How can I prevent Adobe Acrobat from applying optimizations and compressionsserve on save/save as...

Sep 20, 2013 9:57 AM

I am generating mailpiece documents as PDF v1.4 from a document composition tool.  I am using Enfocus Pitstop v10 (v10.1.7.27 to be exact) to remove some unneeded water marks from the produced document.


My issue is that I need to PRESERVE the original PDF structure as emitted from my composiiton tool and I'm finding that regardless how I proceed, Adobe Acrobat want to resave the PDF as v1.6 and apply a series of optimizations and compressions which alters the original PDF structure.  The reason I need to preserve the strucure of thePDF is to confirm 508 compliance for the emitted PDF documents.


Note: I've tried various settings in Acrobat Distiller and the Adobe PD printer (thinking they are invoked somewhere inthe backgroud of Acrobat when it goes to save/save as...) but haven't experienced any progress...


Am I chasing a rabbit here (meaning what I want is NOT possible) or am I missing something in my configuration attempts??

    If you need the final PDF to have the requisite well-formed structure tree (that is, compliant with ISO 14289-1, PDF/UA-1) and thus "accessible" then you need to do the adjustments to your PDF's content streams before establishing that well-formed structure tree.

    Note that PDF  versions 1.4 or above can have that well-formed structure tree - put another way PDF version 1.4 or PDF-1 (PDF is the ISO Standard ISO 32000-1) can have the well-formed structure tree. I can 'build' such a PDF that starts as PDF version 1.4 via Acrobat 5, do some additional post-processing with Acrobat XI Pro which, via a Save As puts the PDF into a new "version" and *not* adversely affect content streams / structure tree.  Your post-processing is what is changing the "guts" not the save to a different version.

    You can use Acrobat Pro to save to whatever version of PDF/A you need. If anything in particular is forbidden in PDF/A it will convert it.
