How does a gloss meter work
http://www.gloss-meter.info/glossmeter-function.html WebOct 16, 2024 · The gloss meter projects an incident light onto the surface. At an equal but opposite angle, the gloss meter measures the amount of reflected light. Typically, in industry, three angles are used to measure gloss, depending on the gloss level desired. High-gloss surfaces with a GU of 70 or above should be measured using a 20° gloss meter.
