CMYK and RGB colour formats relate to the way
pixels of colour are recorded. CMYK records intensities
of 4 colours: C-cyan, M-magenta, Y-yellow, K-key. "Key" is
just another word for black. RGB records R-red, G-green,
B-blue.
Printers require CMYK format for printing as it
relates directly to the actual inks used in the
the process.
All other technologies use RGB, which relates to
how computer screens display images. All computer
artwork can only be viewed and generated in RGB,
with a simple conversion required to CMYK for mass
production printing.
The average computer user will never need to get
involved with anything relating to CMYK. |
