Edge Smoothing
Edge Smoothing is a technique used for improving the print quality of text and
graphics. Indentations in curved lines are automatically smoothed to produce a
clearer appearance.
Limitation
Printing photographs or images containing gradations may result in a change
in image quality with Edge Smoothing on.
