Cmyk Simulation And Calibration - Xerox DocuColor 40 Reference Manual

6-2 Page Layout Applications
All RGB images placed in your document are affected by the RGB Source and
Rendering Style settings. The DocuColor 40 CP color management system applies the
specified RGB Source setting to all RGB data and then uses the specified Rendering
Style (CRD) to perform a color conversion. An exception to this occurs if you assign
ICC profiles to RGB images using the application's color management tools (see "Tips
for advanced users"). In this case, the application performs the color conversion of the
image and sends CMYK data to the DocuColor 40 CP.
To take advantage of RGB Source and Rendering Style settings for images

imported into QuarkXPress 4.02, save the images in the EPS format.
Tips for advanced users
If you place multiple RGB images, some non-photographic and some photographic, a
single CRD may not be suitable for all the images. In this case you may want the
photographic images to bypass the CRD altogether. To accomplish this, separate the
image to CMYK data with a pixel-editing application such as Photoshop and perform
color correction on it. Then save it as an EPS or TIFF file and import it into the
document.
Alternatively, you can save the RGB image in TIFF format and assign it an ICC profile
and rendering intent when you import it into the document, if your application
supports this feature.

CMYK simulation and calibration

You can specify a press simulation target for the job with print option (see page 2-10).
The CMYK Simulation setting affects all CMYK color data sent by the page layout
application.
• If the document contains CMYK images that were separated for an offset press
standard, apply the corresponding CMYK Simulation setting. For example, for
images separated for SWOP, choose SWOP-Coated as the CMYK Simulation
setting.
• If the document contains CMYK images that were separated for a custom separation
(not a press standard), choose None as the CMYK Simulation setting or choose the
corresponding custom simulation target.
