Pantonefarbfelder zu CMYK umwandeln

Hi @corai here is a quick script that may help. You must configure it by editing the `conversions` object, which I hope will be understandable. You can open multiple files before running the script. Let me know if it helps.

Edit: typo.

Eventuell geht das in der InDesign Druckfarbenverwaltung schneller, aber wenn wirklich die Illu-Dateien geändert werden sollen:

Farbfelder bearbeiten, jeweils in Prozessfarbe ändern und Werte eintragen.
