A color reproduction system with drift correction that includes a storage module, an image processing module, a printer, a scanner, and a calibration module. The storage module stores one or more current linear response halftones and a set of device independent color signals representative of a calibration target. The image processing module receives the stored device independent color signals and generates binary print data based on the one or more current linear response halftones. The printer prints a copy of the calibration target in accordance with the binary print data. The scanner scans the copy of the calibration target printed by the printer to generate scanned image data that corresponds to the copy of the calibration target. The calibration module generates one or more tone response correction functions based on a comparison between the scanned image data and the stored device independent color signals representative of the calibration target, and creates one or more calibrated linear response halftones based on the generated tone response correction functions. In some instances, the one or more calibrated linear response halftones are stored in the storage module as the current linear response halftones.
