Photoshop: Convert RGB to CMYK

Converting an RGB image to CMYK using Photoshop

Photoshop allows you to edit your images in either RGB or CMYK "color spaces". When we generate light and color using a computer monitor, we use a combination of Red, Green and Blue (called "RGB") dots. When we print color images light is reflected off the image (not generated like a monitor does) and so a different set of colors are used. Printing presses use Cyan, Magenta, Yellow and Black (called "CMYK"). This is a "4-color process" that makes up the majority of printed material you see each day. If you're going to use your image on a website, you can work in RGB exclusively, but if you plan to print your final work, your RGB file must be converted to CMYK.
