SCANNING WITH THE TWAIN INTERFACE 93
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 the Black&White and GreyScale Modes.
