Remove page elements from the tag structure
When tagging a PDF, Acrobat can’t always distinguish between instructive figures and decorative page elements. Items
that visually enhance page layout, such as decorative borders, lines, or background elements, can add clutter to the
structure layout and should be removed. Therefore, Acrobat may incorrectly tag artifacts or page elements as figure
tags. You can remove artifacts and irrelevant page elements from the tag structure by redefining them with the
Background tag or by deleting their tags. If a tagged image in the document doesn’t contain useful or illustrative
information for the user, you can remove the element from the tagging structure so that it isn’t read out loud or
reflowed.
1 Select the Touch Up Reading Order tool.
2 In the Touch Up Reading Order dialog box, select Show Page Content Groups, and click Page Content Order. Then,
select Show Tables And Figures.
3 Remove the page element by doing one of the following:
• In the document pane, select the page element, and then click Background in the dialog box.
• In the Order panel, select the page element, and then press Delete.
Edit tags for figures and tables (Acrobat Pro)
You can use the Touch Up Reading Order tool to add and edit tags and alternate text for figures and tables.
Apply a figure tag
You can select an element and define it as a figure by using the Touch Up Reading Order tool. Once you define it as a
figure, you can add alternate text to describe the figure.
1 Using the Touch Up Reading Order tool, select the figure.
2 In the Touch Up Reading Order dialog box, click Figure.
3 In the document pane, right-click the region and choose Edit Alternate Text.
4 Enter alternate text, and click OK.
Check and correct figure tags
You can use the Touch Up Reading Order tool to identify and correct tagging results for figures. Determine whether
figures include or require alternate text necessary to be read correctly with assistive technologies. Ideally, figure tags
should identify image content that is meaningful to the document as a whole, such as graphs or illustrative photographs.
If background elements that shouldn’t be read are tagged as figures, redefine them as background.
1 Select the Touch Up Reading Order tool, and then click Show Tables And Figures in the dialog box.
2 Do any of the following:
• If a figure isn’t tagged as a figure, select the content region you want, and then click Figure or Figure/Caption in
the dialog box.
• To remove text that was incorrectly combined with a figure, drag to select the text, and click the Text button in
the dialog box.
• To include a caption that is grouped with the figure, select the figure and caption, and click the Figure/Caption
button in the dialog box.
