Unsharp Mask - Canon imageCLASS MF5730 Software Manual

■ [Unsharp Mask]
Set to [ON] to emphasize and make sharper the outline of an image. This setting is
selected by default. It is effective for scanning photos etc., which have a soft focus.
IMPORTANT
You cannot set [Unsharp Mask] to [ON] if [Black and White] or [Text Enhanced] is
selected in [Color Mode].
■ [Descreen]
Set to [ON] when scanning printed photographs and pictures. The default setting is
[OFF].
IMPORTANT
•
You cannot set [Descreen] to [ON] if [Black and White] or [Text Enhanced] is selected in
[Color Mode].
•
Even if [Descreen] is set to [ON], some moire effect may remain if [Unsharp Mask] is also
set to [ON]. In this case, disable [Unsharp Mask].
•
[Descreen] cannot be set to [ON] when scanning from an application which will not
display the [ScanGear MF] dialog box. If you are scanning from the MF Toolbox without
using ScanGear MF, select [Color (Magazine)] in [Scan Mode] to activate [Descreen].
NOTE
•
Printed photographs and pictures are displayed as a collection of fine dots. If you scan
without descreen, the dots may interfere with each other and cause an unevenness of
gradation and a striped pattern in the image. [Descreen] is the function for reducing this
moire effect.
•
Selecting [Magazine (Color)] in [Select Document Type] in Simple Mode has the same
effect as selecting [Descreen] in Advanced Mode.
