1-2 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.
N OTE : 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.
