Neugebauer reflectance model of frequency modulation halftone image

摘要

Based on the ink spreading enhanced Yule-Nielsen modified spectral Neugebauer model, the reflectance spectral prediction model of frequency modulation halftone image is developed by using a weighting factor to signify the correlation proportion of dot-on-dot and random dot mixing screening. Our results shown that in the ink jet printing, the mean ΔE difference between measured and predicted values are 2.64, smaller than the dot-on-dot model and Demichel model, which are 4.31 and 3.45.
