You can import images into documents created in illustration applications (such as Illustrator) 
and page layout applications (such as QuarkXPress). The recommended formats for images 
imported into page layout documents are 

. If you encounter a 

problem using a TIFF format image, use the EPS file format. Support for importing other file 
formats may be provided by individual applications. 

All RGB images placed in a document are affected by the RGB Source and Rendering Style 
settings. The ColorWise color management system applies the specified RGB Source setting 
to all RGB data and then uses the specified Rendering Style (

) to perform a color 

conversion. An exception to this occurs if you assign 

 to RGB images using the 

application’s color management tools (see the following section). In this case, the application 
performs the color conversion of the image and sends CMYK data to the Color Server.

To take advantage of RGB Source and Rendering Style settings for images imported 

into QuarkXPress, save images in the EPS format or use the Quark PrintRGB XTension, 
which outputs RGB TIFF image files without converting them to CMYK.

If you place multiple RGB images, mixed non-photographic and photographic, into a file, 
a single CRD may not optimize output for all the images. In this case, you can have 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 file as EPS or TIFF format and import it into the document. 

If your application supports this feature, you can save the RGB image in TIFF format and 
assign it an 

 when you import it into the document.

You can specify a CMYK Simulation profile and a CMYK simulation method for a job 
using the CMYK Simulation Profile and CMYK Simulation Method print options (see

). The CMYK Simulation setting affects all CMYK color data sent by the page layout 

or illustration application. It can also affect RGB data sent to a page layout application if RGB 
Separation is set to Simulation.

• If the document contains CMYK graphics that were separated for an offset press standard, 

apply the corresponding CMYK Simulation setting. For example, for graphics separated 
for 

, choose SWOP as the CMYK Simulation setting. 

If you print separations to the Color Server and choose to use the Combine Separations 
feature in conjunction with Full Simulation, the result may not match that of the same 
page printed as composite.

• If the document contains CMYK graphics that were separated according to the color 

 (not a press standard profile), specify the 

corresponding profile as the CMYK Simulation Profile setting on the Color Server. 

For more information on downloading CMYK Simulation profiles to the Color Server with 
ColorWise Pro Tools, see 

.

If your site has installed the Fiery Graphic Arts Package (not available for all Color Server 
models), you can define halftone screens from several PostScript applications and use them 
when printing. The results vary depending on the application.

To define a halftone screen, use the application to adjust the Frequency and Angle values of 
the halftone screen. For applications that use the Color Server default (InDesign, FreeHand, 
QuarkXPress, and Illustrator 10), the ink dots are round. For applications that define 
their own shape and do not use the Color Server default (PageMaker, Photoshop, and 
Illustrator 9),the halftone dots may be a different shape. When you print the job, choose 
Application Defined for the Halftone Screen print option.

The Frequency and Angle settings in the Application Defined halftone screen are used 
regardless of whether the setting for Combine Separations is set to On or Off. For special 
instructions for printing separations with Photoshop, see 

In general, using halftone screens is not recommended because the print output will 

have visible dots of toner rather than smooth blends. Use halftone screens only when 
necessary to achieve a specific style of print output.

To ensure color accuracy, take the following steps:

• When saving EPS files, do not include PostScript Color Management information. This 

minimizes the risk of conflicting data and multiple color conversions. PostScript Color 
Management causes your CMYK and RGB colors to be interpreted by the Color Server as 
though they were supplied in the Lab color space and, as a result, processed by CRDs, 
rather than your simulation settings.

• Include ICC color information in files. ColorWise does not conflict with this information, 

and such data is useful for identifying the specific color space used by your files.

• Do not include halftone and transfer functions.

• Turn off color management in the printer driver. 

On Windows computers, if the printer driver offers Image Color Matching options, select 
Printer Image Color Matching.

On Mac OS computers, set the printer driver to include no color management commands 
at print time (see
