7 Check the printed test film.
The test film must be similar to the image below.
Density response of Drystar media
Different densitometers can give different results when 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 X_Rite 310
densitometer. Values measured with another densitometer can vary from
these values.
It’s possible to change the default densitometer. Refer to Changing general
image quality settings - Default densitometer on page 93. You can also
compare the density values from different densitometers with each other.
Refer to ‘Drystar media density response data’ on page 237.
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, DRYSTAR DT 2 C and DRYSTAR DT 2 Mammo films in
Appendix B on page 237.
The calibration film must be free of dust particles or any other artifacts. If
this is not the case, clean the print head and restart the calibration
procedure.
