ABSTRACT:
A printing device is requested to generate a calibration test print. The printer generates a plurality of color patches and identification data which are put in hard copy form by a marker. The identification data includes data such as device identifiers, calibration print identifiers, and calibration statistics for the printing device. The hard copy calibration print is scanned and is transmitted to a calibration server. The calibration server interprets the coded data and determines the originating device, the calibration pattern printed, and an optimal color pattern based on the identification data. The color pattern printed is then compared to the optimal color pattern and their differences are determined. A color correction table is generated based on the differences and transmitted to the network address of the originating printer based on the identification data. The identification data provides for automatic recalibration of printing devices on a network.
