<p>A color copying machine has a color correcting circuit. the color correcting circuit includes a device (21,56) for generating reference pattern data on each color, a device (3) 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 (3), a device (54) for measuring a color reproduction error based on the reference pattern data generated by the generating device (21,56) and the printed result of the reference pattern data read by the reading device, and a device (25,52) for calculating a color correction coefficient of each color based on the color reproduction error measured by the measuring means (54). <IMAGE></p> |
