• Invert image—only available for Black&White Mode, this option reverses the black and whites of an image.
• Color dropout—color dropout is the ability of your scanner to automatically remove a color from a scanned
image. For example, if you are scanning a letter with a red watermark, you can choose to filter out the red so
the scanned letter just shows the text and not the red watermark. Color dropout applies to Black & White or
Grayscale scanning modes.
Advanced Settings Tab
Use the Advanced Settings tab to set color correction options for Color or Grayscale scanning. Drag the sliders to the
left and right to change the color settings. As you do, the image changes to show the effects of the new settings.
• Color saturation—the strength or purity of a color. This option is only available when the selected scan mode
is Color.
• Color hue—the color your eyes see as reflected from the image. This option is only available when the
selected scan mode is Color.
