1-11 Managing color on the Fiery
You can use the ColorWise Pro Tools Profile Manager to download your own output
profile to the Fiery (see page 3-4). Downloaded output profiles are at first associated
with the calibration target that is tied to the default output profile. As mentioned
above, you can edit calibration target D-Max values separately.
If you are printing with the PostScript driver from a Windows computer and have
enabled two-way communication, the name of each downloaded or custom profile is
represented in the Output Profile setting pop-up menu. If you are printing with the
AdobePS driver from a Mac OS computer, downloaded or custom profiles appear as
Output-1 through Output-10. For more information on two-way communication, see
the User Software Installation Guide.

Pure Black Text/Graphics

The Pure Black Text/Graphics option affects the printout for black text and vector
graphics on a page. Under most circumstances, it is preferable to 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 artifacts and will not be misregistered, since there is only one
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.
