Advanced Mode - [Settings] tab settings
You can adjust the following settings on the [Settings] tab.
[Filter processing]
z [Descreen]
Click [Descreen] when scanning printed photographs and pictures. This setting is not
selected by default.
IMPORTANT
You cannot select [Descreen] if [Black and White] or [Text Enhanced] is selected in [Color
Mode] on the [Main] tab, or if [Output Resolution] is greater than [600] dpi.
Even if [Descreen] is selected, some moire effect may remain if [Unsharp Mask] is also
selected. In this case, disable [Unsharp Mask].
[Descreen] cannot be set when scanning from an application which will not display the
ScanGear MP dialog box. If you are scanning from the MP Toolbox without using ScanGear
MP, 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] in [Type of original] in Simple Mode has the same effect as selecting
[Descreen] in [Filter processing] in Advanced Mode.
z [Unsharp mask]
Click 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.
