For color evaluation, we use two different methods: visual assessment and colorimetric measurement.

The visual assessment is carried out in a standardized light cabin, where our trained staff evaluate the samples using a gray scale (ISO 105-A02).

For colorimetric evaluation, we use measuring devices with various observer angles and light sources:

One device uses diffuse light (d/8° sphere geometry), and another uses a 45/0° measurement geometry.

Additionally, these devices allow us to determine the gloss level at a 60° angle.
