AGFA Drystar 4500 Reference Manual page 137

After the image is printed, the system will display the optical density values:
4
0.19
0.36
1.14
Default densitometer
e.g. Macbeth TR924
The displayed values represent the following steps on the test film:
Low density
Mid density
High density
If the mid density value does not meet or exceeds the recommended
values, the cause must be found and the problem solved before any further
clinical films can be printed.
