Scanner settings affect how images are scanned. (These
settings can affect text recognition.) To change scanner
settings, choose
Scanner Settings
from the Settings
menu.
Image Type
Binary images include line art that are typically black
lines on a white background. Choose
Binary
for scanning
pages with text and line art.
Half-tones are graphics created using a grey-scale; that is,
true grey is used in the graphic (such as a photograph).
HP AccuPage-compatible scanners allow you to specify 16
or 256 levels of grey. Choose 16 levels for line art and 256
levels for photographs.
All other scanners allow you to choose
Dithered
for
scanning pages of half-tone images only. A dithered
pattern is an arrangement of black-and-white dots that
simulates a half-tone. Different dither patterns produce
different results, and it is generally much coarser than a
half-tone due to the limitation of scanning and printing at
300 dots-per-inch.
Because recognition requires a high contrast, sharp
definition, black-and-white image, WordScan will not let
you process text when
Dithered
is selected.
