Advanced Cellular YNSN Printer Model

An advanced cellular YNSN (Yule-Nielsen modified spectral Neugebauer) model is proposed in this paper. This new model is modified from the YNSN model and the cellular Neugebauer model to get more accuracy. There are two important concepts in the advanced cellular YNSN model. First, the entire CMY (cyan, magenta, yellow) color space is partitioned into 27 small subcells to improve the correlation between output colors and input signal. Second, the YNSN equation is modified by using a wavelength dependent function Ai(λ) instead of a wavelength independent function Ai used in the conventional YNSN model. In our experiments, 1134 patches were used to test the accuracy of our advanced cellular YNSN model and the conventional YNSN model, and we found that the average error of our advanced cellular YNSN model is 3.3 ΔEab which is more accurate than that of conventional YNSG model, 4.98 ΔEab.
