Scanning
• Color Filter—Color filter is the ability of your scanner to
automatically remove a color from a scanned item. For
example, if you are scanning a letter with a red watermark,
you can choose to filter out the red so the scanned letter
just shows the text and not the red watermark. Color filter
applies to Black&White or Grayscale Mode.
8. Click the Advanced Settings tab.
The options of the Advanced Settings tab are for the Color or
Grayscale scanning mode.
Saturation is the strength or purity of a color, hue is the color
your eyes see as reflected from the image, and gamma
controls the brightness of the midtones of the color.
9. Drag the sliders to the left and right to change the color
settings. As you do, the image changes to show the effects of
the new settings.
10. Click OK to save the new configuration.
It will now appear in the list of Scan Configurations on the One
Touch Properties window for the appropriate Destination
Applications.
