Total color impression of effect finishes
The appearance of effect finishes is influenced by different viewing angles and viewing conditions.
Apart from a light-dark flop and color shift special sparkling effects can be created.
The BYK-mac is unique as it measures both multi-angle
color and flake characterization in one portable device.
- Traditional 5-angle color measurement: 15° / 25° /
45° / 75° / 110°
- Additional color measurement behind the gloss for
color travel of interference pigments: -15°
- Sparkle and graininess measurement for flake
characterization
