CMYK COLOR

CMYK is used in commercial printing, and splits an image into cyan, magenta, yellow, and key (black), which represent the inks mixed on the press to create any other color. Most images designed to be viewed on a screen are RGB, which uses a mixture of red, green, and blue light, to achieve the same effect. Monitors, which operate in RGB, don’t always accurately represent CMYK colors, especially where reds are concerned, but a system of color profiles and screen calibrators means colors can be kept consistent across screens and on to the press. We’ve only used CMYK here, because it made one step easier—you’ll want to convert back to RGB before you finish, and not just because CMYK files can be significantly larger than RGB ones.
