After the image is printed, the system will display all measured optical density

values:
0.19
0.50
1.30
Default densitometer
e.g. Macbeth TR924
The displayed values (that have to be monitored) represent the following steps on the
test film:
Operating Level
Base + Fog
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.
Refer to
page
local Agfa service organization.
Record the density levels on Chart 1 ('Drystar 5500/5503: Determination of
5
Operating Levels'). Refer to
page 247.
