I am doing some print work in photoshop, am i right in setting the colour mode to CMYK rather than RGB?

Also, does anyone know the differences in them for print, and anything about RGB to CMYK conversion?

Thanks

CMYK for print all the way, the colours used for printing are Cyan Magenta Yellow and Key (black for all intents and purposes) so it's important that you document is set to that colour mode. Some colours are only available in RGB (they have the little warning symbol next them in the colour mixer) and make sure you have a decently calibrateed monitor so that it displays the colour as close to the colour it will print as posssible - the best way to ensure the colours are correct is to use pantone references.

CMYK = for Cyan Magenta Yellow and Key (black) which are the four process ink colours used for litho press. RGB = Red Green Blue which are colours created by light. i.e your screen.

If you are creating artwork for any kind of printed material you will need work in CMYK. And don't JPEG compress the files - they won't print!

nything about RGB to CMYK conversion?

DON'T TRUST YOUR SCREEN !

The CMYK thing is generally true. However most of the top retouchers I know work in RGB for the wider colour range, then proceed with a CMYK conversion before printing (and I don't mean just switching the document colour mode).
