|Index|Description (Effect Finish module)|
|---|---|
| 60° |60° Gloss; overall specular reflectance level of the effect coating.|
|Waviness|Waviness of the effect finish, describing large‑scale distortion of reflections.|
|Graininess|Perceived coarseness or fineness of the metallic/effect flake structure in the coating.|
|Density (10°)|Number of visible sparkle points per 100 mm² area near 10°, indicating how densely flakes sparkle head‑on.|
|Area (10°)|Average sparkle size near 10°, describing the typical area of individual sparkle elements.|
|Brightness (10°)|Average luminance of sparkle points near 10°, describing how bright the sparkles appear head‑on.|
|Visibility (10°)|Average perceived brightness of sparkle elements near 10°, considering their visibility and the background colour of the material.|
|Density (45°)|Number of visible sparkle points per 100 mm² area at 45°, indicating flake activity at the side view.|
|Area (45°)|Average sparkle size at 45°, describing the typical area of individual sparkle elements off‑specular.|
|Brightness (45°)|Average luminance of sparkle points at 45°, describing perceived sparkle brightness from the side.|
|Visibility (45°)|Average perceived brightness of sparkle elements at 45°, considering their visibility and the background colour of the material.|
|SpR (10°)|Red‑channel sparkle intensity measured close to the viewing direction at 10°.|
|SpG (10°)|Green‑channel sparkle intensity measured close to the viewing direction at 10°.|
|SpB (10°)|Blue‑channel sparkle intensity measured close to the viewing direction at 10°.|
|SpR (45°)|Red‑channel sparkle intensity measured at the off‑specular 45° viewing direction.|
|SpG (45°)|Green‑channel sparkle intensity measured at the off‑specular 45° viewing direction.|
|SpB (45°)|Blue‑channel sparkle intensity measured at the off‑specular 45° viewing direction.|
|R|Average red‑channel surface colour of the effect finish (RGB).|
|G|Average green‑channel surface colour of the effect finish (RGB).|
|B|Average blue‑channel surface colour of the effect finish (RGB).|
