d-lab.2, d-lab.2plus, netlab.2plus: Operation
FastMBL Test
A FastMBL can be started as soon as the last print of a running order is in the Paper
Processor. Only one MBL test print will be printed and measured. A calculation and
correction of the "Master Balance" is made if the measuring results are within a certain
allowable deviation. There is no further print for checking, however, the result is added to
all papers (unless in tolerance) just as in a "normal" MBL.
A message will be created if the results of the FastMBL are not within the expected
correction range. In this case the deviation is too high to get all measuring fields back in
tolerance with only one iteration process. In this case a "normal" MBL must be printed to
get the production back into a neutral range.

Calibrating the Scanner (Pixel Correction, PIKO)
Applies only to d-lab.2/2plus
The pixel correction calibrates the light path of the lamp all the way to the CCD. It is
required for the following jobs:
Balancing the pixel sensitivity of the CCD (for each single pixel).
–
Defining the illumination intensity (influenced by lamp, filter, mirror box, film carrier),
–
e.g. in case of lamp replacement.
To define the window of the inserted film carrier (illumination on the CCD chip).
–
The pixel sensitivity varies, among others, with the temperature of the CCD chip and with
brightness. For this reason, the PIKO is executed automatically in the following cases:
Machine startup
–
(Whereby any film carrier may be inserted when the machine is started.)
Film carrier change
–
changing from negative film to slide and vice versa
–
Major light and temperature fluctuations (light path / CCD)
–
Manual PIKO is only required if it was not terminated correctly. This may happen if there
were particles in the light path, e.g. paper , film, or the film carrier is not correctly
inserted.
Starting the PIKO manually

Start FastMBL
Film carrier must be inserted and empty.
Insert a film carrier (if not done before) and
remove / eject film if necessary.
