Densitometer, integrated
The integrated densitometer should allow an
automatic Setup routine for MBL, PBL and CBL.
The routine is repeated upon the Auto-Setup until
the test print values are in tolerance with the aim
densities.
The measuring values are compatible with those of
the DENS1, provided the calibration has been
performed with the same measuring plate.
Procedure:
A zeroing to D=0,10 in Y, M, C is performed
immediately before each measurement. For this, the
measuring head is pressed on the reference plate.
The actual measuring procedure is triggered by the
paper tip of the test print. The measuring head is
pressed on the test print, the measuring lamp is
switched on after 1 s and the preceding black/white
pattern is expected (only for MBL, PBL, CBL) prior
to the test print. If the pattern is not recognised after
15 s the latest, an error message is displayed.
After the correct detection of the preceding pattern,
the measuring phase starts. One measurement
each is performed in cycles every 20 ms for Y, M, C
until the end of the measuring field is reached. The
maximum value is calculated for each colour.
Measuring values differing by more than 0,4 from
the maximum value are eliminated; the remaining
values are used to calculate the mean value.
After the measurement, the measuring lamp is
switched off and the measuring head is lifted.
An error message appears if the measuring lamp
fails.
