BYK-mac i MetallicColor

Color & Effect measurement of metallics and pearls

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 i spectrophotometer 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°
  • Additonal color measurement behind the gloss for color travel of interference pigments: -15°
  • Sparkle and graininess measurement for flake characterization

Accurate results and low maintenance

The BYK-mac i spectrophotometer uses a LED light source with longterm stability and patented illumination control which provides superior accuracy and low maintenance for many years.


  • 10 year warranty on the LEDs - no lamp changes needed
  • Stable, long-term calibration - needed only every three months
  • Temperature stable between 10 - 40 °C - without calibration
  • Excellent agreement between instruments allowing usage of digital standards among the supply chain

Reliable readings at any time

In order to guarantee stable positioning, the BYK-mac i is equipped with trigger pins on the bottom plate of the instrument. If the pins do not have contact with the surface, an error message will be displayed. This ensures reproducible results on test panels as well as curved parts (r > 500 mm).
Additionally, the surface temperature is measured and saved with each measurement.


Color tolerancing - a challenging task

Each company is using their specific tolerances for the different colors.
In the last years weighted color 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.
Color tolerancing - easy to master with BYK-Gardner!


Quantification of Fluorescent Light

The BYK-mac i informs you of the color's light fastness. The instrument is equipped with additional sensors to detect fluorescent light excited in the visible range.

A new index, the Intensity Emission value, quantifies the fluorescent light and can be used for new color development as well as for batch-to-batch control.

Color Control of small and curved parts

Color harmony between small parts like headlamp cleaning device covers or distance sensor covers integrated in larger components is especially critical.

To ensure repeatable results even on such products, the BYK-mac i 12 mm offers you a much smaller measurement area as the regular BYK-mac i - only 1/3 of the area.
