Importing Images - Xerox Fiery color server User Manual

6-2 Illustration Applications
If you define colors in RGB and print directly from the application, the
N :
OTE
application converts the RGB data to CMYK before sending it to the Color Server.
This conversion by the application will determine which ColorWise print options
affect your job. For example, if the application converts RGB black (defined in your
document as R0%, G0%, B0%) to four-color CMYK black when it sends the job to
the Color Server, the Pure Black Text/Graphics option in the PPD will have no effect
when you print the job.
You can also choose named colors from the PANTONE color library (see page 2-7).

Importing images

In general, all images placed in illustration applications should be in EPS file format.
All RGB images placed in a document are affected by the RGB Source and
Rendering Style settings in the PPD. The ColorWise 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 to CMYK.
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 the
following section). In this case, the application performs the color conversion
of the image and sends CMYK data to the Color Server.
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. Save the image as an EPS or TIFF file and import it into
the document. You can also save the RGB image in TIFF format and assign it an
ICC profile and rendering intent when you import it into the document (see the
discussions of specific applications in this chapter).
