Pure Black Text/Graphics

The Pure Black Text/Graphics option affects the printout for black text and
graphics on a page. Under most circumstances, leave this option set to On. 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
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.
Use the Pure Black Text/Graphics option only when printing composites, not
