Hello, You might want to take a look at the Ghent Work Group (www.gwg.org), they have some useful documentation. While it might not cover all of what you need, it is a good resource nonetheless. https://gwg.org/technical-specifications/gwg-2015-specifications/ PDF Dev On Friday, February 14, 2025 at 07:35:13 AM GMT, Hiller, Gerhard <gerhard.hil...@msh.de> wrote: Hello everybody, we try to create a PDF/X4 document from scratch, currently only with some text. I thinkd pdfbox togegher with xmpbox But we are struggeling setting the right Metadata and XMP-Metadata to let it pass the preflight check in Adobe Acrobat Pro. As PDF/x4 is an ISO Spec, no free available description of the necessary metadata is available, at least we didn’t find it. Is there any known freely available documentation for that? Or can anybody point us to some code examples with pdfbox ? Have a nice day! Gerhard |
