RGB or CMYK?

So... I work in the Print media field. At my job I work and print exclusively in the CMYK color space. Everything I design eventually ends up on four color offset press. All Color ink jet printers are CMYK or CMY devices so it stands to reason that what's on the screen would more closely relate to the print if you work in CMYK color space. It seems that most digital users I have talked to are working in RGB. What are you working and printing in? What results are you getting? Good? Bad?

Thanks in advance for your comments.

I also work in a prepress environment. I print my own images at home on an Epson 1270. There are advantages to using RGB but if your final product is going to be output on conventional presses or is going to digital CMYK output you must work in the CMYK color space or you'll be sadly deceived by the appearance of the images on your monitor. RGB on screen is much more luminous and has a totally different appearance from anything you will ever be able to output on press. Greens, purples and oranges will drive you crazy because they look great in RGB on screen and look like mud on press.Don't try to cross the two color spaces for commercial output, you will be sorry

I agree with using RGB as your color model if you are printing on your inkjet printer. I am also in the offset press world, and I have tried printing CMYK on my Epson 1200 and I always go back to RGB for printing at home as they are richer and more vibrant. Just my opinion....

Guys,
IF you use PS color management and have calibrated your monitor, room light, viewing conditions for the final print, etc,
AND have profiles for your ultimate output device(s),
AND have set it as the destination space
THEN using the View ->Proof colors will show you on the screen what the output on paper will look like, no matter what output device you have ...
Quote : "you must work in the CMYK color space or you'll be sadly deceived" - I'd agree with this if you change the word "work" to "proof" as in the soft proofing above.
IF, however, you don't use color management, or don't use it properly, you'll frequently be sadly deceived

The Epsons are designed to accept RGB files and all the profiles I've seen assume that the document is an RGB image

gmaggelet, what profile did you use for your CMYK print on the 1200?
