If [Black and white] is selected in [Color Mode], the [Color] tab will become the [Halftone] tab. On the
[Halftone] tab, you can set threshold.
You can set up the [Halftone] tab without having to display a preview and the settings will be active when
you scan.
The brightness of color and grayscale images is expressed as a value between 0 and 225 but brightness
of black and white images is expressed in terms of either black or white including the parts of an image
which are a color between the two. The boundary at which black and white is divided is called Threshold.
By adjusting the threshold, you can sharpen characters in a text document and reduce back-printing
such as in newspapers.
In ScanGear MP Advanced Mode, follow the step below.
1 Drag the slider to the right to increase the threshold value and thus reduce the white areas (black
areas will increase). Drag the slider to the left to decrease the threshold value and thus increase the
white areas (black areas will reduce). You can also enter a value (0 to 255).
