The Color Dropout Tab
4.4.1
Color Dropout Selection
Color Dropout tab allows you to drop either of the red, blue, or
green color in your scanned image. If your image contains red
color watermark or background, choose the R (Red) channel
then any red watermark or background will be removed. This
feature is used to sharpen your text when using OCR (Optical
Character Recognition) software.
The “Custom” option allows you to specify your desired color to
be removed by entering its RGB (Red, Green, and Blue) value
respectively.
Tolerance: Specify the allowable color range to be removed for
the color you selected. Specified range: 1 ~ 100
The large the numeric value, the wider the color dropout range
is.
Note that this function supports only black & white and gray
images. Therefore, be sure to choose any black & white or
gray image type while applying this function.
