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 EX7750. These
elements are not affected by the Pure Black Text/Graphics option. For details, see the
. 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 printer,
set the Pure Black Text/Graphics option to On.
