From the developer:
PdfBoxEditor provides you a handy and powerful tool for editing, viewing and inspecting PDF boxes. Some typical tasks include: Before you submit your project to a printing company, you should thoroughly check if all required boxes are present in your ready-to-print PDF and if they align correctly with the printer's marks. When you receive PDF files for further processing, you have to get an overview of the boxes defined by other authors.
