video: How to Measure Gloss using the Elcometer 480 Glossmeter

Choosing the Correct Angle for Gloss Measurement:

Gloss measurement is based on the amount of light reflected on the surface relative to a polished glass reference standard, measured in Gloss Units (GU).

The amount of light that is reflected on the surface is dependent on the angle of incidence and the properties of the surface.

Gloss is categorized as either matt, semi or high gloss. In order to determine the most appropriate measurement angle start with a gloss meter set at 60degree angle of incidence.

If the result is between 10-70GU, the coating is termed ‘semi-gloss’ and should be measured using the 60degree angle.

If the result is less than 10GU, the product is ‘low gloss’ and should be measured using the 85degree angle and if it is greater than 70GU,

the product is known as ‘high gloss’ and should be measured using the 20degree angle.

Gloss Range	60° value	Measure with
High Gloss	> 70GU	20°
Semi Gloss	10 - 70GU	60°
Low / Matt	< 10GU	85°
