Similar issues that can arise.
Issue 1:
I know of a company that uses a lot of filters that translate great on screen, but the 4 different artist all have a different monitor and all work on the same projects at the same time to complete jobs faster. Groups of four designs for example. Then they flatten these and save as jpgs. Answer, Each artist should complete their own group and not mix it up so all jobs stay consistent.
Issue 2:
They send out jpg's to the sales rep. We found out that the Sales rep is showing the designs on his lap top. Never printing them out for fear of someone stealing his designs he's selling. (it's happened before) So his monitor is rich in color and has deep shadows.
Issue 2:
The separator has a completely different monitor and gamma setup that also has a wider color gamut and more vibrant. So when she separates, she's separating (how she sees the art) and it comes out differently than from the original.
End result, customer approved based on what they saw on lap top screen and complains that it's not the same when they get the printed samples.
BAD PROCESS.
I made my suggestions, but they didn't change a thing.
