Descreen—select a setting from the drop-down list to specify the type
of document you are scanning in order to eliminate the moire pattern
(an undesirable pattern resulting from the incorrect screen angle of the
overprinting halftone) commonly found in printed material. You can
specify None, Newspaper, Magazine, or Catalog.
JPEG Quality—JPEG quality controls the amount of file compression
performed by Capture Software when producing JPEG images. Enter a value
between 10 and 255. A higher setting increases image compression (resulting
in smaller file sizes), but decreases image quality. A lower setting decreases
image compression (resulting in larger file sizes), but improves image quality.
The following settings can be used as guidelines.
Image Quality
Good
Better
Best
NOTE: If you are planning to batch output color or grayscale images
uncompressed using the "Uncompress images" batch output format,
use a JPEG Quality setting of 10 to minimize the amount of JPEG loss
when compressing and then decompressing color/grayscale images.
The Color tab is available only when the Color image type is selected.
Hue—specify a value in the Hue text box or click and drag the slider bar to
adjust the hue to a value from -180 to 180.

slider bar to adjust the color strength. Valid values are -100 to 100.
