Hi Showard,

Are you refering to colours on your screen that are printing out darker? The colours that appear on your screen are displayed using a different colour system and light source than those on a printed page, so naturally they will print darker.

If you mean the colours print out darker on press than from the proofing device you're using, then I suspect it is a colour management issue. Have you asked your printer for a color profile? Each time you use a different output device, you should apply a color profile that is calibrated for that device (printer).

I could explain this in more detail, but it might be easier to order my book, Exploring Digital Prepress

If you want to get seriously into colour management, here is another good resource:
