Black Text and Graphics
The Black Text and Graphics option affects black text and vector graphics. Under most
circumstances, set this option to Pure Black On. When Black Text and 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 dry ink only. The black text and line art do not
exhibit halftone artifacts (as long as the digital press is calibrated correctly) and are not
misregistered, since one dry ink is used. In addition, this setting eliminates blasting. This
option must be set to Pure Black On if you want to set the Black Overprint option to Text or
Te xt / Gr a ph i cs .
For some jobs, it is preferable to set this option to Normal, for example, if the page includes
gradient fills that use black. The following table describes the behavior of the Black Text and
Graphics option with black data defined in different color spaces.
