5.2.4
Daily Calibration without MBL (Exception)
In case of a daily calibration without MBL all used paper configurations must at least be
calibrated once with a PBL. Thereby you can use the test routine without laser point (with
the exception of the first time).
The daily calibration without MBL is only recommended in the following case:
When using paper types, which are quite different, at the same time, e.g. papers of
–
different manufacturers. In this case the MBL corrections cannot show exactly the
same effect for all papers.
A daily calibration based on PBL (without MBL) only makes sense in the following case:
Only one or only very few paper configurations are used.
–
If you use several paper configurations the daily calibration with MBL is more efficient.
5.2.5
Calibration of a New Paper Configuration in Case of Emulsion Changes or Changes in a Paper
Configuration (not Master Paper)
Note
If you are aiming at an extremely high print quality, the PBL should be printed with
laser point even in this case. However, the calibration process will then take longer
(approx. 10 minutes per paper configuration).
To ensure this high print quality the paper can be recalibrated with a PBL with laser
point about once every month.
Generally the use of a permanently higher print quality and the additional time
required for the calibration must be analyzed.
If quality problems occur in spite of a successful PBL (without laser point), a PBL with
laser point must be printed.

Printing an MBL Test
Print an MBL:
This provides for a calibrated condition of the
machine.
Print the PBL right after the MBL:
with laser point for new paper
configurations or for changes in the
paper configuration,
without laser point in case of
emulsion changes.
