7.5.a Editing the Step Tablet

Before you scan for the ﬁrst time, you must enter the step tablet values for

your transmissive calibration strip into the Step Tablet Values form.

Attached to the outside of your GS-800, you will ﬁnd a copy of the

manufacturer’s printout of the diffuse density values for each segment of

your transmissive step tablet, as well as a serial number that identiﬁes the

step tablet to which those density values belong. 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 can cause

signiﬁcant errors in the reported densities of your scans.

To enter the density values for your transmissive cal strip, select Transmissive

in the main acquistion window and click on the Edit Step Tablet button in the

Densitometer Options box.
