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 ColorPASS.
These elements are not affected by the Pure Black Text/Graphics option. See the
application notes for details. 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. To print this single-color black at the maximum toner density of the
copier, set the Pure Black Text/Graphics option to On.
