black and white.
Scanning in black and white enables the system to scan at a higher
speed, but at the same time some character information is lost.
This may have an adverse effect on recognition quality in the case
of documents of medium-to-low print quality.
If you scan color documents that contain pictures, colored text, or
colored backgrounds, you may wish to retain the original colors in
your electronic document. Use the color scan mode in this
case. Otherwise use gray scan mode.
Brightness - - a medium brightness value of around 50%
should suffice for most cases.
Some documents scanned in black and white mode may require
additional brightness tuning.
Note: Scanning at 400-600 dpi resolution (instead of the
default 300 dpi) or scanning in grayscale or color (instead of
black & white) mode is more time consuming. In the case of
certain scanner models, 600 dpi resolution scanning can take up to
four times longer than 300 dpi resolution scanning.
