Fine-Tuning Color Output
We’ve configured your printer so that most users don’t have to
change the default settings to get excellent color output, and we’ve
provided Q
COLOR
technology (through the QMS-supplied
Macintosh or Windows driver) to make it easy to automatically
optimize color output. (See “Q
COLOR
Automatic Color Control,”
earlier in this chapter, for more information.) However, the printer
is designed to allow you to change individual print-quality features
if you wish to, or if your application requires you to use a non-QMS
Macintosh or Windows driver.
This section gives more detailed information about the individual
color settings available:
■ Printer default halftone
■ Dither pattern (not available in the Macintosh driver)
■ Gamma correction
■ Color rendering dictionary (CRD)
These settings can be changed in the printer configuration menu or
in the QMS-supplied Macintosh or Windows driver. See chapter
3, “Connecting the Printer,” for information on installing these
drivers.
Printer Default Halftone Settings
Halftone settings, such as screen line frequency and screen angles,
play an important part in the appearance of a color print. For
example, incorrect halftone angles can cause prints to have a
mottled appearance, called moiré.
