Uneven-Toned Background
Most suitable for documents with non-uniform
background typically due to cut-and-pasted
pieces being attached.
Selecting [Uneven-Toned Background] under
[Others...] displays the [Uneven-Toned Back-
ground] screen, where you can calibrate the
size of unevenness in 80 levels.
Important •
Use [Uneven-Toned Background] for text/line
documents, and not for printed materials such as posters.
•
Make sure to check the finished result because the effect varies depending on the settings
of the size of unevenness.
