b. Formulation settings
Check the formulation settings, ( see Section 22.2 «Formulation settings»). Certain inputs
(e.g. ink film thickness) can have a considerable effect on the recipe calculation.
c. Ink Quantity
In the Ink Quantity field, you can enter the desired quantity by overwriting the field or by clicking
on the pushbutton with the arrow symbol to increase or decrease the value indicated. You can
also calculate the ink quantity after formulation to suit your print job ( see Section 5.3
«Calculating the ink quantity»).
d. Use of ink leftovers
If you want to make use of leftovers, activate the Use of ink leftovers check box (
Chapter 10 «Using ink leftovers»).

5.2.3 Defining a target color
General
Ink Formulation allows you not only to take proper account of the differing properties of the substrates
for the target color and the recipe, but even to select an assortment for the formulation
which differs in its surface properties from the recipe substrate which is to be printed. However,
to do this the user must give the system the correct information about the substrate properties
during the formulation process.
Below are some examples of possible combinations.
Example 1:
Target color on uncoated paper, recipe on coated paper using an assortment on coated paper.
Example 2:
Target color on uncoated paper, recipe on transparent film using an assortment on transparent
film or on painted Leneta cards.
Example 3:
Target color on uncoated paper, recipe on reflective metalized film using an assortment on metalized
film or on painted Leneta cards.
In principle, any combination of the following substrates is possible:
• Paper, coated or uncoated or opaque film
• Transparent film
• Metalized film (provided the measurement geometry is Diffus/8°(D8i)).
This considerable flexibility requires, however, that, for the filter settings Pol (for instruments with
measurement geometry 45°/0°) and D8i (for instruments with measurement geometry Diffus/8°),
with certain combinations of substrates Ink Formulation has to make some compensation in the
filter settings, in order to achieve a good visual match between the target color and the recipe.
