Edge Enhancement
Edge Enhancement is an iGen3-specific feature that
outlines the non-saturated graphic objects and
produces a crisp edge. In previous releases of
DocuSP, Edge Enhancement was always applied and
could not be turned off. In DocuSP 4.2, the user can
choose to enable or disable this feature.
The Edge Enhancement selection can be set in the
Queue Manager, under Image Quality/Halftone, as
shown in the following image:

Edge Enhancement can also be selected in the Job
Manager and through the use of page exceptions. The
default state of the Edge Enhancement feature is
Enabled.
The ability to disable Edge Enhancement may be
advantageous to a customer who has an image with
blue fill on a single page of a multi-page PDF. If the
outline provided by Edge Enhancement does not
match the fill color, then Edge Enhancement may be
disabled on that specific page, as desired.
