Mike
thank you for indepth reply to my questions.
At this moment my process of maintaining the color with supplier rely on sending them first our proprietary color sample and then comparing/evalauting what they ship to me in exchange. Unfortunately, this takes too long and never let me get expected results.
As I understood it right best approach would be to order plastic color specimens, i.e in Xrite(suppose simultaneusly they deliver specification like Lab), and deliver it to supplier or best to compound factory which then create extra material according to specification and then ship it to supplier?
But, this works best for big volume orders, I am afraid.
Proper light booth sounds as reasonable idea, contrary to Xrite spectometers, which at this moment are way too expensive to me.
Have you got any experience with less sophisticated devices, thus cheaper like Pantone Capsure?
