Operating Manual

Dye strength: To start with, leave the value at 100%. Then, if a colorant
always seems to have a too high or low percentage in the recipe, you can
increase or decrease the dye strength. However, be very careful when
changing dye strengths!
Specific gravity:
If all the colorants (including transparent white) have about the same
specific gravity, the value can be left at 1. The optical data (absorption
and scattering) of the colorants are volume-related magnitudes but all
the program entries are mass-related (i.e. established by weighing).
For that reason, the specific gravity entry is necessary for the internal
conversion.
Concentration percentage in recipes:
The entries relate to the minimum and maximum permissible concentration
of the colorant in a recipe and are kept permanently for formulation.
If you have activated the Colorant Selection before recipe calculation
( see Section 22.2 «Formulation settings»), you can temporarily change
the entries made here ( see Section 5.2.6 «Entering a concentration
range»).
4. If you are dealing with an ink leftover, activate the Is leftover
check box. The designation of this colorant will then be marked with
a $ - sign in the Define Assortment: xxx window ( see Chapter 10
«Using ink leftovers»).
In the Available quantity field you can enter the existing quantity
of leftover.
5. Click on OK. The Measure colorant: xxx window appears.
In the selection field for concentration grades you can choose which
samples should be displayed.
If you click on New, you can define special samples in addition to
the standard samples. These samples are only valid for the selected
colorant.
If you click on a sample (concentration grade) and then on De-/Activate,
the sample is marked and no longer included in the calculation, for
as long as it remains deactivated.
