Changing the Maximum Densities of a Paper
The function with laser point must be activated in the screen Print PBL. Now the
maximum densities (Dmax) for the three color channels can be entered for the selected
paper configurations. The entered Dmax values are used to determine the maximum
intensity of the laser.
Thereby the following facts should be considered:
The maximum intensity of the laser is only determined by means of a PBL with laser
–
point. In case of a PBL without laser point the settings for the Dmax densities have no
effect.
The maximum densities of the three channels are not completely independent of each
–
other due to the color dyes in the paper. If the maximum density of one channel is
changed this also has an effect on the maximum densities of the other channels.
The specified Dmax values refer to measuring results with the internal densitometer.
–
If a paper is to be calibrated and the maximum densities of the PBL on this paper are
not as expected, an external densitometer must be used to measure this print. In this
case we recommend a device with Status A characteristics (e.g. the X-Rite
Densitometer).
Due to the deviating filters of the densitometer integrated in the Minilab, the required
nominal values (Status A) of the maximum densities cannot be entered directly in the
screen Print PBL. To determine the values to be entered proceed according to the
description on the following page.
For external measuring of the test strip always the same densitometer must be used.
