● Scan mode – black and white.
Black and white scanning maximizes scanning speed but may result in the loss
of some character information. This may lower recognition in documents of
medium and low print quality.
● Scan mode – color.
Select this mode for documents that contain pictures, colored text or colored
backgrounds, so that you can retain the original colors. In all other cases, gray
scan mode is preferable.
● Brightness – a medium brightness value of around 50% should suffice for
most documents. Some documents scanned in black and white mode may
require additional brightness tuning.
Note: Scanning at 400 to 600 dpi resolution (instead of the default 300 dpi) or scanning in
grayscale or color (instead of black & white) mode takes more time. Some scanners
may take up to four times longer to scan at 600 dpi rather than 300 dpi resolution
scanning.
Set scanning parameters:
● To scan images using the ABBYY FineReader TWAIN interface, select the
Scanner Settings item in the Tools menu. The Scanner Settings dialog will
open. Select the appropriate scanning options from the dialog.
● If you wish to scan your images using the TWAINSource interface, your
scanner’s TWAIN dialog will open automatically when you click the 1Scan
button. Set the scanning parameters in the dialogue. Scanning options may
have different names depending on the scanner model. For example, for
brightness the word “threshold”, a “sun” symbol or a black and white circle
may be used. Consult your scanner documentation for a full description of
available options.
Tips on Brightness Tuning
To be recognized, a scanned image must be legible. Check the legibility of the image in the
Zoom window.
