Abstract
A chart creation method to be used in a system including an image forming apparatus and a control apparatus, the control apparatus and a non-transitory computer-readable medium storing a chart creation control program are provided. The chart creation method includes: creating a print image of a chart; giving instructions to the image forming apparatus to print the chart and measure colors of the chart; obtaining measured color values of the color patches of the chart from the image forming apparatus; and rearranging the color patches of the chart so as to restrict spread of average color values of subgroups of color patches in the chart within a predetermined range. The chart creation method further includes: creating a print image of the color chart including the rearranged color patches, and giving instructions to the image forming apparatus to print the chart and measure colors of the chart.
