- Abstract
Abstract In this article, the authors reproduce gloss unevenness on a paper surface by expanding the Torrance-Sparrow model, which is based on the measurement and analysis of mesoscopic facets on paper. As the conventional Torrance-Sparrow model only considers macroscopic and microscopic facets, the authors expand the model to be able to consider mesoscopic facets. The normal vectors of mesoscopic facets on a paper surface were measured by using a collimator lens system with a small pinhole aperture, and the authors obtained the normal vector map by moving the stage for the paper. Gloss unevenness was reproduced by generating the same probability distribution as the measured distribution of the normal vectors. As a result, the authors succeeded in reproducing gloss unevenness using an expanded Torrance-Sparrow model.
