6 Check the printed test film.
The test film should be similar to the image below.
Density response of Drystar media
Different densitometers can give different results for measuring the same
density area. This is due to spectral differences between the densitometers.
The density values used in this manual are based on the Macbeth TR924
densitometer. Values measured with another densitometer can vary from
these values.
Non-calibrated or badly calibrated densitometers can result in even larger
differences.
To give the user an idea of the differences given by the most frequently used
densitometers, you can find the measurements for an SMPTE pattern on the
Drystar DT 2 B and Drystar DT 2 C films in Appendix B.
The calibration film must be free of dust particles or any other artifacts. If
this is not the case, clean the print head (refer to ‘Print head cleaning’ on
page 107) and restart the calibration procedure.
In order to be usable this film should be absolutely dust free withinthe marked region!
