Ok guys, forgive me if this question is somewhat vague. I'm neither a pressman nor a prepress guy. But I'm not completely ignorant either!
Anyway, we are experiencing visible variation in a job we print regularly. PMS 283 I think? It is "blue". Solids only (100%, no screens). The dry density will read the same on two sheets from two separate runs but you can see a distinct difference.
Same plates, same press units, sometimes the same ink lot, other times not (we don't mix our own).
Other than variation in the ink and paper supplied by our vendors, what should we be looking at?
Is dot gain an important factor here if we're just printing solids? Other mechanical/press issues?
Now that I think about it, maybe this doesn't really belong under color management
Thanks in advance for any suggestions.
