The
TouchUp Reading Order tool provides the easiest and quickest way
to fix reading order and basic tagging problems. When you select
the TouchUp Reading Order tool, a dialog box opens that lets you
see overlay highlights that show the order of page content. Each
highlighted region is numbered and highlighted with gray or colored
blocks; the number indicates the region’s placement in the page’s
reading order. After you check the reading order of the page, you
can correct other, more subtle tagging issues as needed.
The TouchUp Reading Order tool is intended for repairing PDFs
that were tagged using Acrobat, not for repairing PDFs that were
tagged during conversion from an authoring application. Whenever
possible, you should return to the source file and add accessibility
features in the authoring application. Repairing the original file
ensures that you don’t have to repeatedly touch up future iterations
of the PDF in Acrobat.
You use the TouchUp Reading Order tool to perform the following
accessibility tasks:
-
Visually check, and then repair, the reading order of
page content
-
Tag fillable form fields and their labels
-
Add alternate text to figures and descriptions to form fields
-
Fix the tagging of simple tables, and prepare complex tables
for more advanced manipulation in the logical structure tree
-
Remove nonessential content, such as ornamental page borders,
from the logical structure tree
To perform more advanced reading order and tagging tasks—such
as fixing complex tables, removing obsolete tags after you delete
pages, and adding alternate text to links—you need to use the Tags
tab, which contains an alternate set of tools and features for manipulating
PDF tags. For more information, see Edit tags with the Tags tab.
Do one of the following:-
Choose Advanced > Accessibility >
TouchUp Reading Order.
-
Choose Tools > Advanced Editing > TouchUp
Reading Order Tool.
-
Click the TouchUp Reading Order tool
button
in the Advanced Editing toolbar.
- Save the document (or
a copy of it) before you use the TouchUp Reading Order tool. You
can’t use Undo to reverse changes made with this tool, so reverting
to a saved document is the only way to undo such a change.
- Choose View > Page Display > Single Page, when
using the TouchUp Reading Order tool. When you click the Clear Structure
button, Acrobat clears tags from all visible pages—even pages that
are only partially visible.
You can select TouchUp Reading Order options
from the dialog box, from the pop-up menu that appears when you
right-click/Control-click a highlighted region, or from the Options
menu in the Order tab. The TouchUp Reading Order tool includes the
following options:
- Text
-
Tags the selection as text.
- Figure
-
Tags
the selection as a figure. Text contained within a figure tag is defined
as part of the image and is not read by screen readers.
- Form Field
-
Tags
the selection as a form field.
- Figure/Caption
-
Tags a selected figure and caption as a single tag. Any text contained
in the tag is defined as a caption. Useful for tagging photos and captions
and preventing caption text from being incorrectly added to adjacent text
blocks. Figures may require alternate text.
- Heading 1, Heading 2, Heading 3
-
Tags
the selection as a first, second, or third level heading tag. You
can convert heading tags to bookmarks to help users navigate the
document.
- Table
-
Tags
the selection as a table after the selection is analyzed to determine the
location of headings, columns, and rows.
- Cell
-
Tags the selection as a table or header cell. Use this option
to merge cells that are incorrectly split.
- Formula
-
Tags the selection as a formula. Because speech software
may handle formula tags differently from normal text, you may want
to add a description using alternate text.
- Background
-
Tags
the selection as a background element, or artifact, removing the
item from the tag tree so that it doesn’t appear in the reflowed
document and isn’t read by screen readers.
- Table Inspector
-
Automatically analyzes the selected table into cells and
applies the appropriate tags. The table must be tagged as a table
before you can use the Table Inspector command on it.
- Show Page Content Order
-
Shows content elements as highlighted areas that contain
numbers to indicate the reading order. Specify the highlight color
by clicking the color swatch.
- Show Table Cells
-
Highlights the content of individual table cells. Specify
the highlight color by clicking the color swatch.
- Show Tables And Figures
-
Outlines each table and figure with a crossed-out box. The
box also indicates whether the element includes alternate text.
Specify the box color by clicking the color swatch.
- Clear Page Structure
-
Removes the tagging structure from the page. Use this option
to start over and create a new structure if the existing structure
contains too many problems.
- Show Order Panel
-
Opens the Order tab to allow you to reorder highlighted content.

table properties that is read by a screen reader or other assistive
technology.
