What you see isn't always what you get, particularly when it comes to printing photos. If you're not a photography professional, it may not be such a big deal if the shade of green you see onscreen isn't exactly the shade of green you see on the printed photo. But if you are a pro, or if that kind of things bothers you, you can always calibrate your printer, scanner, or monitor properly to ensure that what you see on the screen is what your print actually looks like. One way the pros do this is using ICC printer profiles, and sites like those from paper manufacturer Ilford provide guidance on how to match paper, color profiles, and printer settings to get the best results. How to Calibrate Printers and Scanners will give you first steps toward making the best possible printed results.
