Abstract

Gloss is one of the important factors in quality of printed paper. Gloss unevenness occurring on the paper surface affects to evaluate the quality, and it is difficult to be reproduced by the Torrance-Sparrow model because the model considers only macroscopic and microscopic facets. In this paper, we reproduce the gloss unevenness on the paper surface by expanding the Torrance-Sparrow model to consider mesoscopic facets. Normal vectors of the mesoscopic facets on the paper surface were measured, and the gloss unevenness was reproduced by generating the same probability distribution to the measured distribution of the normal vectors. As a result, we could reproduce the gloss unevenness by the expanded Torrance-Sparrow model.
