• Use Settings Below
Choose this option if you would like to adjust the
halftone screen settings within the printer driver. This
makes it possible to adjust the screen frequency and
angle settings.
Do not change these settings unless you have experience using
halftones and are familiar with the requirements of your
application and printer.
• Screen Frequency / Angle
These settings specify the values for the number of
lines per inch (frequency) and angle of the pattern that
you want to use for halftone screens. If you are getting
a moire pattern when you print graphics such as
photographs or detailed images, you might want to
adjust these settings. However, the default printer
settings should work in most cases.
Some applications might be incompatible with the
Halftoning feature and might ignore any values you
specify. Also, the DocuPrint NC60 might use
halftoning procedures that do not use the frequency
and angle values you specify.
