Recently I have visited a demo of the PACKZ PDF Editor. PACKZ is developed by the workflow specialist Hybrid Software where a lot collaborators are former employees of Artwork Systems and Esko. This professional (and expensive!) PDF editor is dedicated to packaging files. In addition of editing existing and adding new page objects, one can automatically and manually create traps and impose packaging files based on CAD data.
I had a good impression of the PACKZ features. However it’s very strange that the application is not capable to export PDF/X files!
