For example, if the radius is 3 and the number is 5, then the document is evaluated in sections of 3x3 pixels and if
there are more than 5 stray dots within a 3x3 area, they are not considered a speckle.
Filter
Use the Filter option to increase or decrease the sharpness in the scanned image. Click the drop down menu and
select an option from the list. Use the Mask slider to adjust the tolerance level of the filter.
Color Management
Select this option to use the scanner’s default Gamma table which has been calibrated to produce the best quality
results for your scanner. When this option is not selected, you may need to manually adjust the Gamma, Brightness
and Contrast settings. Please refer to the sections describing Gamma, Brightness and Contrast for more information
about the features and how to adjust the settings.
Moiré Reduction
Moiré patterns are wavy or rippled lines that may appear in the scanned images of newspapers and magazines, and
sometimes scanned images of photos, line drawings, and color scans of textured paper. Select the Moiré reduction
option to have the driver attempt to find and remove moiré patterns from the image. Please note that when Moiré
reduction is enabled the scanner may scan slower as the image is checked for moiré patterns. This option is only
available when scanning in Color or Gray.
Moiré radius—you can set the size of the area to be evaluated in the Moiré radius field. Adjusting the radius will
produce different results for the various types of items that can be scanned. With this feature, you may have to test
scan a few times, adjusting the Moiré radius as needed, until you obtain the best results for the type of paper in
your scan job. Note that the higher the number is in the Moiré radius field, the longer it will take the driver to
evaluate the image.
Color Dropout
Color dropout tells the scanner and software to remove a specific color from the image. You can choose either Red,
Green, or Blue, or define a custom color, to be dropped out of an image.
