• The flux I_0 reflected at specular angles 45°-45° from the surface of glossy paper and the assumed value of its diffuse component I_2 defined experimentally are measured with a goniophotometer. The ratio of I_0 to I_2 is taken as a measure of gloss, and denoted by G_<NF> according to an earlier paper of E. Fukushima. For a series of machine glazed papers differing considerably in colour, the values of C_<NF> are compared with the visual gradings of 36 Japanese observers, and a linear correlation of the logarithm of G_<NF> with the visual gloss is found with a correlation coefficient +0.986 except for two papers. The method of determining the value of I_2 is also introduced and the voting distributions of the observers for the gloss of the papers are discussed.
