Measuring Geometry
Gloss is classed as either low, semi or high gloss. In order to determine
the best measuring geometry for your test start at a 60° angle as it is
considered the universal measurement angle.
The angle is selected based on the anticipated gloss range, as shown in
the table below.
Gloss Range
60° Value
Notes
High Gloss
>70 GU
If measurement exceeds 70 GU,
change test setup to 20°.
Medium Gloss
10 to 70 GU
Low Gloss
<10 GU
If measurement is less than 10 GU,
change test setup to 85°
