Can someone (graphic designer or printer?) explain to me CMYK vs RGB?

Printers only do CMYK – it stands for Cyan, Magenta, Yellow, and Black. These are typical printer ink colors (there are no RGB printers).
RGB is for monitors – Red, Green, Blue; it’s about light rather than ink.

The colors aren’t the same because ink mixing doesn’t work the same as light mixing. I.E. if you put all ink colors together you’d get black(ish), if you put all light colors together you get white light.

If you are designing on the computer, it’s important that your document (to be printed) is set to CMYK colors so they match up to the printer better. You can check this in the documents settings, and there are plenty of tutorials to learn how to change it in most graphic design programs. An RGB document will not print quite the same from a printer – the colors are often muddier.

Can you get a sample invitation to make sure the colors come out right?
I mean a phyicial invite – not a screen shot of what it’s going to look like.
What you get at home will MOST LIKELY be similar to their printers (since all printers do CMYK) but with such an expensive project it’s better to be safe and get a printed sample than be sorry.

Yes, the difference is will you be looking at the image on paper or on a screen. CMYK is for paper. RGB is for computer screens.

@StL.Ashley:  While all printers print CMYK – home printers ONLY have black (why K = Black i don’t know) wheras professional printers (like the one I have at my office) had MK, PK and G (Matte Black, Photo Black, and Grey) so we have 6 ink cartridges instead of 4 making the mix much more precise.

I would go with the CMYK code that you were given and then ask C&P to do a test print for you!
