Filter
—The 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. The Filter
option applies to Black&White or Greyscale Mode.
•
Reduce Moire Patterns
—Moire patterns are wavy, rippled
lines that sometimes appear on the scanned images of
photographs or illustrations, particularly newspaper and
magazine illustrations. Selecting
Reduce Moire Patterns
will limit or eliminate moire patterns in the scanned image.
This option is only available for the Greyscale or Color
Mode at 200 dpi or less.
