Filter out a color from a document (color channel dropout)
With HP Scanjet 1000, you can filter out a color channel (red, green, or blue).
Removing colors from the scan might reduce the scan file size and improve optical
character recognition (OCR) results.
To select colors to eliminate from a scan in the HP Scanjet 1000 TWAIN user interface,
follows these steps:
1. Start the scanning software, and then select the TWAIN data source.
2. On the TWAIN user interface, press the Color Dropout tab, choose the color
channel you wish to remove from the Color drop-down list.
For information about the color dropout settings, see the online help for the scanning
software that you are using.
NOTE: The color channel filter only applies to grayscale scans and to
black and white scans.
