# I used to do the in-house design work at a printers. Honest. I know I only post junk here.
When it comes to offset lithographic printing, it's REALLY important to understand the difference between CMYK and RGB.
One small example - when you convert from RGB to CMYK, the 'black' will be made up of all 4 colours, which can lead to all sorts of nightmares with registration.
And switching back and forth will make your colours all mushy and inaccurate.
Beware.
