Color dropout
You can filter out a dark background from the image content, for example black text on green paper or red instructions on a form. Removing colors from the scan reduces the scan file size. You can select to filter out a color channel (red, green, or blue) or up to three specific colors. The sensitivity setting controls how closely a scanned color must approximate a specified color in order to be filtered out.
•A sensitivity of 1 creates the largest variable color drop out range. All colors that are similar to the specified colors are eliminated from the scan.
•A sensitivity of 10 creates the smallest variable color drop out range. Only those colors that very closely approximate the specified colors are eliminated from the scan.
To select colors to eliminate from a scan in an HP Smart Document Scan Software profile, follow these steps:
1.Open the HP Smart Document Scan Software.
