If you see the "Adjust brightness" warning message
ABBYY PDF Transformer+ will display a warning message during scanning if the brightness setting
is incorrect. You may also need to adjust the brightness setting when scanning in black–and–white
mode.
You can adjust the brightness setting in the scanning dialog box. The 50% setting works well in
most cases.
If the resulting image contains too many "sketchy" or "thick" letters, troubleshoot using the table
