Adjusting the Image Sharpness

You can adjust the sharpness to scan text and lines with a sharper contrast. You can also reduce the sharpness for the half-tone dots of printed photos, etc. to scan with a softer image.

Low

If you scan an original containing halftones, such as a printed image, the moiré effect (a shimmering, wavy pattern) may occur. In this case, you can lessen this moiré effect by using [Low] as the setting.
