11 Adobe PSPrinter 8.5/8.6 - a Workaround for OfÞ ce

Applications on Macintosh

The Adobe PSPrinter 8.5/8.6 allows an output ICC proÞ le to be selected from the

print options dialogue. This section explains how you can utilise this option for

optimising your color output - especially for ofÞ ce applications, as mentioned above,

and other applications working with monitor RGB colors.

Using the ColorSync system proÞ le as a source proÞ le

The PSPrinter 8.5/8.6 color management feature is made for printing monitor RGB

color data. Therefore, this function always uses the ColorSync System ProÞ le as a

source proÞ le. The ColorSync System ProÞ le can be selected from the Control Panel.

To get the best result, RGB data from scanners should be converted to monitor

RGB before importing it into an OfÞ ce application. This conversion can be done, for

example, with the ColorSync Filter module for Photoshop, as described above.

• Select the output proÞ le in the driver.

The PSPrinter 8.5/8.6 Print Options dialogue offers two color management settings:

ColorSync Color Matching: This function performs a ColorSync based transformation

from RGB data to CMYK data using the ColorSync System ProÞ le for input and the

selected printer ICC proÞ le for output.

Postscript Color Matching: This function performs a Postscript-based transformation

from RGB data to CMYK data. It combines the ColorSync System ProÞ le for

input and the selected printer ICC proÞ le to a Color Rendering Dictionary (CRD).

A CRD is a Postscript Þ le deÞ ning the color conversion in the Postscript interpreter.

The CRD is downloaded to the controller together with the print job, the Postscript

interpreter uses this CRD for converting RGB to CMYK for this particular print job.

Note: If Printer’s Default is selected as Printer ProÞ le, the controller’s resident

CRDs are used. Select a Rendering Style to specify the CRD you need. The

default CRD is photographic and should be used with images. This can be a

useful setting for ofÞ ce applications.
