Black overprint eliminates the white edge between the printed 

fonts and the colored background.
Black overprint can only be used when printing 100 percent 

black text over a background color.

1. Black Overprint may not be available with some software 

applications.

2. The fonts (characters) must be 100 per cent black. If 

they are not, they are treated as graphics. Black 

overprint will not work.
Example:
If you print large letters on a color background using 

• a Microsoft Office software application 
• a True Type font 
• Windows XP, Server 2003, or 2000

Black Overprint won’t work.
Replace the True Type font with a printer font.

3. When the background color is very dark, the toner may 

not fuse correctly.
Change the background color to a lighter color.

4. Black Overprint can only be used in Mac OS 10.2 and 

10.3 if you are using an application that specifies RGB 

color space and you are using PostScript Color Matching.
