Document Halftones (Xerox Features tab)
Halftone is the process by which images are printed as a pattern of
many small dots. The size and density of the dots produce shades
of light and dark in the image when it is printed. Also, different
combinations of the four primary toner colors produce an
extensive range of possible colors. You can choose from two
Halftone Settings—Quad Dot and Smooth Screen.
QUAD DOT
Quad Dot is a patented Xerox technology which produces clear,
well-defined pictures and graphics. It provides smoother fine lines
with less visible grain.
SMOOTH SCREEN
Smooth Screen halftones distribute the halftone dots in a more
random pattern in order to produce a smoother effect for color
sweeps.
