Adjusting the Tone of the Preview Image
The tone of an image is its shading and combination of colors. Adjusting
grayscale tones can enhance the contrast of a grayscale image. You can
produce a wide range of visual effects in your preview image by
adjusting the different settings on the Tone tab.
If you selected black and white or text enhanced as the scan mode, the
Tone tab is not available for selection. In these cases, you must adjust the
tone of the image with the contrast/brightness settings on the C5500 tab.
Exploring the Tone Tab
The Tone tab looks similar to this:
Tone Toolbar
Using the buttons on the Tone toolbar, you can access settings which
affect different aspects of image tone, and give you great flexibility in
manipulating your image tone before scanning the image.
