&RQWUROVWDERSWLRQV
The Controls tab of the Preferences dialog box controls the control
range readout to use for scanning.
The control range sets the amount of tonal resolution per color
available for correction in the Adjust Exposure command and Adjust
Black & White Threshold command. Using a larger number of bits for
the control range results in greater control of compensation for
exposure or threshold correction.
Choose one of these options:
● 8-bit readout (0-255) — sets the controls to use 8 bits of tonal
resolution per color
● 10-bit readout (0-1023) — sets the controls to use 10 bits of tonal
resolution per color
● 12-bit readout (0-4095) — sets the controls to use 12 bits of tonal
resolution per color
● 16-bit readout (0-65535) — sets the controls to use 16 bits of tonal
resolution per color
