Color Dropout tab
Electronic Color Dropout is used to eliminate a form’s background so that a
document management system may automatically (through OCR and ICR
technology) read pertinent data without interference from the lines and boxes
of the form. The i50/i60/i80 Scanners can drop out either red, green, or blue.
The Color Dropout tab allows you to select the desired dropout color.
Color Dropout is only available for bitonal and grayscale image setups.
Color dropout
—select the color to be removed. Select None if you do not
want any color to be removed.
For example, if your image contains red text or a red background, choose
Remove red
to remove the red text or red background.
Tip:
Adjusting the Threshold and Contrast settings may be required to improve
color dropout and, therefore, overall image quality (i.e., to completely remove
the background color).
