Abstract
A data correction subsystem for a color image processing system having a color image reading device and a color image printing device. A chart file is transmitted to the printing device so that the printing device produces a sample chart. Calibration data is calculated from read sample data so that the read sample data can be corrected to corresponding data in the chart file. The read sample data is obtained by causing the reading device to read the sample chart. Printing data to be transmitted to the printing device is corrected using the calibration data.
