A particularly crucial aspect in the product processing is the quality control. All pigments, from raw materials to finished products do undergo in the following systematic quality tests, which vary depending on the application method:

Quality control:
(1) Raw materials testing
(2) Production process control
(3) Application testing

All pigments, according to the very strict controls they undergo, absolutely have to be conform, otherwise they are rejected. This approach is implemented in the ISO 9001:2000 context.
