Print Gray as Black
When Print Gray as Black is enabled, any gray (any color where R=G=B or C=Y=M, or any
K-only color) in a job is printed using only black toner instead of processed black.

Rendering Styles
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 X3eTY2 allows you to choose from the four
rendering styles currently found in industry standard ICC profiles.

RGB Separation
The RGB Separation option determines how RGB colors (as well as Lab and XYZ colors) are
converted to CMYK. The name of this option is meant to be descriptive, since the option
defines the color spaces that are used by the Fiery X3eTY2 to “separate” the RGB data into
CMYK values.

The two choices available for this option determine whether RGB data is converted into the
full gamut of the MFP (

RGB data. For example, if a high-quality ICC profile is available for another print device, the
MFP can simulate the behavior of that device.

RGB Separation is also useful for prepress applications. For example, it allows you to
experiment with the appearance of an RGB scan under different press printing conditions,
without having to convert the RGB data to CMYK data for each condition. When the desired
printing condition is found, convert the file to CMYK, using the same CMYK simulation
profile you used during the experimentation.

RGB Source Profile
The RGB
source profile
setting allows you to define the characteristics of the RGB data in
your document so that the appropriate color conversion occurs on the Fiery X3eTY2.
Commonly used monitor color spaces are available from the printer driver and the
Fiery X3eTY2. For others, use ColorWise Pro Tools Profile Manager to download custom
monitor or scanner profiles.
