A couple months ago (sad but true), Fabrice passed on (https://mailman.ntg.nl/pipermail/ntg-pdftex/2016-January/004066.html) the report from Denis (https://groups.google.com/forum/#!topic/comp.text.pdf/ZnobgbiiDZ4) that pdftex creates pdfs with "No document catalog dictionary" and this fails jhove validation.

But then, running the pdf through pdftk these.pdf output valid-these.pdf makes it pass.

More details and a test document apparently at http://tex.stackexchange.com/questions/79947 Except that report implies that maybe this is about the EOL silliness that was fixed a couple years ago?

So, Denis, can you confirm that pdftex from TL'15 still does not generate good pdfs for you? (I imagine you are using the latest pdftex, but just in case ...)

As you've seen, the trouble seems to come more from JHOVE than LaTeX but:

- nevertheless, it turns out that all the files I tested with the current TL 2015 which are considered as invalid from JHOVE point of view become valid as soon as `\pdfobjcompresslevel 0' is added before `\documentclass', - I'm interested in testing the new primitives described by Akira. So I ran: - `rsync -a --delete --exclude=.svn tug.org::tldevsrc ~/texlive-svn/' - `~/texlive-svn/Master/bin/i386-linux/pdflatex file' for a file containing `\pdfsuppressptexinfo 0' before `\documentclass' but this failed with: ┌──── │ ! Undefined control sequence. │ l.2 \pdfsuppressptexinfo │ 0 └──── What am I doing wrong?

Sorry for the delay. AFAICS with TL 2016, for passing successfully the JHOVE's validation test: - `\pdfobjcompresslevel 0' is necessary and sufficient, - `\pdfsuppressptexinfo 0' is harmless but hasn't any effect, which means that if it is inserted at the very beginning of the `.tex' file: - without `\pdfobjcompresslevel 0', the test fails, - with `\pdfobjcompresslevel 0', the test doesn't fail. All the best. -- Denis
