General rule of thumb, since I also colour comics professionally, the final print will NEVER look like what you've got on the monitor. Here's a title I'm currently working on - http://www.red5comics.com/?cat=9
In comics, once colourists finishes their pages, it's out of their hands. The editor may choose to tweak the final product, throw it off to the letterer, then drop off a pdf to the printers once that's done. Considering deadlines there isn't much time if any at all to do any proofing, so the quality on the final print can change further. I can calibrate my monitor settings all I want when I'm working on pages, but it's all a moot point if the publisher suddenly switches printing companies and I have to start over again.
Red 5 used to print stuff in China, now they're doing it in Canada with Quebecor, one of the worst places I can think of for any comic to be printed. The cover paper stock is the same as the interiors and it feels like grease in your hands.
If you've got a solid printer at home like an Epson you can adjust your settings all you want on the fly, but if you're working with local printing companies [private or otherwise] then it's usually best if you're personally there to watch the process. Look through the proofs and give direction.
