Color Profiles in Photoshop

When you are working with images in Photoshop that are destined to be printed on a commercial printing press, they are typically in RGB color space and are converted for print to CMYK. Therefore, it is important that you define and assign a color profile to the RGB and CMYK color spaces that you will be working in and converting to in Photoshop. These are designated as the Working RGB and Working CMYK profiles in Photoshop’s Color Settings dialog box. The Working RGB profile you assign will control how RGB images are displayed and viewed through Photoshop. The Working CMYK profile will control both the CMYK values that appear in the Info palette while viewing an RGB image, and the CMYK values that result when you complete an RGB-to-CMYK conversion.
