We measure gloss in gloss units (GU) and is traceable to reference standards held at NIST (Germany), NRC (Canada) or NPL (UK).

High Gloss: 20° The acute measurement angle of 20° gives better resolution for high gloss surfaces. Surfaces that measure at 70GU and above at the standard 60° angle are often measured with this geometry. The 20° angle is more sensitive to haze effects that affect the appearance of a surface.

Universal Measurement Angle: 60° Every gloss level can be measured using the standard measurement angle of 60°. This is the reference angle with complementary angles of 85° and 20° often used for high and low gloss levels respectively.

Low Gloss: 85° For enhanced resolution of low gloss a grazing angle of 85° is used to measure the surface. This angle is proposed for surfaces which measure less than 10GU when measured at 60°. This angle also has a greater measurement spot which will average out differences in the gloss of textured or slightly uneven surfaces.

For polished metal surfaces, haze is often associated with chemical residue or polishing marks

Reflection haze is an optical phenomenon normally associated with high gloss surfaces. It is a usual surface fault that reduces appearance quality. A hazy surface has a visibly shallower reflection accompanied by a milky finish and halos that appear around reflections of strong light sources.

No Haze, deep reflection

High Haze, shallow finish

A high gloss finish alongside haze exhibits a milky finish with low reflective contrast- reflected lowlights and highlights are less pronounced.

Low Haze

Higher Haze

On surfaces with haze, halos are visible around the reflections of strong light sources.

• Dispersion
• Pigment properties
• Particle size
• Binder compatibility
• Influence and migration of additives
• Resin types and quality

Curing

• Drying conditions
• Cure temperature

Post Coating

• Polishing marks
• Cleanliness
• Ageing and oxidisation Haze- Often visible as a milky finish on high gloss surfaces.
