i didn't know i had to use cmyk color for professional printing. why can't it be rgb color? will they convert the docs from rgb to cmyk color for me? if so, will the quality be reduced? because i notice when i convert any of my rgb color docs in photoshop to cmyk, there is noticeable reduction in quality - mostly, the colors seem to become less saturated and brilliant. i hope that won't be the case here.
the software does the conversion automatically. if you want a better idea of what your prints will turn out like, work in cmyk. there are some rgb colors that you see on screen that aren't reproducible on paper (out of gamut). color is tricky-- and some colors tend to shift more than others.
Your printer can convert from RGB to CMYK for you, but I always do it myself. Offset printing will be CMYK and if you want complete control, you'll need to create the CMYK file yourself (it just mutilates blues/purples, personally I can't stand CMYK).
You'll need to play with the vibrancy, saturation and other things to try to match the RGB file.
Also, if you want to get really accurate, you'll need the printer's printer color profile to get things more accurate (and possibly the specific profile for the paper type). PS has most of the more common printer's profiles installed.
Profiles can also make a HUGE difference in how things look.
If you are working with a pro printer, you can look at the proofs and they can adjust accordingly, but only within reason.
cmyk vs. rbg

yeah, lots of colors do. either photoshop 7.0 is out of whack or i'm going to have some screwed up looking prints

[pasted from your other thread]
yeah they're a pro printer and i'm sure they know what they're doing.
