This menu allows you to select a PostScript emulation level.
This option enables or disables gamma correction for PostScript files.
For more information, see chapter 5, “Additional Technical Informa-
tion,” in the
Reference
.
Menu Administration/Emulations/PostScript/Emulation Level
Choices Level 2—For PostScript Level 2 files and most Level 1 files.
Level 1 B/W—For files that contain only black-and-white
PostScript Level 1 operators. This mode does not support
the PostScript color operators; the use of color operators
could cause the print job to fail.
Level 1 Color—For files that contain color PostScript Level 1
operators. This mode accepts color PostScript Level 1
operators and translates these commands to the
appropriate grayscale. This is the recommended setting for
Level 1 compatibility since it contains all of the commands
in Level 1 B/W and the color commands.
Default Level 2
Notes In general, we recommend that you use the Level 2 option.
Use the Level 1 B/W and Level 1 Color options only if you have
files prepared in an application which is not fully compatible
with Adobe’s PostScript Level 2 page description language.
Menu Administration/Emulations/PostScript/Gamma Correction
Choices No—Disables gamma correction
Yes—Enables gamma correction, which adjusts the range of
gray levels to give you the best possible image. Gamma
correction sharpens overall mid-range contrast while blacks
(shadows) and white (highlights) keep their original values.
You can use this option to correct gray-scale problems or to
accenturate detail for scanned images.
