I Black Overprint
On * , Off
When printing black text in combination with a color background or graphics, the
text can be printed as part of the color background, or separately. This setting
allows you to choose a specific way to print black text for such a job.
If [On] is selected, you can overprint black text. When this setting is used in
combination with the Pure Black Text option, the machine first prints the full color
background, then lays the black text on the top of the color background as 100% K
(black) toner. The result is a darker and glossier appearance for the black text.
Overprinting also minimizes the misalignment of colors and the halo effect that
can appear around the edge of objects in the printed image.

Black Overprint 'On'
If [Off] is selected, black text is printed with knockouts. The machine first prints the
color background with the black text areas "knocked out" (no color is printed in the
text areas). The black text is then printed in the knocked out area, filling in the
areas not printed in color. The result is a flatter appearance for the black text.
