4.4 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.
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.
