Additive Color (RGB) is created by mixing a number of different light colors. When you add up all of these colors, you create white light.

Subtractive Color (CYMK) is used to mask colors on a lighter background. The ink reduces the light that would be reflected off of your white paper. It subtracts brightness from white.

Pros of Working in RGB

• RGB offers a wider range of colors• There is more information stored with RGB files. The

printer has a better chance of matching these colors when printing.

• Once you convert to CMYK, you loose information in your colors and are no longer to gain that information back.

• RGB file sizes are about 25% smaller than CMYK• Images are web ready• Many filters and functions in Photoshop are only

available with RGB color profiles

• In order to keep as much information as possible, we will be working in adobe RGB and then converting profiles before printing.

• Before converting to CMYK, make sure you save an RGB file for backup.
