PostScript applications, such as QuarkXPress, may convert elements defined as 

RGB=0, 0, 0 to four-color CMYK black before sending the job to the Fiery EXP6000/
EXP5000. These elements are not affected by the Pure Black Text/Graphics option. For more 
information, see 

. Also, black text and line art defined as RGB=0, 0, 0 in 

office applications, such as Microsoft Word, are converted to single-color black (CMYK=0%, 
0%, 0%, 100%) by the Microsoft PostScript 3 printer driver for Windows 2000/XP/Server 
2003. To print this single-color black at the maximum toner density of the digital press, set 
Pure Black Text/Graphics to On.

The Rendering Style option specifies a CRD for color conversions. To control the appearance 
of images, such as prints from office applications or RGB photographs from Photoshop, select 
the appropriate rendering style. The Fiery EXP6000/EXP5000 allows you to choose from the 
four rendering styles currently found in industry standard ICC profiles.

: 

Typically results 

in less saturated output than 
presentation rendering when 
printing out-of-gamut colors. 
This style preserves tonal 
relationships in images.

Photographs, including scans and 
images from stock photography 
CDs and digital camera images.

Image, Contrast, 
and Perceptual

: 

Creates saturated 

colors but does not match printed 
colors precisely to displayed colors. 
In-gamut colors, such as flesh 
tones, are rendered well. 
This style is similar to the 
Photographic rendering style.

Artwork and graphs in 
presentations. In many cases, this 
style can be used for mixed pages 
that contain presentation graphics 
and photographs.

Saturation, 
Graphics

: 

Provides 

white-point transformation between 
the source and destination white 
points. For example, the bluish 
white color (gray) of a monitor is 
replaced by paper white. This style 
avoids visible borders between 
blank spaces and white objects. 

Advanced use when color matching 
is important, but you prefer white 
colors in the document to print 
as paper white. This style may 
also be used with PostScript color 
management to affect CMYK 
data for simulation purposes.

: 

Provides 

no white point transformation 
between the source and destination 
white points. For example, the bluish 
white color (gray) is not replaced 
by paper white.

Situations when exact colors are 
needed and visible borders are not 
distracting. This style may also be 
used with PostScript color 
management to affect CMYK 
data for simulation purposes.
