What is CMYK and what is RGB?
The CMYK color model stands for Cyan, Magenta, Yellow and blacK. When a color photo is printed it is literally separated into these four colors and printed one color at a time. These four colors then combine to give you the full color image.
When a photograph is going to be reproduced on a traditional printing press or on today’s digital presses or color printers, photos should be converted to CMYK format prior to reproduction to ensure color accuracy.
The RGB color model stands for Red, Green and Blue. Files in RGB format are intended for use on electronic systems like TVs, mobile phone displays and computer monitors.
You’ve probably noticed that the colors of photos on different electronic devices often look different—that is because each device reads the color breakdowns differently. You don’t want this type of inconsistency in print.
