Adjusting the Contrast (Sharpness)

This mode enables you to scan and record the originals with a sharper or softer contrast. To reproduce text or lines with a sharper contrast, use [High] as the setting. To scan originals containing printed photographs or other halftones with a softer contrast, use [Low] as the setting.

  • Low

If you 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 this moiré effect by using [Low] as the setting to produce a clearer image.

  • High

This setting enhances the edges of original images so that faint or fine text is reproduced with a sharper contrast. This setting is particularly suited to scanning blueprints and faint pencil drawn images.
