@Griffin I think there's something to this, because I normally work with the brightness on my screen at a one or two and don't have to fiddle with an image too much for it to print accurately.
However, I still have to fiddle with it! When I edit files for print, I up the brightness by 5 - 10%, and I've found that after doing that, prints are pretty accurate.
I recommend doing a test run if you have a desktop printer, and if the printer you're ordering prints from offers it, a physical proof. The proof is really the only way to accurately determine the print quality, as there are so many factors that have an effect on the outcome: the colors you're using (will the light-based pixels accurately transfer over to ink-based printing?), how your screen displays color (every screen is a little --or a lot--different, depending on how it's calibrated), how the printer's screen displays color, the color profile you're using, the color profile the printer uses, the printer that the printer uses, the variation of colors and pigments in inks, etc.
Since there are variables you can control and a lot of variables you can't control, my strategy is to get as close as I can to how I intend the image to print, check the proof, and then accept that it still might not turn out as planned. Big variations, yes, those should be corrected at the proof stage. But small variations will happen. I don't sweat those small variations ... overall, the image will still look good and the only one who will even notice the difference is me.
So that's my approach, anyway, good or bad or in between. Hope it helps!
