Abstract

We evaluate the best achievable performances of three different types of color printers, which follow the Neugebauer model, the Yule-Nielsen model and the Kubelka-Munk model. In an extensive optimization we calculate the best primary spectra that lead to a minimal average color error for a set of test spectra under a set of illuminations. The primary spectra are constrained to nonnegative values and a smooth characteristic. The results indicate a large potential to improve the current printer technique by only changing the ink characteristics. In addition it is shown that the Yule-Nielsen model, which is distinguished by consideration of dot gain, yields better results than the plain Neugebauer model. Both are surpassed by the Kubelka-Munk based model when appropriate primary spectra are used.
