PBL Test with Laser Point
The PBL test with laser point adjusts the maximum laser intensities for the three color
channels (red, green, blue). The adjustment is made by providing the maximum densities
(Dmax) (see
Changing the Maximum Densities of a Paper
The test routine adjusts the intensities by exposing the preset maximum densities on
paper without blooming effects.
If the option with laser point is selected the PBL is made in two steps:
1. Adjustment of the maximum laser intensity (maximum densities) by means of the test
prints graded densities and halo print.
2. Adjustment of the Printer to print a neutral grayscale. For this purpose the PBL test
print is printed several times (identical with PBL without the option with laser point).

Note
On principle all PBLs (on master paper or non-master paper) can be printed with the
option with laser point without any negative effects for the print quality. Actually this
option can be used in regular intervals to compensate for slight system fluctuations
which may occur over a longer period of time. This may help to provide for a more
consistent print quality. The calibration process itself, however, takes a little longer.
