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.
