• In the Scale box, type a new percentage.
• Click the up arrow to increase the percentage or click the down arrow

Setting Image Tones
The Tone tab contains settings that govern the image tone. “Tone” refers to
the shading and combination of colors in the image.
Adjusting colors and grayscale tones can enhance the richness of a color
image or the contrast of a grayscale image. You can produce a wide range of
visual effects for your preview image by adjusting the different settings on the
Tone tab.
Note: If you selected Black and White or Text Enhanced as the Scan
Mode on the Main tab, the Tone tab is not visible.
About the Tone Tab Settings
The Tone tab settings include five sub-settings that you select by clicking the
buttons on the Tone tab toolbar. These settings affect different aspects of
image tone, and give you great flexibility in manipulating your image tone
before scanning the image.
When you select one of the buttons on the Tone tab toolbar, the options
change.
