Black Text/Graphics
The Black Text/Graphics option affects black text and
. Under most
circumstances, set this option to Pure Black On. When Black Text/Graphics is set to Pure
Black On, black colors generated by applications (for example, RGB=0, 0, 0 or CMYK=0%,
0%, 0%, 100%) are printed using black toner only. The black text and line art do not exhibit
halftone
(as long as the digital press is calibrated correctly) and are not misregistered,
since one toner is used. In addition, this setting eliminates
. This option must be set
to Pure Black On if you want to set the Black Overprint option to Text or Text/Graphics.
For some jobs, it is preferable to clear this option, for example, if the page includes
fills that use black. The following table describes the behavior of the Black Text/Graphics
option with black data defined in different color spaces.

OTE
:
Use the Black Text/Graphics option only when printing composites, not when printing
separations.
Color
Black Text/Graphics = Normal
Black Text/Graphics = Pure Black On or
Rich Black On
RGB=0,0,0
(all other RGB values are
unaffected by the Black Text/
Graphics setting)
RGB=0,0,0 is printed according to the definition
for RGB=0,0,0 in the output profile. This may
be a rich black using all toners if the output
profile specifies a rich black, or may be K-only
if the output profile specifies K-only for
RGB=0,0,0. The output is affected by the
calibration curve.
RGB=0,0,0 is printed as K-only, using the black
toner (Pure Black On) or 100% K plus 50%
Cyan (Rich Black On) using black and cyan
toners. All other RGB values are unaffected by
the Black Text/Graphics setting.
CMYK=0%,0%,0%,100%
(all other CMYK values are
unaffected by the Black Text/
Graphics setting)
CMYK=0%,0%,0%,100% may be printed as
K-only or as a rich black using all toners,
depending on the CMYK Simulation Profile
and CMYK Simulation Method settings.
For Quick and Full (Source GCR),
CMYK=0%,0%,0%,100% prints as K-only
and the amount of black toner is limited by
the simulation profile and the calibration curve.
For Full (Output GCR),
CMYK=0%,0%,0%,100% prints as K-only
and the amount of black toner is limited by
the simulation profile and the calibration curve.
Setting CMYK Simulation to ColorWise Off
disables the simulation profile and the
calibration curve. In this case, the black toner
is not limited by the calibration curve.
CMYK=0%,0%,0%,100% is printed as K-only,
using the black toner (Pure Black On) or 100%
K plus 50% Cyan (Rich Black On) using black
and cyan toners, regardless of the CMYK
Simulation Profile and CMYK Simulation
Method settings. All other CMYK values are
unaffected by the Black Text/Graphics setting.
Setting CMYK Simulation to ColorWise Off
disables the simulation profile and the
calibration curve. In this case, the black toner
is not limited by the calibration curve.
