Sure! A tool like Basiccolor Improve or Colorlogic ANT can help in averaging, correcting and smoothing the measures. I’m planning to measure at least 4 times, each target rotated in 90 degrees.
The customer didn’t choose the fabric yet. Would you guys point me examples of “paper-like” fabrics to make the color management job easier?
Best Regards,
Lorenzo
