PRODUCTS & PROCESSES
To determine the correct gloss measurement angle , gloss is first measured at a 60 ° angle :
If the result is between 10 – 70 GU , the object in question is considered semi-gloss and the 60 ° measurement angle is appropriate .
If the result is greater than 70 GU the surface is considered high gloss and should be measured with the 20 ° angle
If the result is less than 10 GU , the surface is considered matte and should be measured with the 85 ° angle .
The PosiTector GLS Gloss Meter is available in three models :
PosiTector GLS 60 ° for measuring most gloss applications and is the preferred angle for semi-gloss
PosiTector GLS 20 °/ 60 ° for measuring high-gloss to semi-gloss , and calculating Haze Index
PosiTector GLS 20 °/ 60 °/ 85 ° for measuring high- , semi- , and matte gloss levels and also calculating Haze
