Relative luminous reflectance factor

The relative luminous reflectance factor of a specimen at the specular direction. [Pg.2264]

Gloss is defined as the relative luminous reflectance factor of a specimen at the specular angle. Gloss is a function of the reflectance and the surface finish of a material, which, in turn, depends on the finish of the mould. [Pg.63]
