Lightness—specify a value in the Lightness box to adjust the color strength.

NOTE

These options are available only when the Color Adjustment button is enabled.

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-outbutton 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.

Increasing the brightness after removing one of the color channels will make the image clearer.

This function is particularly useful when you have to convert text using OCR software.
