During scanning, one of the most important settings affecting
successful character recognition is scanner brightness. As
Figure 6–2 illustrates, the original documents you scan may vary
considerably.

Darkness of text, the lightness of the background, and the
amount of noise (dirt, smeared ink, fingerprints, handwriting,
and other marks) can all affect character recognition accuracy.
From the Preferences Panel (Figure 6–3) in the main window, you
can adjust brightness to compensate for the print quality and
background of a particular document.
