Color control is crital in the production process.
In Alcoat, we carry out strict color control before and during the production process.
The color difference between a reference and a sample is determined by the deviation on the different axes △L*,△a*,△b*, and we take into account the total color difference. Apart from that , color difference will also be measured from 2 physical samples.
What’s more, we are able to control the color difference in a previously produced batch in the smallest range using both △E categories and visual comparison.
