In DELTA Mode (= comparison mode)
the measured values are compared to
reference values. The mode is activated
by navigating to the "soft key" with the
triangle symbol and selecting it.
In the example on the left side a Yellow patch
was measured.
The measured solid density is:
Y = 1,37
This is 0,08 less then the set reference
(= target) density of Y = 1,45.
The measured value is outside the limits of
1 2
the set tolerance of ± 0,06.Therefore it is
marked with a cross symbol in the round
K C M Y SLUR C+M K C M Y 80% 40% BAL
icon.
A checkmark symbol would be shown in case
of a measurement within the tolerance limits.
The setting of reference values and toler-
ances is done in the menu under the item
measurement conditions.
In the Density Reference Setup up to five
data sets (REF 1 – 5) for reference (= target)
densities can be edited.
As a preference the reference densities
recommended by the German Printing and
Media Association (bvdm) for the five defined
paper classes are already pre-set.
The tolerances define the lower and upper
limits around the reference values. In this
example for Yellow:
1,45 + 0,06 = 1,51
1,45 - 0,06 = 1,39
