data with ColorSync profiles. Some PostScript applications also provide independent
color management features that use ColorSync profiles.
To use the AdobePS driver to perform color management, choose the ColorSync Color
Matching setting and specify a ColorSync printer profile when you print (see
page 4-2). With these settings, the AdobePS driver performs color conversions and
sends the resulting color data to the DocuColor 40 CP. For information on color
management tools provided with applications, see the application notes.
Source color space profiles
You can specify a ColorSync source color profile for your Mac OS computer with the
ColorSync System Profile Control Panel (see Getting Started). The recommended
source color profile for printing to your DocuColor 40 CP print device is the EFIRGB
ICC profile included in your DocuColor 40 CP user software. The source color space
defined by this profile is the same as that defined by the EFIRGB setting of the RGB
Source option (see page 2-8).
The RGB Source setting overrides the ColorSync System Profile setting for RGB data
sent to the DocuColor 40 CP. If you do not want the ColorSync profile setting to be
overridden, set the RGB Source print option to Off.
The RGB Source setting does not override other source profile settings in cases where
you use the printer driver or your application's color management system to perform
color conversions. For example, if you print using the ColorSync Color Matching
setting (as described above), the printer driver performs the color conversion and sends
CMYK data to the DocuColor 40 CP. In another example, if you assign a ColorSync
source profile to an RGB image placed in a document, the application performs the
conversion to CMYK and the assigned source profile is not overridden by the RGB
Source setting. In these cases, where CMYK data is sent to the DocuColor 40 CP,
choose an appropriate CMYK Simulation setting for the print job.
Target profiles
The target profile, or printer profile, contains information about the color space and
gamut of the target print device. If you use the ColorSync Color Matching setting of
the AdobePS driver, you must specify the printer profile that ColorSync will use to
perform its color conversions.
