niklaskoelln Posted October 31, 2023 Share Posted October 31, 2023 Hello everyone, I have a problem with Affinity Publisher’s PDF export that makes it virtually impossible to generate print-ready PDFs. The images in my exported PDFs often—though not always—appear “glitched”, with distorted or black bars appearing mostly in the upper half of the image. I have included a comparison screenshot that shows you the faulty result of the PDF export vs. how it should look like. I have also attached both the faulty and correct PDF. I do not know exactly what causes this problem to happen, but here is everything you might need to know about it: I only encounter this problem on my Macbook Pro (2021) with M1 Max. When I export the same document through Intel-based Macs or Windows machines, the problem does not occur. I’m running the latest version of macOS and Publisher 2.2.1. However, I’ve had this problem ever since I got this Macbook in late 2021, meaning this problem also existed in Publisher 1.x (I finally got around to posting this here 🫠) Not all images are affected. On some documents, none are affected at all. I played around with the PDF export settings quite a bit and different settings do lead to different results. Exporting a PDF for screens, for example, made the problem go away … but only on one document that I tested. Weird. My guess would be that this problem is caused by PDFlib, which to my understanding is the library used by Publisher to generate PDFs on macOS. Maybe there is a bug related to PDFlib on certain Apple Silicon machines? Though the problem might be something completely different and this may just be a shot in the dark. Any help on this is greatly appreciated! Right now, I have to export any PDF that I need to have printed through my secondary Windows machine, which is obviously far from ideal. Thank you, Niklas correct.pdf faulty.pdf Quote Link to comment Share on other sites More sharing options...

If fiddling with the hardware setting does not help, try if running the app in Rosetta mode does. Quote Link to comment Share on other sites More sharing options...

This seems to have fixed it, thank you! Still curious why this problem exists, I hope the devs will eventually find a fix for this 😅 thomaso 1 Quote Link to comment Share on other sites More sharing options...
