Disastrous PDF/X-4 compatibility
with new Affinity Publisher

24. July 201911. July 2019 by Stephan Jaeggi

The final version 1.7.1 of Affinity Publisher has recently been released. In the media, this program has already been considered an InDesign killer. The feature overview is indeed very promising. Regarding PDF/X support, the following statement is made on the website:

«You can also open, edit and output PDF/X files.»

Two years ago this claim was already made for the vector graphics program Affinity Designer 1.4. Then I tested Affinity Designer 1.4 using the Ghent PDF Output Suite 5.0, the internationally recognized standard test for PDF/X compatibility. The result with Affinity Designer 1.4 was disappointing. I was curious to see if the new Affinity Publisher – a multi-page layout program where secure PDF import and export is even more important than for a vector graphics program – would now have better compatibility with PDF/X-4 files.

The PDF Association has published a new guideline for the technically correct creation of accessible documents. The manual, entitled Tagged PDF Best Practice Guide: Syntax, is intended primarily for developers. It is intended to help developers understand the syntactic properties tagged PDFs need to meet accessibility requirements.

The guide is intended for interested parties who want to prepare accessible PDF documents in detail. On 70 pages, aspects such as PDF/UA as the standard for accessible PDF documents and general regulations are explained. In addition, developers and experienced users are provided with examples of the standard structure types and important information about attributes as well as properties, text features and other properties of PDF.
