About working spaces


    Among other options, predefined color management settings specify the default color profiles to be associated with the RGB and CMYK color models. Central to the color management workflow, these default profiles are known as the RGB and CMYK working spaces, respectively. The working spaces specified by predefined settings represent the color profiles that will produce the best color fidelity for several common output conditions. For example, the U.S. Prepress Defaults setting uses a CMYK working space that is designed to preserve color consistency under standard Specifications for Web Offset Publications (SWOP) press conditions.

    A working space acts as the default color profile for newly created documents that use the associated color model. For example, if Adobe RGB (1998) is the current RGB working space, each new RGB document that you create will use colors within the Adobe RGB (1998) gamut. Working spaces also define the destination gamut of documents converted to the RGB or CMYK color model.
