[RGB(0,0,255) in CMYK]

How then does versaworks take my RBG image and make it come out the exact same way on the printer.  That indicates it is possible at some level in some way.

[RGB(0,0,255) in CMYK]

I create an RGB/8 document and make a square that is RGB(0,0,255).  That's the exact colour I want to see.

How do I make the EXACT same colour in CMYK??????????  I use all kinds of online tools where you put in RGB and it spits out CMYK and put those values in and never comes out like I want.  The should not be difficult.  Someone show me simple, step by step please.  I've read all the stuff about why it's different blah, blah, blah.  Yea.  Just help me fix it please.
