Hi all, first time poster here but I've been in the Screenprinting Industry 25+ years now.
My question is in regards to color validation. We've never done a good job of managing color in our Ink Department so it's my job to clean it up.
Our Quality Department suggested I work toward GPI Specifications of validating color via ∆E which I've tested on a few select jobs but the process is painstaking.
Does anyone here validate color beyond the standard eye approval process with a Light Booth? I'm interested moreso in instrumentational color matching such as measuring ∆E (CIE94 spec) with an Electro spectrophotometer.
Also, does anyone actually validate the straight colors coming from the Ink Supplier before introducing them into circulation?
