Hi there!
I've just redone a brochure in Affinity Publisher originally produced at my agency using Indesign. The process of creating the layout was smooth, but the export to PDF/X3 wasn't: Either parts of the text got rasterized or some images were missing in the exported PDF.
When using the preset "Export (web)" some headlines and parts of the copy text got rasterized without any apparent reason (see page 10 + 11, no fx, fonts embedded). If exported to web with the option "don't raster anything" set the same headlines and copy text got exported just fine as vectors - but some images were missing afterwards (afphoto format).
Just wonder what I was doing wrong?
Best, Volker
