In this example, a solid Magenta patch was
measured. The solid density is:
M = 1.47
But why are densities for the other colors
shown as well ? Shouldn’t they have a value of
0 ? No. These are the so-called partial densi-
ties. No printing ink is 100 % spectrally pure.
There will always be partial colors besides the
actual main color.
This function also makes comparison be-
tween measurements and reference values.
In this example the reference value was not
taken from the reference memory but was
measured just before by putting the “soft key”
to Reference:
1. First select via “soft key” Reference and
make a measurement on a patch which will
be the future reference patch.
2. Now activate via “soft key“ Sample and
make a measurement on a sample patch. A
triangle symbol in front of the measurement
value indicates that delta values (dierence
between reference and sample) are shown.
Future sample measurements will be com-
pared to the once measured reference values
as well.
3. Now activate the DELTA Mode by select-
ing the triangle symbol.
The function Densities CMYK is especially
suitable for the measurement of multicolored
composed CMYK colors, e. g. in logos, to nd
out the reason for possible color shifts.
For information about the ∆Dmax-function

Densities CMYK
In the measurement function Densities CMYK all four partial densities for Cyan, Ma-
genta, Yellow and Black are displayed.
