Maintaining Optimal Image Quality - AGFA Drystar 5500 Reference Manual

Maintaining optimal Image Quality

Calibration is necessary to maintain optimal Image Quality. This is required in
the following situations:
• Before initial use of a film,
• When a media with different batch number is loaded,
• After a certain number of copies have been printed,
• After the replacement of the thermal head.
Topics:
• Overview of calibration functions
• Understanding the calibration policy and the calibration initiation
Overview of calibration functions
Three calibration functions are provided for the printer.
Calibration
1 'Film calibra-
tion'
2 'Print head
cleaning'
3 'Print head
profile cali-
bration'

Purpose
• To measure and set the sys-
tem density of the printer.
• To measure and set the film
sensitometry values.
To eliminate white dots or lines
in transport direction.
To reduce vertical density irreg-
ularities on the film.
WARNING:
Some calibration functions are interrelated, so do not perform
any of the above calibration functions as an isolated procedure.
Note: Before performing a calibration, read the general
guidelines as described in 'Understanding the calibration policy
and the calibration initiation'.
