Thanks for the advice! Semiprofessional, at any rate. It's something I've wanted to dabble in for many years, but never took seriously enough to do something about. I guess I want to work with a printer who can do the proofing for me. And that I should make an entry in my budget for a set of those Pantone books.

So I don't have to worry about temperature or relative RGB values, only brightness? The perceived brightness would of course depend on the lighting in the room too, nearly impossible to keep consistent. But I still haven't noticed a single dead pixel, something I believe this display was praised for back in the day.
