Workflow 3 bypassing ColorWise—not recommended
Bypassing ColorWise color management, while an option, is not a recommended
workflow. When you bypass ColorWise, you must choose colors using only CMYK
formulas designed specifically for your copier, and you must print with the CMYK
Simulation option set to Match Copy. The ColorPASS still prints pages using your
PostScript files, and drives the copier and its accessories, but it does not perform
CMYK color transformation, nor does it consider the calibration of the copier.
Calibration is needed in order to get consistent output, since the color response from
your copier varies significantly depending on wear, heat, humidity, and service.
The diagram below indicates that no modifications are made to colors in this
workflow.

Turn off color management in your application
Generally, when printing to the ColorPASS, it is best to disable color management in
the application to ensure that the ColorPASS receives color data properly and prints it
accurately.
Save your files using color-safe settings
There are several additional steps you can take to ensure color accuracy.
• When saving EPS files, do not include PostScript Color Management information.
This minimizes the risk conflicting data and multiple color conversions. PostScript
Color Management causes your CMYK and RGB colors to be interpreted by the
ColorPASS as though they were supplied in the Lab color space and, as a result, to
be processed by CRDs rather than your simulation settings.
