1-22 Fiery Color Management
ES3640e MFP Color Guide - 22
Note:
Use the Pure Black Text/Graphics option only when printing
composites, not when printing separations.
Note:
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
printer, set the Pure Black Text/Graphics option to On.
Black Overprint
The Black Overprint option allows you to specify whether or not
black text or text/graphics—defined as RGB = 0, 0, 0, or as CMYK
= 0%, 0%, 0%, 100%—overprints colored backgrounds.
•
Text
—Black text overprints colored backgrounds, eliminating
white gaps and reducing halo effects or misregistration of colors.

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 printer.
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 printer.
