Comparison of 1-D, 2-D and 3-D Printer Calibration Algorithms with Printer Drift
Abstract: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.

For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.
Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
