Output Profile
The output profile is applied to all data in the print job, so make sure the
selected profile is right for your job. The default output profile consists of
both a profile for your copier/printer, describing its color characteristics, and
a calibration target that describes the expected behavior of the copier/printer.
You can use ColorWise Pro Tools' Profile Manager to download your own
output profile to the iR C2100/2100S (see page 4-5). Downloaded output
profiles are at first associated with the calibration target that is tied to the
default output profile.

Pure Black Text/Graphics

The Pure Black Text/Graphics option affects the printout for black text and
vector graphics on a page. Under most circumstances it is preferable to leave
this option set to the On position. When Pure Black Text/Graphics is on,
black colors generated by applications are printed using 100 percent black-
only toner (for example, RGB = 0, 0, 0; CMYK = 0%, 0%, 0%, 100%; or K
= 100%). This means the black text and line art will not exhibit halftone
artifacts and will not be misregistered, since there is only one toner used. In
addition, this setting eliminates blasting. This option is automatically set to
On when the Black Overprint option is set to On.
For some jobs it is preferable to turn this option Off, for example, if the page
includes gradient fills that use black. The table below describes the behavior
of the Pure Black Text/Graphics option with black data defined in different
color spaces.
