 color management system provides print options that affect the output of 

objects in various color spaces. By specifying the appropriate settings for each print option, 
you can obtain the expected results for your jobs.

This chapter provides an overview of the ColorWise management system that controls color 
on the Fiery X3eTY2 (see 

) and detailed explanations of each print option. For the 

location of each print option, see the following table. 

This chapter also provides information about 

 printer drivers and instructions for 

setting the ColorWise print options for Windows and Mac OS computers. For information 
about printer drivers, see 

.

Many of the color management features described in this chapter are available only 

with the PostScript driver, not with the PCL driver.

To modify Fiery X3eTY2 printing behavior, do any of the following:

• Specify ColorWise options for an individual print job using the menus that appear in the 

printer driver.

• Specify most ColorWise options as server defaults from Color Setup in ColorWise Pro 

Tools (see 

). You can also set default values from Fiery X3eTY2 Setup, as described 

. The defaults apply to all subsequent print jobs unless you 

override them.

• Specify ColorWise options, particularly default 

 settings and calibration 

options, from ColorWise Pro Tools. These options include default Simulation Profile (see 

), Simulation Method (see 

), default Source Profile (see 

), RGB 

Separation (see 

), and associated calibration set (see 

Applications allow you to generate color data for the Fiery X3eTY2 in many different 

. The most common type of color data produced from 

while prepress applications generally produce 

 data. Desktop applications also generate 

, such as PANTONE colors. To complicate matters, a single page may contain a 

mix of RGB, CMYK, and spot colors. The Fiery X3eTY2 allows you to control the printing 
of mixed-color documents with features that apply specifically to RGB, CMYK, or spot color 
data.

The following diagram illustrates the print options in the Fiery X3eTY2 color management 
process that affect color data conversions. You can access these print options when you send a 
print job to the Fiery X3eTY2. Most of these options and settings are described in subsequent 
sections of this chapter.

RGB 

 is the only color option that applies strictly to RGB color data. The other 

options that affect RGB color also affect the more rarely used Lab, XYZ, and other calibrated 
color spaces.

With PostScript 3 color, RGB Source Profile affects all CIEBasedABC color spaces 

(if the source space is RGB). For example, if you send CMYK data to the Fiery X3eTY2 in 
CIEBasedDEFG format by choosing PostScript Color Management in Photoshop, the setting 
for the Rendering Style print option, which normally affects only RGB data, also affects this 
CMYK data.

The following sections provide detailed explanations of the ColorWise print options and how 
these options affect print jobs.

Trapping is a technique where the size of objects is modified so that colors printed next to 
each other overlap slightly, in order to prevent white spaces between two colors. These white 
spaces, or “hollows,” can be caused by factors such as misregistration, the physical properties 
of the toners, and the stiffness of the media.

If you enable the Auto Trapping option, trapping is applied to the objects in a job.

The Black Detection option allows you to specify whether or not to detect black-and-white 
pages before printing your job. To use this option, set Color Mode to CMYK, Standard Color, 
or Expert Color.

•

 Select Off if your job consists of black-only text pages combined with a significant 

number of color pages.

•

 Select On if you are printing a predominantly black-and-white job. Black-and-white 

only pages will print with the proper billing information.

The Black Overprint option allows you to specify whether or not black text, defined as 
RGB=0, 0, 0, or as CMYK=0%, 0%, 0%, 100%, overprints colored backgrounds. 

•

 Black text overprints colored backgrounds, eliminating white gaps and reducing the 

halo effect or misregistration of colors. Choosing this setting automatically sets the Black 
Text/Graphics option to Pure Black On.

•

 Black text and graphics overprint colored backgrounds, eliminating 

white gaps and reducing halo effects or misregistration of colors. Choosing this setting 
automatically sets the Black Text/Graphics option to Pure Black On.

•

 Black text or text/graphics knocks out colored backgrounds.

Before sending the print job to the MFP, PostScript applications may perform their 

own black overprint conversions.

One example of how you might use this setting is a page that contains black text on a light 
blue background. The background blue is CMYK=40%, 30%, 0%, 0%. The black text is 
CMYK=0%, 0%, 0%, 100%.

• With Black Overprint set to Text or Text & Graphics, the final text or text/graphic 

portions of the page are overprinted, or combined with the underlying color. Black colors 
generated by applications (for example, RGB=0, 0, 0 or CMYK=0%, 0%, 0%, 100%) are 
printed using the black toner. This means that black text and line art does not exhibit 
halftone artifacts (as long as the MFP is calibrated correctly). No transition in cyan and 
magenta toners occurs. The quality of the output is improved, since it does not show 
artifacts near the edges of the text defined in the RGB color space (RGB=0, 0, 0).

• With Black Overprint Off, the border of the text or text/graphics is on an edge that has 

cyan and magenta toners on one side (outside the text) and black toner on the other side 
(inside the text). This transition may cause visible artifacts due to the practical limitations 
of the MFP.

Setting Black Overprint to Text/Graphics allows black text or graphics to overprint 

color backgrounds (see 

The reproduction of CMYK components is affected by the CMYK Simulation setting 

and calibration curve when CMYK is not 0%, 0%, 0%, 0%.

This feature is not available with the PCL driver.

The Black Text/Graphics option affects black text and 

. Under most 

circumstances, set this option to Pure Black On. When Black Text/Graphics is set to Pure 
Black On, black colors generated by applications (for example, RGB=0, 0, 0 or CMYK=0%, 
0%, 0%, 100%) are printed using black toner only. The black text and line art do not exhibit 
halftone 

 (as long as the MFP is calibrated correctly) and are not misregistered, since 

one toner is used. In addition, this setting eliminates 

. This option is automatically set 

to Pure Black On when the Black Overprint option is selected.

For some jobs, it is preferable to clear this option, for example, if the page includes 

fills that use black. The following table describes the behavior of the Black Text/Graphics 
option with black data defined in different color spaces.
