Advanced Mode - [Halftone] tab 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. NOTE • The brightness of color and grayscale images are expressed as a value between 0 and 255 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 Move the [Threshold] slider to the right to increase the threshold value and thus reduce the white areas (black areas will increase). Move 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). 104

Advanced Mode - [Halftone] tab
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.
NOTE
• The brightness of color and grayscale images are expressed as a value between 0 and 255 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
Move the [Threshold] slider to the right to increase the threshold value and thus reduce
the white areas (black areas will increase). Move 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).
