Glossmeter Applications And Uses - Quality Control For The Automobile And Printing Industries

To measure whether gloss has disintegrated and to measure gloss application, a glossmeter is a necessary instrument. Glossmeter devices measure the shine or specular reflection of a surface, measuring the intensity of light reflected from an object or material over a range of reflected angles. Different colors and different materials have different gloss levels, some absorb more light than others. Metal surfaces typically reflect more light over a larger angle compared to non-metal materials.

Specular reflection is light reflected from a surface—light coming from one direction is reflected off the surface of liquid or material, at a defined outgoing direction. Specular reflection differs from diffuse reflection, the latter occurring when light is diffused in a range of direction. The difference between specular and diffuse reflection is evident when you compare gloss and matte paints—gloss paint gives off specular and diffused reflection whereas matte only reflects diffused light.
