Sorry but I have to disagree that the Order Panel doesn't matter - it
certainly does for people who need to view documents in Reflow view, for
example people with various low vision conditions, not to mention the
reading order for PDFs viewed on many mobile devices.

The key to fixing it in Acrobat is to do the Order Panel first and then the
tags panel (changing the Order Panel affects both views whereas changing
reading order in the tags tree affects only the tags output).

The key to fixing it in InDesign is to go through each page working from
bottom right to top left and sending each frame in turn to the back in the
stacking order. This works perfectly in InDesign CS5.5 but for previous
versions it doesn't work for images which will still have to be fixed in
Acrobat as above.

While it is preferable to have both the Tags Panel and the Order Panel match
up, adaptive technology reads through the Tags Tree so making sure it is
correct is the goal. There are some documents where you simply can't get the
two to match up. There is also a bug when converting Word documents
containing images to tagged PDF where the images will always be placed at
the bottom of the page items in the Order Panel no matter where they are on
the page. The Tags will be correct but the Order Panel is "off."

As long as the Tags are correct and in the correct order, you should be
good.

Cheers, Karen

Subject: [WebAIM] tagging pdfs

I have a dilemma. I created a document in InDesign and tagged every header,
paragraph and photo. I then set the tags in the proper reading order and
export to a tagged pdf file. The tags come across perfectly and in the right
order. But when I look at the reading order panel, the order is off. Do
screen readers read the tags in the order they are listed in the tag panel
or do I need to go by what I see in the reading order panel, which is
different.
