CHAPTER 2
– Measurement functions
In this example the measurement has been
taken on a Cyan patch. SpectroDens recog-
nizes the type of process color and displays
the
solid density
value of Cyan, which is dis-
played with the “C” symbol. Values for Cyan
(C), Magenta (M), Yellow (Y) and Black (K = key
color) can be shown.
The density value is a value without a unit.
It corresponds to the amount of ink applied
on the paper surface. The higher the density
value the higher the thickness of the ink layer.
The correct density value is dependent on
the printing parameters (paper, ink, printing
process). Usually, density values are between
1.00 and 2.00.
The second measurement has been taken on
a Magenta patch. The former Cyan measure-
ment still gets displayed. Measurements of a
specific process color will be overwritten as
soon as a new measurement of this specific
color will be made.

Description of the measurement functions
2.1 Measurement functions of SpectroDens Basic
Automatic Density
SpectroDens Basic comprises all functions related to density measurement. A very
practical feature is the
Automatic Density
mode. By a push of the green measure-
ment button the relevant measurement values are displayed. Depending on the type
of measurement patch this can be:
