11-2 Calibration
Film calibration is the process of characterizing a given combination
of imager and
DirectVista
grayscale film to allow the imager to
compensate for imager-to-imager variation and supply
cassette-to-cassette variation.
When a
DirectVista
grayscale film cassett e is loaded into the imager
for the first time, the imager will print a test sheet and read that test
sheet with the built-in densitometer, then recalibrate based on the
results.
You can also perform a film calibration manually.
