11-12 GA-1120 Color Management - Toshiba

1-12 GA-1120 Color Management
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 clear this option, for example, if the page includes
gradient fills that use black. The following table describes the behavior of the Pure
Black Text/Graphics option with black data defined in different color spaces.
NOTE: The Pure Black Text/Graphics option can be used only when printing
composites, not when printing separations.

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.
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 GA-1120.
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.
