Operating Manual

1. Click on Solvent in the Set up assortment window.
The Solvent Entry window appears.
The Solvent button is only displayed if the Flexo/gravure printing
process was selected.
2. Enter the values determined in the Price, Specific gravity
and Viscosity fields.
14.4.7 Entering a viscosity (viscosity module only)
Following input of the viscosity curves for the inks and transparent white
(blend) of the assortment, the program is able to calculate recipes for
any desired target viscosities. It should be noted that a viscosity ( see
Section 24.3.7 «Viscosity in flexo and gravure printing») and a solvent are
assigned to every flexo/gravure printing assortment.
The proportion of solvent is determined by the program using quantity data.
This removes the conversion to percentages of the solvent proportion as
a source of error. The program provides information about the deviation
of the points entered from the theoretical curve.
1. Click on Viscosity in the Set up colorant window.
The Viscosity Entry window appears.
2. Enter your data in the Basic ink, Solvent and Viscosity fields.
In the top line, enter the quantity and the viscosity of the basic ink
(100% basic ink, 0% solvent). Enter further points for the relevant range
of viscosity underneath. The viscosity data for the solvent (0% basic
ink, 100% solvent) is entered in the Solvent Entry window ( see
Section 14.4.6 «Entering a solvent»). If the viscosity of the solvent is
specified there, two points are sufficient to determine the viscosity
curves of the inks. Otherwise at least three are required. However: the
more entries in the relevant range of viscosity the better.
