Controls tab
The
Controls
tab of the
HP PrecisionScan Pro
Preferences
dialog box has option buttons for
selecting which control range readout to use for
scanning.
The control range sets the amount of tonal
resolution per color available for correction in the
Exposure Adjustment
and
Black & White Threshold
tools. Using a larger number of bits for the control
range results in greater control of compensation
for exposure or threshold correction.
