Summary :

The already reported physical glossiness such as Mirror glossiness, indistinctness-degree glossiness, etc. are not proportional to the psycological glossiness which is the standard of the gloss, in cases of various colored specimens. Thus, in order to obtain a glossiness proportional to the psycological glossiness, first, the brightness distribution of the colored specimens was measured. Then, it was transformed to bring the form of the measured brightness distribution close to the visual distinctness-begree distribution, by the expand-reduce transformation technique. From the transformed distribution curve, the new glossiness G(H, V, C) was defined as functions of hue H, lightness V, saturation C and the indistinctness-degree glossiness GID. This new glossiness G(H, V, C) was applied to the Munsell color atlas papers and the high glossy colored papers, and then it was confirmed to be in proportion to the psychological glossiness GPh.
