SCANNING FROM WINDOWS 98, ME, 2000, OR XP 43

COLOR DROP-OUT

Color drop-out is the ability of your scanner to automatically remove

one color from a scanned item. For example, if you are scanning a letter

with a red watermark, you can choose to drop-out the color red (the R

Channel) so the scanned letter just shows the text and not the red

watermark.

Color drop-out applies when you select the scanning image types of

Black and White, Halftone, 8-Bit Gray or 16-Bit Grayscale. It does not

apply to the image types of 24-Bit Color or 48-Bit Color.

Here are some examples of color drop-out:

The original with black

text on a blue background

The scanned item with the

B Channel (Blue) dropped out

The original with a red

watermark over black text

The scanned item with the

R Channel (Red) dropped out
