HP Scanjet Enterprise 7000 s2 - Filter out color from a document (color dropout)

Filter out color from a document (color dropout)
You can filter out a color channel (red, green, or blue) or up to three individual colors. For specific
colors, the sensitivity setting controls how closely a scanned color must approximate the specified
color.
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 an HP Smart Document Scan Software profile, follow
these steps:
1. Open the HP Smart Document Scan Software.
2. Select a scan profile, and then click Edit profile.
3. On the Scan Settings tab of the Profile Settings dialog box, click Color Dropout.
4. Under Color dropout, specify the color dropout settings.
Only the color dropout options available for your scanner are selectable.
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.
Specific color filters apply to all color modes.
Use the ISIS or TWAIN user interface to filter out color when scanning from non-HP scanning
software.
