摘要

Gloss and clarity are essential factors for image quality, and several measurement devices and methods have been proposed for evaluating gloss perception. However, a device that can simultaneously measure the subjective gloss and clarity of printed materials has not yet been developed. Currently, to evaluate gloss and clarity, it is necessary to use separate measuring devices. The purpose of this article is to report the development of a simple evaluation method solving this problem. First, the features of the reflectance distribution that contribute to the gloss and clarity were extracted using a goniophotometer. They can be explained using the glossiness (gloss values) at both 20° and 60° angles. Next, a simple evaluation method based on the ratio and the difference of the gloss values was developed. Results from the proposed method exhibited good correlation with subjective evaluation scores. Because of its simplicity, the proposed method is expected to find widespread use in the printing industry.
