Excluding A Color In The Image(Dropout Color) - Fujitsu fi-4120C Operator's Manual

4.3 Excluding a Color in the
Image(dropout color)
A selected color information (primary colors: red, green or blue)
can be excluded (dropped out) from the images when they are
scanned.
For example, if the document contains black text enclosed by a
green frame, you can set the scanner to scan only black areas in
the document (i.e. the color green is "dropped out").
To set the scanner to scan documents with a selected color
dropped out, change the settings in the [TWAIN Driver] dialog box.
The following shows the procedure for changing the settings in this
dialog box.
