Pure Black Text/Graphics
The Pure Black Text/Graphics option affects the printout for black text and
vector

on a page. Under most circumstances, leave this option set to On. When
Pure Black Text/Graphics is on, black colors generated by applications (for example,
RGB = 0, 0, 0; CMYK = 0%, 0%, 0%, 100%; or K = 100%) are printed using the
maximum amount of black toner allowed by the calibration curve. This means the

artifacts
(as long as the copier/printer is
calibrated correctly) and will not be misregistered, since there is only one toner used.

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 Fiery X3e.
These elements are not affected by the Pure Black Text/Graphics option. For details,
see the application notes. 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
copier/printer, set the Pure Black Text/Graphics option to On.

One example of how you might use this setting is with a page that contains black text
on a light blue background. The background blue color is CMYK = 40%, 30%, 0%,
0% and the black text is CMYK = 0%, 0%, 0%, 100%.

0% and the black text is CMYK = 0%, 0%, 0%, 100%.
• With Black Overprint set to Text or Text & Graphics, the final text or text/graphic
portions of the page are overprinted, or combined with the underlying colors. Black
colors generated by applications (for example, RGB = 0%, 0%, 0%; CMYK = 0%,
0%, 0%, 100%) are printed using the maximum amount of black toner allowed by
the calibration curve. This means that black text and line art will not exhibit
halftone artifacts (as long as the copier/printer is calibrated correctly). There is no
transition in the cyan and magenta toners, and the quality of the output is improved
since it will not show artifacts near the edges of the text or text/graphics. The option
also works with text defined in the RGB color space, that is RGB = 0, 0, 0.
