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: q 8-bit readout (0-255) - sets the controls to use 8 bits of tonal resolution per color q 10-bit readout (0-1023) - sets the controls to use 10 bits of tonal resolution per color q 12-bit readout (0-4095) - sets the controls to use 12 bits of tonal resolution per color q 16-bit readout (0-65535) - sets the controls to use 16 bits of tonal resolution per color Scanning from HP PrecisionScan Pro 63

resolution per color
