More Adobe Acrobat fun

 Working on remediating some PDF files and have been frustrated by random elements that the accessibility checker finds in the final review.

I know that these elements are not in the visible file, but they are often artifacts from the production process.

I found a shortcut today on the Adobe help site. Sharing for my own notes and to help this pop up for more people. 

Here is the key part:

"To try this out, do this:

• launch the Preflight tool (cmd-shift-X, or go to Edit->Preflight, or search for it in the Tools view
• switch to the "PDF Standards" library (pull-down menu in the middle at the top of the Preflight window)
• again, in the Preflight window, switch to the "Fixups" list (click on the wrench icon)
• in the search field in the Preflight window, enter 'artifact'
• an item with the name "Mark all non-structure elements as artifact" will be shown
• click on the "Fix" button in the lower right to execute the fixup (again: make sure to work on a copy of your precious original PDF, or during execution of the fixup, save to a different file name and/or different folder)

Once completed, all elements should either be part of the tagging structure, or be marked as artifact (background element)
