[On]*, [Off]

This setting allows you to choose a specific way to print black text when printing black text over a color background or graphics.

If the document contains black text on a color background, "knocking out" (no color printed in the text areas) is not performed, which reduces the halo effect, a white border around the edge of the text.

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.
