GA-1121 Color Management

control the printing of these mixed-color documents with features that apply specifically to RGB, CMYK, or spot color data. GA-1121 color management generates CMYK data to be sent to the copier/printer.

The following diagram illustrates the print options in the GA-1121 color management process that affect color data conversions. You can access these print options when you send a print job to the GA-1121. Most of these options and settings are described in subsequent sections of this chapter.

RGB Source Profile is the only color option that applies strictly to RGB color data. The other options that affect RGB color also affect the more rarely used Lab, XYZ, and other calibrated color spaces.

NOTE: For users who are familiar with PostScript 3 color, RGB Source Profile affects all CIEBasedABC color spaces (if the source space is RGB). If you send CMYK data to the GA-1121 in CIEBasedDEFG format, for example, by choosing PostScript Color Management in Adobe Photoshop, the GA-1121 Rendering Style selection—which normally affects only RGB data—will also affect this CMYK data.
