14.4.4 Calculating optical data
From the measurements (reflections), Ink Formulation calculates the optical
data of the colorant (absorption and scattering capacity). By means of
a theoretical back calculation to the color values of the individual samples,
a conclusion can be reached about the quality of the colorant calibration.
You can also check the effects, e.g. of a deactivated sample.
1. In the Define assortment: xxx window select the color for which
you want to check the optical data and click on Process.
2. If you wish, make the changes in the Measure color: xxx window
of which you want to check the effects.
If for example a sample causes a large color distance, select this one
and click on Deactivate. The sample will be marked and no longer
included in the calculation while it remains deactivated.
3. Click on Calculate.
In an information window Ink Formulation tells you the color distances
for the individual samples, together with the maximum and minimum
color distance of the colorant calibration.
14.4.5 Diagnosis
When the spectra are displayed you will at a glance have a good overview
of the quality of the colorant calibration which has been measured.
1. In the Define assortment: xxx window select the colorant
for which you want to check the spectra and click on Process.
2. Click on Diagnosis in the Measure colorant: xxx window.
In the key field on the right you can click on an entry to highlight the
relevant curve in color. By selecting the On white or On black option the
relevant curves are displayed.
