GS-710 Imaging Densitometer
6-13
Diffuse density values are converted to specular optical density units
according to the following formula:
6.5.b Calibration Settings
After you have entered the step tablet values, you can immediately calibrate
by clicking on the Calibrate Now button (in the Densitometer Options dialog
box).
You can also specify how often you want the GS-710 to automatically
recalibrate. Either click on the Calibrate Before Every Scan checkbox or enter a
Recalibration Interval (in minutes) in the appropriate field.
Note: The scanner will automatically recalibrate each time you change your
filter or your reflective/transmissive setting. (If you select a different
application with the same filter and light settings, it will not auto
recalibrate.)
Calibration Report
To print out a calibration report each time the densitometer calibrates, click on
the Calibration Report checkbox.
6.6 Acquire the Image
Note: Before scanning in transmissive mode, make sure the white balance
region of the scanning area is not covered or obstructed in any way.
To begin to scan, click on the Acquire button. The scanned image will begin to
appear in the scanning window, line by line.
To interrupt a scan, click on the Stop button. A message will ask you to
confirm the interrupt, and then you will be asked if you want to keep the
partial scan. This feature is useful if you overestimated the size of the area
you selected.
