Black Overprint

This setting allows you to choose a specific way to print black text when printing
black text over a color background or graphics.
If [On] is selected, you can overprint black text. When this setting is used in
combination with 'Pure Black Text', 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. Overprinting also reduces misalignment of colors and a halo
effect that can appear around the edge of the text.
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. This may result in the black text appearing lighter, or
cause a halo effect that can appear around the edge of the text.
NOTE
This setting is only applied, and has an effect on, pure black if 'Pure Black Text' is
set to [On].
Brightness
85 to 115%; 100% *

between 85% and 115% in increments of 5%.
Selecting [85%] makes the image brighter, and selecting [115%] makes it darker.
