If you use gamma corrections in combination with XANTÉ’s new
enhanced screening technology, you can further fine tune your
output quality. See “Levels of Gray” earlier in this chapter and the
next section, “Enhanced Screening,” for more details.
Enhanced Screening
XANTÉ’s enhanced screening allows you to select from the normal
(default) or the enhanced screens defined by 145, 197, or 256 levels
of gray using either the printer’s front panel or via software printer
setup. If you use the front panel, the default enhanced screen is setup
under the MISC:SCREEN menus. If you use the software printer
setup, you can select the levels of gray and gamma settings
simultaneously. Gray level and line screen combinations of enhanced
screens are defined as:
Levels Line Screens
of Gray 600 dpi 1200 dpi
145 70 140
197 60 120
256 53 106
There are nineteen possible gamma correction and levels of gray
combinations from which you can choose to fine tune your output
quality. Depending on your printing environment, Macintosh or PC,
use one of the following procedures to select the enhanced screens.
In a Macintosh environment, use the following procedure to select
the enhanced screens.
1. Select Print… from the File menu from within your
application. The print dialog box appears.
