Multi-angle Colour, Sparkle and Graininess Control
The appearance of effect finishes is influenced by different viewing angles and viewing conditions. Apart from a light-dark flop and colour shift special sparkling effects can be created. The BYK-mac i spectrophotometer is unique as it measures both multi-angle colour and flake characterization in one portable device.
- Traditional 5-angle colour measurement: 15° / 25° / 45° / 75° / 110°
- Additonal colour measurement behind the gloss for colour travel of interference pigments: -15°
- Sparkle and graininess measurement for flake characterization
Colour Tolerancing – a Challenging Task
Each company is using their specific tolerances for the different colours.
In the last years weighted colour equations were developed to achieve better agreement with our visual perception.
BYK-Gardner is your partner to guide you through the different methods and helps to set up your customer specific color difference method.
