The Halftone Sheet
The Halftone sheet is displayed only when Black and White has been se-
lected for the Color Mode on the Advanced Mode Main window. You can
set only Threshold in this sheet.
Threshold
Threshold determines whether portions of an original are scanned as black
or white. Drag the slider left to make the image lighter or drag it right to
make the image darker. Or you can also enter a value ( 0 - 255) directly into
the entry box to the right of the slider.
Setting the threshold value higher causes the black portions of the image to
increase. Setting it lower, causes the white portions to increase.
