Solely for my own benefit, some updates to how to create PDFs from Latex/Overleaf that meet the PDF/A standard required by various publishers, whose own instructions miss out several important features.
- The final missing piece: make sure that hyperref receives the pdfa option. In particular, if you are using acmclass call it with
\documentclass[pdfa]{acmart}
Or similar adaptation, e.g., \documentclass[sigconf, nonacm, pdfa]{acmart}. Yes, I'm looking at you, PVLDB.
Throw in
\usepackage[a-2b]{pdfx}
I've no idea if this does anything useful, but why not?
Go back to your plots in python, and make sure that Matplotlib is instructed to not use type 3 fonts. The correct answer is of course 42, as in
or something similar.import matplotlib matplotlib.rcParams['pdf.fonttype'] = 42 matplotlib.rcParams['ps.fonttype'] = 42
Hopefully that will do it. Web services like https://avepdf.com/pdfa-validation can be useful at debugging things, if you don't mind uploading your documents to a random server, and running out of free goes.
