Xerox DocuColor 12 Printer with Fiery EX12 Dépliant

If you define colors in RGB and print directly from the application, the 

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 

).

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 

following section). In this case, the application performs the color conversion 
of the image and sends CMYK data to the Color Server.

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).
