ABSTRACT:
A color copying machine has a color correcting circuit. The color correcting circuit includes a device for generating reference pattern data on each color, a device for printing the reference pattern data generated by the generating device, a device for reading a printed result of the reference pattern data printed by the printing device, a device for measuring a color reproduction error based on the reference pattern data generated by the generating device and the printed result of the reference pattern data read by the reading device, and a device for calculating a color correction coefficient of each color based on the color reproduction error measured by the measuring device.
