Desktop versus ColorPASS color management

A desktop color management system uses ICC profiles to convert colors from one
device gamut to the next (see Appendix B). The color data is converted when it is
passed from one application to another or when the job is sent to the copier, so the
processing occurs on your computer as opposed to the ColorPASS.
One advantage of using ColorWise color management over desktop color management
is that your computer is spared the added processing chores; delaying color conversions
until the color data reaches the ColorPASS frees up your computer so you can
continue working, and color conversions on the ColorPASS are in most cases much
faster than similar conversions on a host computer.
Managing most or all of your color on the ColorPASS can also eliminate the potential
for undesirable color management-related conflicts, such as iterative color conversions
and inconsistent color. The ColorPASS applies global corrections to specific groups of
RGB, CMYK, and PANTONE colors to avoid such conflicts.
Finally, by sending RGB files instead of larger CMYK files from applications to the
ColorPASS, network traffic is minimized and jobs are generally printed more quickly.
ColorWise uses ICC profiles to convert colors to the copier gamut or to simulate other
devices such as an offset printing press. ColorWise manages color conversions for all
users printing to the ColorPASS from Windows and Mac OS computers. It lets users
follow a simple workflow with minimal intervention using robust default settings,
while giving advanced users the control and precision they need.
The ColorPASS can intelligently manage the printed appearance of RGB, CMYK, and
PANTONE colors. You can let the ColorPASS manage color for most short-run color
printing jobs without adjusting any settings.
