- Structure size
The waviness of automotive paints is in a range of approx. 0.1 to 30 mm wavelength. These phenomena are often visually evaluated and subjective terms like degree of peel or texture are used as descriptions. Orange peel can be seen on high gloss surfaces as a wavy pattern of light and dark areas. Depending on the slope of the structure element the light is reflected in various irections.
Only the elements reflecting the light in the direction of our eyes are perceived as light areas.
- Observing distance
- Resolution of our eyes
The resolvable structure size is also dependent on the observing distance. Very fine structures that are below the human eye's resolution (approx. 0.1 mm) can no longer be recognized as a light / dark pattern, even at a close distance. The result is a reduction of the image forming quality (IFQ). At 3 m distance, structures between 1 – 3 mm can hardly be resolved as a waviness
but influence the appearance.
