• More approximate—this option removes a wider range of colors based on the pure color selected
in the list or defined in the custom fields.
This option is only available when scanning in grayscale or black and white. The example below shows
the original text with a red watermark and the resulting image with the color removed.
Perform Color Correction
Apply color correction to the image so the displayed colors approximate the original item colors. Select
this option to use the scanner’s default Gamma table which has been calibrated to produce the best
quality color results for your scanner. When this option is not selected, the resulting scans will be dark
and the brightness, contrast, and gamma options will require a greater amount of adjustment to affect
the overall lightness of the image.
Advanced Panel Options
The options in this panel may also appear in the Main panel, but with additional settings for you to
fine-tune the feature you've selected. Select the Advanced source configuration mode to show this
panel.
Despeckle
This option removes speckles from the background. Speckles are small spots on an image that the
scanner interpreted as a valid part of the document. For example, an irregularity in the paper, a small
wrinkle, or holes where a staple was removed may show up as speckles in the scanned image. The
Despeckle option identifies these spots and removes them. This option is only available when scanning
in black and white.
Radius—this is the size of the area that is evaluated for stray dots.
