Abstract
A color chart is for performing color adjustment on an image forming apparatus. The color chart includes identification information and a color adjustment patch. The identification information is on an image forming apparatus to which color adjustment is to be applied. The color adjustment patch includes a plurality of color patches for performing color adjustment on the image forming apparatus indicated by the identification information.
Claims19
A color chart for performing color adjustment of an image forming apparatus, the color chart comprising:
- identification information of an image forming apparatus to which color adjustment is to be applied, the identification information included in a color code including
- a plurality of first color patches of a plurality of colors, and
- second color patches of fixed colors at both ends of the color code in a color patch arrangement direction;
- a color adjustment patch including a plurality of third color patches for performing color adjustment on the image forming apparatus indicated by the identification information;
- and
- a plurality of determination patches, each determination patch of the plurality of determination patches including a color patch for determining presence or absence of in-plane unevenness in the color chart and each determination patch being adjacent to neither a portion of white paper of the color chart nor a white color patch,
- wherein the color adjustment patch and the determination patch are arranged at mutually independent positions.
