What is Gloss ?

---

 Gloss is an aspect of the visual perception of objects.
 
Gloss is the attribute of surfaces that causes them to have shiny or lustrous, metallic or matte appearances.
 
Gloss is a visual impression that is caused when a surface is evaluated. The more direct light is reflected, the more obvious will be the impression of gloss.
 
Gloss effects are based on the interaction of light with the physical properties of the sample surface. The other influencing component is the physiological evaluation scale. The human eye is still the best tool to evaluate gloss differences. However, the visual surface control is insufficient, because evaluation conditions are not clearly defined, and people see and judge differently. In addition, the subjective perception of appearance is dependent on the personal experience: what is glossy for a paper manufacturer might be dull for an automotive maker. Gloss is measured by focusing on the reflected image and not by focusing on the surface. Eyesight and mood have a decisive role in the visual judgment. Also, important is what our eye is focused on. We evaluate a surface by focusing our eye on a reflected image of a light source. In order to guarantee a reliable and practical quality assurance it is necessary to define appearance with objective, measurable criteria. Accurate characterization of appearance does not only help to control quality, but improves quality and optimizes manufacturing processes.
 

High Gloss

---

Smooth and highly polished surfaces reflect images distinctly. The incident light is directly reflected on the surface, i.e. only in the main direction of reflection. The angle of incidence is equal to the angle of reflection.

Matte to Semi Gloss

---

On rough surfaces the light is diffusely scattered in all directions. The image forming qualities are diminished: A reflected object does no longer appear brilliant, but blurred.
The more uniform the light is scattered, the less intense is the reflection in the main direction and the duller the surface will appear.
