3. Resolution
Shows resolutions that selected scanner supports. As a rule at least 300 DPI (dots per inch) is a recommended resolution for documents. Most OCR engines will be able to recognize correctly characters on documents with such resolution. Selecting higher resolution will lead to slower scanning although the quality will be better.

Usually: Black/White, Gray or Color.  If black and white images with better quality are required use “Image Enhancement” feature instead of scanning with Black/White color mode. To use it select Gray color mode and go to “Image enhancement” tab and check “Binarize” and “All images” options. Please see details about image enhancement features available in RemoteDesktopTwain in topic “Image Enhancement”.
