Principle
GLOSS (GLOSS) – measuring the percentage of the number of reflflected light. Reflflection fog shadow (HAZE) – due to bad coating pigment dispersion in the microstructure of emulsion appearance, will happen this optical effffect known as fog.Phenomenon: fog fifilm is high gloss surface characteristic of the phenomenon. Tiny grain of high gloss surface near the main produce low intensity in the direction of the reflflected light scattering light, but much of the incident light in the mirror reflflection, makes the surface seems to be high gloss and image quality, but the images have a milky mist. The lower the fog shadow reading, surface quality, the better.
