You get better colour reproduction from CMYK than RGB.

CMYK is a cheaper option for Ink colors and has been the standard practice for years. RGB is the colors you view on screens, such as televisions or computer moniters. They are 2 totally different ways of color management. CMYK produces less colors than RGB.

Tuila is correct.
CMYK is for printing a job on a printing press, unless its spot colors (1 or 2 colors, usually PMS colors - PMS = Pantone Matching System), but thats another story.
RGB is for looking at it on your desktop monitor, and printing on the $40 inkjet printer on your desktop.
It is virtually impossible to get the 2 to match exactly.
RGB has a wider color spectrum, blues are bluer, reds are redder, etc. But they cover each other up when printed on top of each other, and produce a kinda of muddy dirty brown. Where as CMYK inks are (for lack of a better word) transparent, and the blend together, yellow and cyan make green, etc.
We get customers who design jobs for their company in Powerpoint (which is RGB, and a VERY POOR choice for doing design work), then print it out on their $40 desktop inkjet, and then when we convert it to 4 color process (CMYK) to print on our $1.5 million dollar printing press, they complain because "it doesnt match my copy!" Its not going to!
Basically, RGB, and CMYK are 2 entirely different animals.
CMYK is for printing, and RGB is for looking at!

It allows for wider variety of colours to be achived and a lot more combinations. RGB is pretty basic
