Adjusting The Contrast (Sharpness) - Canon iR3245 Manual

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
sharpercontrast. This setting is particularly suited to scanning blueprints and faint pencil drawn
images.
Remark
For information on the modes which cannot be set in
combination with this mode, see "Combination of
Functions Chart(p.9-8)."
