Glossmeter have different kinds of measurement angles.Generally, 20° applies to High Gloss Materials, 60°applies to Medium Gloss Materials, 85° applies to LowGloss Materials. Two additional angles are used forother materials. An angle of 45° is specified for themeasurement of ceramics, films, textiles and anodisedaluminium, whilst 75° is specified for paper and printedmaterials.
