Color Drop-out
This feature is available when Black and White, Halftone,
or 8-Bit Gray is selected on the Image Type drop-down menu.
Click on the Color Drop-out button to access a dialog box that
allows you to choose to remove the R (Red), G (Green), or B
(Blue) color channel while scanning.
For example, if your image contains red text or a red
background, choose R channel (red) to remove the red text or
red background.
This feature is applicable only for black-and-white and grayscale
images. Make sure that you have selected a black-and-white or
grayscale image type (on the Image Type drop-down menu)
when you use this option.
Tip
Increasing the brightness after removing one of the color
channels will make the image clearer.
