Calibration Strip Window
When calibration is turned on, a calibration strip window will appear below the main
scanning window and the length of the main scanning window will be reduced to 29
cm reflective and 23 cm transmissive.
Every time the densitometer calibrates, an image of the calibration strip will appear in
the calibration strip window.
D.6.a Editing the Step Tablet
Before you can calibrate, you must enter the step tablet values for your transmissive
calibration strip into the Step Tablet Values form.
In the package with your calibration strip, you will find a printout of the diffuse
density values for each segment of your transmissive calibration strip. Those exact
density values must be entered into the computer for the software to associate a
correct density value with each step on the step tablet.
Note: Scanning in transmissive mode with incorrect step tablet values entered into the
form can cause significant errors in the reported densities of your scans.
To enter the density values for your step tablet, click on the Edit Step Tablet button in
the Densitometer Options box. The Step Tablet Values dialog box for the GS-700 will
open.
