Setting Color Dropout
values Electronic Color Dropout is used to eliminate a form’s background so
that a document management system may automatically (through OCR
and ICR technology) read pertinent data without interference from the
lines and boxes of the form. The Color Dropout dialog box allows you to
select the desired dropout color, and alter the filter threshold and
background.
Electronic color dropout is available only for binary images.
When Color Dropout is selected from the More Scanner Settings dialog
box, the Color Dropout dialog box is displayed:
Side  select the side you want to apply Color Dropout values to 
either Front or Back.
Dropout Color  the i800 Series Scanners can drop out red, green or
blue. None is the default.
