1-10 ColorPASS Color Management
You can also use ColorWise Pro Tools' Profile Manager to download your own output
profile to the ColorPASS (see page 4-5). 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 for Windows 95/98/Me and have Two-
Way Communication enabled, 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 or Windows NT computer, or the Microsoft
PostScript driver from a Windows 2000 computer, downloaded or custom profiles
appear as Output-1 through Output-10. For more information on Two-Way
Communication, see Getting Started.

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
the On position. 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 turn this option Off, for example, if the page includes
gradient fills that use black. The table below describes the behavior of the Pure Black
Text/Graphics option with black data defined in different color spaces.
