Densities Cmyk - Techkon SpectroDens Manual

Densities CMYK

In the measurement function Densities CMYK all four partial densities for Cyan,
Magenta, Yellow and Black are displayed.
Patch for reference measurement
Patch for sample measurement
Manual TECHKON SpectroDens Chapter 2 – Measurement functions
In this example, a solid Magenta patch was
measured. The solid density is:
M = 1,42.
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
densities. No printing ink is 100 % spectrally
pure. There will always be partial colors
besides the actual main color.
In this measurement function measurements
can be compared to reference values as well.
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 (difference
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
selecting the triangle symbol.
The function Densities CMYK is especially
suitable for the measurement of multicolored
composed CMYK colors, e.g. in logos, to find
out the reason for possible color shifts.
