Back to TOC 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 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: l 8-bit readout (0-255) - sets the controls to use 8 bits of tonal resolution per color l 10-bit readout (0-1023) - sets the controls to use 10 bits of tonal resolution per color l 12-bit readout (0-4095) - sets the controls to use 12 bits of tonal resolution per color l 16-bit readout (0-65535) - sets the controls to use 16 bits of tonal resolution per color Scanning from HP Precisionscan Pro 71 Scanning from other programs (TWAIN) You can bring an image directly into an open file in one of your programs if the program is TWAIN-compliant. Generally, the program is compliant if it has a command such as "Acquire," "Scan," or "Import New Object." If you are unsure if the program is compliant or you do not know what the command is called, see the documentation for the program. When scanning from within a TWAIN-compliant program, the HP Precisionscan Pro software may start if the TWAIN-program allows it. If the HP Precisionscan Pro software starts, you can make changes to the image as you normally would. If not, the image returns to the TWAIN-program immediately. Tip If your program is not TWAIN-compliant, you can try to copy and paste or drag-and-drop the image into the program. Or, save the image as a file and then place the file in the program.

Scanning from HP Precisionscan Pro
71
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
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:
l
8-bit readout (0-255)
— sets the controls to use 8 bits of tonal
resolution per color
l
10-bit readout (0-1023)
— sets the controls to use 10 bits of tonal
resolution per color
l
12-bit readout (0-4095)
— sets the controls to use 12 bits of tonal
resolution per color
l
16-bit readout (0-65535)
— sets the controls to use 16 bits of tonal
resolution per color
Scanning from other programs (TWAIN)
You can bring an image directly into an open file in one of your
programs if the program is TWAIN-compliant. Generally, the program
is compliant if it has a command such as “Acquire,” “Scan,” or “Import
New Object.” If you are unsure if the program is compliant or you do
not know what the command is called, see the documentation for the
program.
When scanning from within a TWAIN-compliant program, the HP
Precisionscan Pro software may start if the TWAIN-program allows it. If
the HP Precisionscan Pro software starts, you can make changes to
the image as you normally would. If not, the image returns to the
TWAIN-program immediately.
Tip
If your program is not TWAIN-compliant, you can try
to copy and paste or drag-and-drop the image into
the program. Or, save the image as a file and then
place the file in the program.
