Re: PDF Reflow oddness in Adobe Acrobat/Reader

Hi Lisa, thanks - I don't have access to the original but removing the tags completely and adding them again does address the issue -- I guess that's why some folks automatically always remove tags from documents and just re-tag (if they don't have access to the source).

Hi Jonathan,

Interesting...PDF/A should lock the document (although you can get around it). Can you convert the Illustrator doc just to plain PDF? if so, do you see the same issues?

PDF/X is used usually (in my experience, others may vary) just for printing, so would it lock things down to keep the PDF 'pristine'?

The documents do have multiple layers and transparency - but turning those off and combining layers doesn't seem to solve the issue. In addition, the document tags and properties are editable - until reflow in Adobe Acrobat/Reader is enabled (although it doesn't reflow). Once reflow is enabled the document suddenly becomes not editable, the title can't be changed, tags can't be change and the items in the touch up reading order disappear from the reading order view. Any ideas? Initialization of reflow in Acrobat seems to trigger the document going into a different mode. The PDF seems to be in the PDF/X standard although converting to PDF/A doesn't seem to address the issue (unless the tags are removed and added).
