You miss my point, although yes, leave separation to us professionals if you don't understand what you're doing. Just as a side note - most printers simply use the (almost) default "U.S. Web Coated (SWOP) v2" separation parameters because they really don't know what they're otherwise doing. Old (read: analogue) prepress skills are mostly forgotten by most of todays printers. There are only a few of the old stalwarts still around that truly understand press colour. In saying this, when you think you're doing the right thing by handing your RGB to these guys, they generally know precious little more than you do when it comes to what the actual process does. Only major print shops have these skills any more.
What I was trying to impart is that
understanding CMYK is important in that the CMYK colour space is far less dynamic than RGB, and this must be considered by you when attempting to send your work in for print. If you want, or expect, bright pantone colour that your home printer might half deliver, you will be very sorely disappointed in what comes out on a web offset commercial press. If you understand the gamut range, at least, then your expectations might be at least in the ball park.
