摘要

For consistent color reproduction, a digital printer must operate in a stable mode. However, due to uncertainties such as changes in humidity and temperature, color printers drift over time. Calibration is an approach that can be used to bring back the printer to its initial state from a drifted state. Different algorithms are used to calibrate printers. Among them are one-dimensional gray balance, one-dimensional channelwise linearization, two-dimensional calibration, and three-dimensional calibration. In this paper, we benchmark the performance of different calibration algorithms in stabilization of digital color printers subject to printer drift. The figure of merit used for comparison is the improvement in CIELAB ΔE between the output of calibrated machine and the output of the machine in a drifted mode for the same input. We also examine the optimum number of color patches needed to be measured for calibrating the machine with different calibration algorithms. The optimum number of patches is selected using dynamic optimization algorithm. Simulation results are presented using real printer data.
