Adjusting the Contrast (Sharpness)
This mode enables you to scan original images with a sharper or softer contrast. To
scan text or lines sharply, use the [High] setting. To scan originals containing
printed photographs or other halftones, use the [Low] setting.
■ Low
If you want to scan an original containing halftones, such as a printed photograph, using
the Photo mode, the moiré effect (a shimmering, wavy pattern) may occur. However, you
can lessen the moiré effect by using the [Low] setting to produce a clearer image.
■ High
This setting enhances the edges of original images so that faint or fine text is scanned
with a sharper contrast. This setting is particularly suited for scanning blueprints and faint
pencil drawn images.
