Description

Multi-angle color and effect measurement with the BYK-mac i
Traditional 5-angle color measurement calculates color values
by averaging the spectral reflection over the entire illuminated
spot and therefore can not differentiate between the color of the
basecoat and the reflection of the aluminum flakes. As a consequence,
two effect finishes can have the same color values with
a 5-angle spectrophotometer, but visually appear very different.
The visual difference is a result of the flake effects.

To characterize the impression of effect finishes under different
viewing angles and illumination conditions, the BYK-mac i spectrophotometer objectively measures the total color impression:
■ Multi-angle color measurement (6-angles) clearly defines the
light-dark as well as color flop behavior of effect finishes
■ Sparkling and Graininess control with a high resolution CCD
camera simulates effect changes under direct and diffuse lighting conditions
