Which gloss meter angle should I use for my application?
Gloss is measured in gloss units (GU) and is traceable to reference standards held at NIST.
High Gloss: 20°
The acute measurement angle of 20° gives improved resolution for high gloss surfaces. Surfaces that measure 70GU and above at the standard angle of 60° 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°
All gloss levels can be measured using the standard measurement angle of 60°. This is used as the reference angle with the complimentary angles of 85° and 20° often used for low and high gloss levels respectively.
Low Gloss: 85°
For improved resolution of low gloss a grazing angle of 85° is used to measure the surface. This angle is recommended for surfaces which measure less than 10GU when measured at 60º.
This angle also has a larger measurement spot which will average out differences in the gloss of textured or slightly uneven surfaces.
Why measure Haze?
For polished metal surfaces haze is often associated with polishing marks or chemical residue.
Reflection haze is an optical phenomenon usually associated with high gloss surfaces.
It is a common surface fault that reduces appearance quality.
A hazy surface has a visibly shallower reflection with a milky finish and halos appear around reflections of strong light sources.
A high gloss finish with haze exhibits a milky finish with low reflective contrast- reflected highlights and lowlights are less pronounced.
On surfaces with haze, halos are visible around the reflections of strong light sources.
Causes of Haze
• Pigment properties
• Particle size
• Binder compatibility
• Influence and migration of additives
• Resin types and quality
• Drying conditions
• Cure temperature
• Polishing marks
• Ageing and oxidisation
