Gloss is the opti­cal proper­ty of a sur­face to reflect light into the specu­lar direction, an important appear­ance factor. The visual impres­sion of gloss is depen­dent on the individual per­ception, there­fore the gloss values are deter­mined using gloss­meter. A Glossmeter directs a light at a specific angle to the test surface and simultaneously measures the amount of (specular) reflection.
