Use the Pure Black Text/Graphics option only when printing composites, not
when printing separations.

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. These
elements are not affected by the Pure Black Text/Graphics option. For details, see
the application notes. 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 Level 3 driver for
Windows 2000/XP. To print this single-color black at the maximum toner density of
the copier, set the Pure Black Text/Graphics option to On.
Black Overprint
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.
•
On
—Black text overprints colored backgrounds, eliminating white gaps and
reducing halo effects or misregistration of colors. Setting Black Overprint to On
automatically activates the Pure Black Text/Graphics option.
•
Off
—Black text knocks out colored backgrounds.

RGB
Prints 100% black
With the default profile, prints a rich black using
all toners.
CMYK
Prints only with black toner, because CMYK
simulations preserve the black channel. The actual
amount of toner used depends on the current
simulation and the calibration state of the copier.
Spot
Prints only with black toner, because spot color
simulations preserve the black channel. The actual
amount of toner used depends on the current
simulation and the calibration state of the copier.
