1-2 ColorPASS Color Management
ColorPASS color management generates CMYK data to be sent to the copier;
additional processing may then be performed before printing begins.
The diagram below illustrates the print options in the ColorPASS color management
process that affect color data conversions. You access these print options when you
send a print job to the ColorPASS. 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.

For users who are familiar with PostScript 3.0 color, RGB Source Profile affects
all CIEBasedABC color spaces (if the source space is RGB). If you send CMYK data to
the ColorPASS in CIEBasedDEFG format, for example, by choosing PostScript Color
Management in Adobe Photoshop, the ColorPASS’s Rendering Style selection—which
normally affects only RGB data—will also affect this CMYK data.
