Color Dropout  
Top  Previous  Next

 
Color Dropout allows you to remove a color channel (Red, Green or Blue) while scanning.  
 
For example, if your original document contains blue texts or a blue stamp (e.g., a bill or invoice) and you want to discard it from your image, you may select Blue Channel from the drop-down list.
