The maximum permitted Color
Difference
∆
E is determined
for each print job. If the value
of
∆
E best is greater that the
specified
∆
E, you cannot achieve
the desired color quality by
changing the density.
For more information on printing,
please refer to Chapter 2.4.1.5
Printing the Measurement Values.
3.1.4 Interpreting the Measurement Results
Here we measure a second shade of green, for example, which
has as its Density D a value of 1.76 at 640 nm. Below this you
can see the recommended Correction cor needed to achieve
optimum results: in relation to the reference color you should
correct the Density D by -0.31/-26% in order to achieve the
closest possible match with the target color.
The color difference ∆E akt indicates how close the current
color is to the desired target color. In our example ∆E akt is 6.86.
If you implement the recommended changes to the density, you
can achieve a color difference of ∆E best as the Best Match
(optimum possible match). In our example ∆E best is 0.14.
You can print this measurement result by selecting
the Print icon.
