dE GretagMacbeth (de GMB) is a quality criterion for using ink leftovers. Among other things, it<br />
takes into account the fact that it is very difficult to achieve a pure ink with a dirty ink leftover.<br />
1. Click in the Sorted according to field and then on the required option in the selection list.<br />
If you click on the Search button, the Search criteria window appears. This enables you to reduce<br />
the number of recipes displayed on the basis of various criteria.<br />
13.3 Processing an existing recipe<br />
You can correct an existing recipe (e.g. you can modify the designation or the additional<br />
description).<br />
1. Click on the recipe you want to process in the left area of the Database: Recipes window.<br />
2. Click on Modify. The Recipe Entry window appears.<br />
3. Click on the Designation or Additional description field in the Recipe entry window<br />
and make the desired entries.<br />
For changes in the Ink quantity and Ink film thickness values, it is best to load the recipe and<br />
then modify it ( see Section 5.5 «Modifying a recipe»). This gives you the chance to observe<br />
the effect of any changes (difference against the target color).<br />
13.4 Batch processing<br />
If an ink manufacturer has to replace a pigment he has been using hitherto with a new one, then<br />
all existing recipes produced using the assortment in question and containing the color in question<br />
will have to be recalculated using the substitute pigment.<br />
Batch processing means that this process of replacement and recalculation, which would otherwise<br />
have to be carried out manually, can be automated and therefore greatly accelerated.<br />
In a case like this, the ink manufacturer will create colorant calibrations for the color using the<br />
new pigment, enter these into the relevant assortment and then make the modified assortment<br />
available to those of his customers working with Ink Formulation.<br />
In an expanded search window, it is possible to filter out from all the saved recipes those containing<br />
the pigment which needs replacing, and to display them in a list.<br />
In a second stage, you can specify in detail the conditions under which the recalculation of these<br />
recipes should take place. For example, the recipes can be recalculated and optimized while<br />
leaving the other colors in the recipe untouched. This is especially useful if the color difference<br />
between the old and new pigments is only slight.<br />
