GLOSS
Gloss is a measure of how much light is reflected from a sample surface at a defined angle.

AngleApplicationRange
20°High gloss finishes0 - 2000 GU
60°All gloss finishes0 - 1000 GU
85°Low gloss finishes0 - 199 GU

HAZE
Reflection haze is scattered light caused by micro texture and is measured adjacent to the main gloss component.

REFLECTED IMAGE QUALITY (RIQ)
RIQ is used to quantify effects such as orange peel and surface waviness. This new parameter gives higher resolution results compared to Distinctness of Image (DOI) measurement and better mimics human perception of surface texture, especially on high quality finishes such as automotive. Symptoms of poor RIQ: orange peel, brush marks, waviness or other structures visible on the surface. Reflected images are distorted.
Causes – Application problems, incorrect coating flow, coating viscosity too high/low, sag or flow of coating before curing, incorrect particle size/distribution, overspray, improper flash/recoat time, inter coat compatibility, incorrect cure times and cure temperature.

DISTINCTNESS OF IMAGE (DOI)
A measure of how clearly a reflected image will appear in a reflective surface.

PEAK SPECULAR REFLECTANCE (RSPEC)
RSpec is the peak reflectance measured over a very narrow angle. RSpec values are lower in surfaces with textures including orange peel and waviness. It can be used to identify subtle differences in smooth surfaces. RSpec is more sensitive to longer wavelength texture than DOI.
