What is Gloss?

high gloss

Gloss is a property of surfaces that involves specular reflection. Specular reflections are sharp beams of light produced by reflections from smooth, uniform surfaces. Gloss obeys the law of reflection, which states that when light is reflected from a surface, the angle of incidence is equal to the angle of reflection.

Reflections from smooth surfaces such as mirrors, cars, or calm bodies of water cause specular reflections. This reflection makes objects appear shiny or shiny, and it contributes to a glossy or mirror-like appearance.

semi-gloss or low-gloss

The appearance of an object is directly related to geometric conditions, namely the orientation of the light source and the observer. Take the glossy highlights of colored non-metallic objects as an example. Non-metallic objects appear to have white highlights. People don't look at the highlights of colored objects to see the color, but that's exactly where people see and measure gloss.

Semi-gloss to low-gloss is a property of surfaces that involves diffuse reflection rather than pure specular reflection. Diffuse reflection from a rough surface is the reflection of a collimated input beam that occurs in all directions, although in one direction, a specular orientation may be favored.
