Effect Finish Module
Coatings with effect pigments exhibit sparkle and coarseness. Sparkle refers to a visual texture observed when mirror-like elements within a surface reflects light.
Measured Parameters

Coarseness
Coarseness describes the non-uniform grainy appearance of a surface when viewed in diffuse lighting conditions. Coarseness tends to increase with pigment loading.

Density
Sparkle density is a measure of the concentration of visible sparkle points on a surface when viewed under directional lighting conditions.

Colour
These values show the average RGB colour of the visible sparkles in the field of measurement.
Visibility
The Aesthetix® reports sparkle visibility; an average intensity value for any sparkling elements which have been identified as visible in the material.
Luminance
Aesthetix® displays surface average Y value from the CIE 1931 XYZ scale. This represents how light or dark the surface appears, independent of its hue or saturation.
Waviness
Waviness in surface finishes presents as a wavy texture resembling the peel of an orange.
Aesthetix® offers TAMS Waviness, PCI orange peel scale, and tension values to accurately characterise orange peel for various applications.
Haze
Haze refers to a cloudy or milky appearance on a coated or polished surface. Aesthetix® provides ASTM E430 compatible values and new perception based metrics which predict appearance in different viewing conditions (indoor vs outdoors).
In a car showroom, polishing defects in paintwork are barely visible, but in sources of bright natural light, halos are apparent.
Gloss
Set around the industry standard of 60 degrees, Aesthetix® gives gloss values complying to international standards with camera images to fully describe surface reflectivity.
