Re: PDF: Parts Of Manually Tagged PDF Don't Show Up For Screen Reader

PAC will report if there is any untagged content that has not been artifacted and it will show you where it is. However, PAC can't fix anything.

It is possible that the missing content has been tagged, but it is in the wrong place in the reading order. If you don't have Acrobat, you would have to read the whole document to find out. If the document was created using Word, this is unlikely unless the missing content is in textboxes, in which case their position in the reading order depends on which paragraphs they are anchored to.

I would be happy to take a look if you want to send me the PDF.

" There are frustrating "ghosts in the machine" stuff with PDFs"

I second what Jon said, there are some unfortunate "glitches" that pop up with PDFs and can be difficult to fix.

One option would be to clear the structure and start again to see if it behaves differently, or re-type the content and create a new PDF. I have had success with some more expensive products (Like CommonLook's Integrity Validator), but have yet to see the cheap or free tool that can find and correct these issues without a lot of technical knowledge.
