Converting to PDF/A using -dPDFACompatibilityPolicy=2 returns without error but produces invalid PDF/A files

Hi,

it's me again... To test the Ghostscript PDF/A conversion I downloaded the Isartor Test Suite from here: http://www.pdfa.org/2011/08/isartor-test-suite/
I converted all PDF files using the following command line:

gswin64c.exe -dPDFA=1 -dBATCH -dNOPAUSE -sProcessColorModel=DeviceRGB -dColorConversionStrategy=/DeviceRGB -dCompatibilityLevel=1.7 -sDEVICE=pdfwrite -dNOOUTERSAVE -dNumRenderingThreads=8 -dPDFACompatibilityPolicy=2 -sOutputFile="%{outputfilepath}" "%{inputfilepath}" PDFA_def.ps

Of the 203 test files (I left out one with 10000 pages) all were processed without Ghostscript aborting, although two gave out warnings during conversion.
But 19 of the resulting files are not valid PDF/A (tested with PDFBox Preflight 2.00 RC3 and veraPDF)

Here are the names of the files and the reported PDF/A violations:

isartor-6-2-3-3-t01-fail-a.pdf

isartor-6-6-1-t01-fail-a.pdf
Action is forbidden, The action Launch is forbidden

isartor-6-6-1-t02-fail-a.pdf
Action is forbidden, The action Launch is forbidden

That seem  to be seven different problems, probably in different versions.

I use the AdobeRGB1998 compatible ICC profile from http://www.freedesktop.org/wiki/OpenIcc/ and the "default" PDFA_def.ps with output intent AdobeRGB1998.

I realize that some of the test files use somewhat obscure corner cases, but some like the "Launch" action are a bit more common, I think. Even so, I'd expect Ghostscript to produce valid PDF/A (best case) or abort (worst case).

Thanks.


Kind Regards
