This allows you to fix a few mistakes before the check up. If tags are missing, then they must be added. When tags are present, they should still be checked for correctness. Note: The automatic tagging feature may be sufficient on simple layouts, but it sometimes misinterprets the structure and reading order of complex page elements e. Therefore, you should still manually check the tags as explained below. Sometimes tagging can result in unexpected visual side effects, such as text disappearing behind background images.
The following steps can be taken to correct such side-effects:. Note: The order of items in the Content panel tree indicates their layer order in the document.
If item A is lower in the tree than item B, then if item A and B overlap in the document, A will be in front. Some people find this confusing, so a good way to remember how this works is to imagine putting documents in a pile and noting their names in a list.
The last document placed will be on top of the pile, covering the others, and its name will be on the bottom of the list. Sometimes it may not be clear by looking at content, what would be the most logical aural reading order.
In these cases, it is recommended to preview the reading order. Only readable text appears in the reflow view. If the tagged PDF does not reflow the way you want, it means that the content order or reading order of the PDF contains inconsistencies.
If this is the case, in addition to correcting the reading order, it may also be helpful to edit the document tags. Another way to test the aural accessibility of a document is to attempt to access the document with the screen readers that your readers will use e. It is important to set up the PDF correctly in order for assistive technologies e.
Screen readers read this text aloud to the user. For more information, see Create form fields. For information on setting the tab order to use document structure, see Set form field navigation.

Improve the accessibility of PDFs by adding tags in Acrobat. With a tagged PDF, the logical structure tree sends the contents to a screen reader or other assistive software or hardware in an appropriate order.
For best results, tag a document when converting it to PDF from an authoring application. Tagging during conversion enables the authoring application to draw from the paragraph styles or other structural information of the source document to produce a logical structure tree.
The logical structure tree reflects an accurate reading order and appropriate levels of tags. This tagging can more readily interpret the structure of complex layouts, such as embedded sidebars, closely spaced columns, irregular text alignment, and tables. Tagging during conversion can also properly tag the links, cross-references, bookmarks, and alternate text when available that are in the file. Acrobat analyzes the content of the PDF to interpret the individual page elements, their hierarchical structure, and the intended reading order of each page.
Then, it builds a tag tree that reflects that information. It also creates tags for any links, cross-references, and bookmarks that you added to the document in Acrobat. The Add Tags To Document command adequately tags most standard layouts. However, it cannot always correctly interpret the structure and reading order of complex page elements. Tagging these pages by using the Add Tags To Document command can result in improperly combined elements or out-of-sequence tags. These issues cause reading order problems in the PDF.
You can add a watermark to a tagged PDF without adding it to the tag tree. Once you have a tagged PDF, evaluate the document for reading order problems, tagging errors, and accessibility errors, and then repair them as needed.
Whichever method you use to tag the PDF, use Acrobat to touch up the tagging and reading order for complex page layouts or unusual page elements. It may incorrectly tag all of these elements as figures. Similarly, this command may erroneously tag graphical characters within text , such as drop caps, as figures instead of including them in the tag that represents the text block.
Such errors can clutter the tag tree and complicate the reading order that assistive technology relies on. If you tag a document from within Acrobat, the application generates an error report after it completes the tagging process.
Use this report as a guide to repair tagging problems. For example, if the web page relies on tables for its layout design, the HTML code for the table may not flow in the same logical reading order as a tagged PDF would require, even though the HTML code is sufficiently structured to display all the elements correctly in a browser.
Click on the Recognize Text button. Once the text is recognized, text can be corrected using the Correct Recognized Text from the Recognize Text dropdown list. NOTE : This typically only needs to be done if a document is scanned from a scanner or copier. Creating a PDF this way only takes an image of the document. If a document already has renderable text such as converting a Word document, you will not be able to Recognize Text function and should be fine.
The reading order helps to determine how the document looks depending on how it is viewed. For images in the document, each one should be set with Alternative Text Alt Text. This will allow you to set Alternative Text for each of the images one by one. If the image is informational, then a good description of the image should be entered. If the image is purely decorative such as a logo on the page , then the Decorative figure checkbox should be checked.
This will set the Alternative Text to be null and not be important to the person reading the document. If the document contains one or more tables, check the tables to make sure that header rows are properly marked.
To check the tables, do the following steps:. Look at the structure of the document visually to determine what the heading structure should be that makes the most sense for reading through the document. Keep in mind how a screen reader might read the document. Keep in mind the structure as the same as websites and documents of H1 through H6. The amount of information that is delivered to the memory buffer can affect how long Reader takes to perform tasks, such as opening the document, advancing to the next page, changing views, and carrying out commands.
When Reader sends only the currently visible pages of a PDF to the memory buffer, the assistive technology has access to those pages only. It cannot go to another page until the next page is visible and Reader has sent the page information to the memory buffer. Therefore, if this option is selected, you must use the navigation features of Reader, to navigate from page to page in the document.
Set the Default Page Layout option in preferences to Single Page if you choose to have Reader send only the currently visible pages to the assistive technology.
Because Reader sends page information about all visible pages, the assistive technology receives information about pages that is only partially visible such as the bottom of one page or the top of the next and those pages that are visible. If you use a page display setting other than Single Page , such as Continuous , and then you display the next page, the technology will not correctly track which portion of a previous page it has already read aloud.
Read The Entire Document: This option can be best if you use a screen reader that has its own navigation and search tools and that is more familiar to you than the tools in Acrobat. It allows Acrobat to deliver an entire small document but revert to page-by-page delivery for large documents. Confirm Before Tagging Documents: When selected, lets the user confirm the options that are used before Acrobat prepares an untagged document for reading.
Tagging can be a time-consuming procedure, especially for larger documents. You can choose to use the default voice or any of the voices that your operating system provides.
You can also use the up and down arrows to read blocks of text. These preferences do not have corresponding options in the Accessibility Setup Assistant. Keyboard shortcuts to mouse actions. Use a screen reader or magnifier. To verify your settings in Acrobat Reader:.
In the left pane, select Reading. Click OK. Activate or deactivate Read Out Loud. Read PDF form fields out loud. In the PDF form, press Tab to select the first form field. Make entries and selections as needed, and then press Tab to move to the next field, repeating this step until the form is completed. Acrobat reads the state of selected check boxes and radio buttons.
Reflow text in a PDF. You cannot save, edit, or print a document while it is in Reflow view.

When this check fails, it’s possible that the document contains content that isn’t accessible to people who are color-blind. You cannot save, edit, or print a document while it is in Reflow view. Content cannot be script-dependent unless both content and functionality are accessible to assistive technologies. Disclaimer and Testing Details: Following these techniques will increase the accessibility of your documents, but it does not guarantee accessibility to any specific disability groups.
