1-10 iR C2100/2100S Color Management
NOTE: The Pure Black Text/Graphics option can be used 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 iR C2100/2100S. These elements are not affected by the Pure Black Text/
Graphics option. See the application notes for details. 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. To print this
single-color black at the maximum toner density of the copier/printer, set the
Pure Black Text/Graphics option to On.
Black Overprint
The Black Overprint option lets you 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/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 copier/printer.
