Gloss measurement – high gloss to matt gloss
In gloss measurement, a gloss meter measures the mirror reflection. The light intensity is registered over a small range of the reflection angle.
Gloss measurement
Gloss is a visual impression that depends on the surface texture.
The more direct light is reflected, the greater the impression of gloss.
A gloss meter measures the mirror reflection. The light intensity is registered over a small range of the reflection angle.
The angle at which the light is incident is equal to the angle of reflection.
Gloss ranges - high gloss to matt gloss
In order to obtain a clear differentiation over the entire measuring range from high gloss to matt, three different measuring ranges were defined.
| Gloss area | 60° value | to be measured with |
|---|---|---|
| Medium gloss | 10 to 70 | 60° Geometry |
| High gloss | >70 | 20° Geometry |
| Matt gloss | <10 | 85° Geometry |
Application
