Halftones are screen patterns achieved by printing dots
or lines in a specific pattern. The distance between the
dots is fixed. Dot size varies in accordance to the strength
of the color. The darker the color the larger the dot.

Halftones supported on the iGen3 include 150 dot, 175
dot, 200 dot and stochastic screens. The DC 20xx/60xx
series supports 150 dot, 200 dot, 200 line, 300 line, and
600 line screens.

Stochastic halftones randomly apply screens when the
difference in tone varies by different concentrations of
dots and by dot sizes.

Image Resample
Interpolation is a method to achieve maximum image
quality. Interpolation estimates a value of function
between two known values and attempts to produce a
smooth transition between adjacent samples rather than
replicating pixels which would result in “blocky” images.
The supported interpolation methods include:
