What is the difference between RGB and CMYK?
RGB refers to the primary colours of light, Red, Green and Blue that are used on your computer screen. CMYK refers to the primary colours of pigment: Cyan, Magenta, Yellow and Black. Many programs have the capability to convert the layout/images from the RGB to the CMYK. Quick Quality Printing requires that you convert your colours from RGB to CMYK.
Most computers give you the option of creating files in one of two color spaces: CMYK or RGB. CMYK stands for the four colors used for four-color process printing (cyan, magenta, yellow and black). RGB is the color space typically used on computer monitors and stands for red (R), green (G) and blue (B). RGB are the primary colors of light. Because CMYK is expressly designed for the four-color printing process, you must create your documents in this color space rather than RGB.
