Check and correct reading order
You can quickly check the reading order of tagged PDFs by using the TouchUp Reading Order tool. You can also use
this tool to add alternate text to images and correct many types of tagging problems that are outlined in the report
that Acrobat generates when you add tags to a PDF.
Reading-order problems are readily apparent when you use the TouchUp Reading Order tool. Each section of
contiguous page content appears as a separate highlighted region and is numbered according to its placement in the
reading order. Within each region, text is ordered left to right and top to bottom. (You can change this order in the
TouchUp preferences.) If a single highlighted region contains two columns of text or text that won’t flow normally,
divide the region into parts that can be reordered. Because highlighted regions are rectangular, they may overlap
somewhat, especially if their page content is irregularly shaped. Unless page content overlaps or is contained within
two highlighted regions, no reading order problem is indicated. Page content should belong to no more than one
highlighted region.
You can change the reading order of the highlighted regions by moving an item in the Order tab or by dragging it on
the page in the document pane. By reordering highlighted regions on the page, you can make a figure and caption
read at the specific point that they are referenced in the text. By changing the order of a highlighted region, you effec­
tively change the reading order of that item without changing the actual appearance of the PDF.
