Compensating Printer Modulation Transfer Function in Spatial and Color Adaptive Rendering Workflows

Experiments have shown that the quality of printed images depends on the capacity of the printing system to accurately re- produce details. We propose to improve the quality by compensat- ing for the Modulation Transfer Function (MTF) of the printing system. The MTF of the printing system is measured using a mod- ified version of the method proposed by Jang and Allebach [1]. Then the MTF is adaptively compensated in the Fourier domain, depending on the frequency and on the local mean value. This compensation is included within our mathematical framework for Spatial and Color Adaptive Gamut Mapping Algorithms. Results of a category judgment experiment show significant improvement as the printed MTF compensated images obtain the best scores.
