QuarkXPress 2016 and PDF/X-4

Hi all,

yesterday PDF Aktuell posted this blog entry:

During the preparation of the PDFX-ready settings and recipes for the PDF/X-4 export out of QuarkXPress we have recognized that QuarkXPress 2015 and 2016 do not write a GTS_PDFXVersion entry into the PDF. (See Acrobat menu File > Properties… > Custom.)

A preflight with the PDFX-ready profiles generates an error message since we check this entry. When creating PDF/X-1a files Quark is correctly writing this information into the PDF. All other PDF/X creator I am aware do also write this entry in their PDF/X files.

This is the reason that we have decided not to publish the PDFX-ready settings and recipes for the PDF/X-4 export out of QuarkXPress yet until Quark has solved the problem.

Unfortunately that reads as if QuarkXPress doesn't create correct, ISO compliant PDF/X-4.

Here's the comment I posted (which still seems to be in moderation queue):

Hi Stephan,

unfortunately that is not completely correct, as QuarkXPress DOES write the entry GTS_PDFXVersion into the X4 and exactly there, where ISO requires it (which is within the XMP meta data).

Therefore Acrobat certifies PDF/X-4 out of QuarkXPress 2015/2016 as standards compliant PDF/X-4 files.

Where your observation is correct is that QuarkXPress 2015/2016 does NOT write an ADDITIONAL entry about PDF/X-4 version complacency into the Document Information Dictionary. This is what you see when you – as you write – look at File > Properties > Custom in Acrobat and what the pdfxready profiles seem to check.

ISO states, that that this entry IS ALLOWED in X4 BUT NOT REQUIRED. Whereas in PDF/X-1a and /X-3 this entry IS the relevant entry, so there’s a significant difference between X1/3 and X4.

Where you are correct is that most applications capable of exporting PDF/X-4 do write this redundant entry into the Document Information. That’s why we are currently evaluating with our OEM partner who does these checks for us, whether we can add this additional entry in future updates, so that the current pdfxready profiles will work too.

Bottomline: QuarkXPress 2015/206 exports ISO compliant PDF/X-4 files and that’s what Acrobat as well as callas’ pdfToolbox also confirm.

Best regards

So to cut a long story short:
QuarkXPress 2015/2016 writes ISO compliant PDF/X-4, which Acrobat's PDF/X-4 preflight check verifies.

And in a future update we will add the legacy flag that some users or software preflights seem to still check, though ISO doesn't require it.
We highly value the work of pdfxready and Stephan Jaeggi and would love their profiles to also validate QuarkXPress 2016.

Feel there should be more chatting, more tips, more user interaction?

Thanks, Matthias.

First thing I did with QXP 2016 was run a check in Acrobat and QXP passed with flying colors.
