Note that there is a free and very good PDF accessibility checker: http://www.access-for-all.ch/en/pdf-lab/pdf-accessibility-checker-pac.html You can easily generate a detailed report with this tool. It does, however, not check for PDF/A-1a conformance. Cheers, Christoph --f46d04426f188ad73c0519ca297a Content-Type: text/html; charset=UTF-8 Content-Transfer-Encoding: quoted-printable

Thank you for the report .
It would be nice to have a pdf made by context using \nopdfcompression
that have all these issues together with the report emitted by acrobat.
Last time I have checked a pfd/a-1a made by context it was all ok, but it was time ago and maybe not
all the features were tested deeply.

Hello and thank you for raising t= hese issues.

Note that there is a free and very go= od PDF accessibility checker:
You can e= asily generate a detailed report with this tool. It does, however, not chec= k for PDF/A-1a conformance.
