General Processing Options
When scanning and opening documents, Readiris applies several general processing options.
To access these options:
 On the Readiris menu, click Preferences.
 The Preferences window opens on the General tab.
The options you set here are applied as default to all the documents you'll open or scan.
Preprocessing Options.
Smoothen color and grayscale images
This option is activated by default. It renders grayscale and color images more homogeneous by
smoothening out differences in intensity. As a result, a stronger contrast is created between the
foreground (text) and background (artwork). Sometimes smoothening is the only way to separate
text from a colored background.
Process as 300 dpi
Select the option Process as 300 dpi when you are processing images of an incorrect or unknown
resolution. The images will be processed as if they had a 300 dpi resolution.
