BYK-mac - Total Color Impression of Effect Coatings
BYK-Gardner – worldwide partner of the automotive, paint and plastic industries for quality control of color, appearance and physical properties - is introducing a new instrument to objectively characterize the total color impression of effect coatings: the BYK-mac.
Special effect coatings play a dominant role in automotive applications as they make an object distinctively appealing. In contrast to conventional solid colors, metallic finishes change their appearance with viewing angles and lighting conditions. Dependent on the flake type an additional sparkling effect is created which varies from sunlight to cloudy sky. These effects can no longer sufficiently be described with traditional multi-angle color measurement quantifying the diffused light reflections at 3 to 5 angles.
The new BYK-mac is unique as it objectively measures two parameters in one portable device:
- Flake characterization by measuring with a camera the visual impression of sparkling and graininess, simulating effect changes under direct and diffuse lighting conditions
- Multi-angle color measurement “before and behind the specular reflection” to give more information about the color travel of special effect finishes
