Black Overprint____________________
General Information
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.
Restrictions
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, 2000, or NT 4.0
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.x if you
are using an application that specifies RGB color space
and you are using PostScript Color Matching.
