including patches in a plurality of colors by a first image forming apparatus; printing a second chart corresponding to the first chart by a second image forming apparatus; and correcting tone characteristics of the first image forming apparatus, wherein the correcting includes correcting 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 printed by the first chart printing and the second chart printed by the second chart printing are simultaneously photographed by an photographing device.

4. An image forming apparatus for printing a first chart including patches in a plurality of colors, the image forming apparatus comprising
a tone-characteristics correcting circuit that corrects tone characteristics of the image forming apparatus, wherein the tone-characteristics correcting circuit corrects the tone characteristics of the image forming apparatus to tone characteristics of another image forming apparatus based on a difference in color value of patches between the first chart and a second chart in a both-side print chart image, the second chart being printed by the other image forming apparatus corresponding to the first chart, the both-side print chart image being generated such that the first chart and the second chart are simultaneously photographed by an photographing device.
-
5. A non-transitory computer-readable recording medium on which is recorded a calibration program executed by an image forming apparatus that prints a first chart including patches in a plurality of colors, the calibration program causing the image forming apparatus to function as
a tone-characteristics correcting circuit that corrects tone characteristics of the image forming apparatus, wherein the tone-characteristics correcting circuit corrects the tone characteristics of the image forming apparatus to tone characteristics of another image forming apparatus based on a difference in color value of patches between the first chart and a second chart in a both-side print chart image, the second chart being printed by the other image forming apparatus corresponding to the first chart, the both-side print chart image being generated such that the first chart and the second chart are simultaneously photographed by an photographing device.
