ACCESSIBLE PDFs: How to Make Math Formulas Accessible to Screen Readers

Four Adobe PDF Icons in a row

NOTE: Have been receiving lots of questions concerning the accessibility of math and scientific formulas in PDF documents. This post is the first in a series of how to make STEM content accessible in different document content.

===

Sometimes just complying with basic standards is not enough if you want your PDF document content to be accessible to all assistive technologies.

Case in point: consider STEM (Science, Technology, Engineering, and Mathematics) formulas.

According to PDF/UA accessibility guidelines, “All mathematical expressions shall be enclosed within a Formula tag and shall have an ALT attribute.”

How to Describe an Equation

Have a look at this math equation:

m equals begin fraction m sub 0 over begin square root 1 minus begin fraction v sup 2 over c sup 2 end fraction end square root end fraction

You have to remember that the screen reader user is listening to the equation, so its ALT text description would be set to:

ALT=”m equals begin fraction m sub 0 over begin square root 1 minus begin fraction v sup 2 over c sup 2 end fraction end square root end fraction” [SOURCE]

Advice from Adobe

“Because speech software may handle Formula tags differently from normal text, it may be necessary to add a description using alternate text.”

However…

…according to Ted Page of Accessible Digital Documents, if you do so, the content may not be read by some earlier versions of the NVDA screen reader, with or without an ALT attribute.

Solutions That You Should Test

  1. Nest a <P> tag in the Formula tag that has a text alternative in an Actual Text attribute. This content can be accessed by NVDA.

  2. The Formula tag is an inline level element. If it is used as a block level element, the attribute “Placement: Block” is required. Otherwise some assistive technologies are not able to present it correctly. Follow these steps:

    1. In the Acrobat Pro Tags pane, right click the Formula tag.
    2. Select Properties.
    3. On the Tag tab of the Object Properties dialog, click the Edit Attribute Objects button.
    4. In the Attributes dialog, if there is not a “/Attribute Object # <<Dictionary>>” item, click the New Item button.
    5. Select “/Attribute Object # <<Dictionary>>” and click the New Item button.
    6. In the Add Key and Value dialog, enter Placement in the Key field, and Block in the Value field. Leave Name as the Value Type.
    7. Click OK.

ACCESSIBLE PDFs: How to Correct Typos in Tagged Text

Four Adobe PDF Icons in a row

What happens when your tagged text doesn’t match visual text?

Even though the text in your PDF looks correct, there may be typos or extra spacing behind the scenes that causes screen readers to announce the content incorrectly.

Tagged text must be free from line breaks and split words. The Adobe Accessibility Checker does not alert you to these issues.

Here’s how you can determine the back-end content issues and fix them, using Adobe Acrobat Pro DC.


How to Figure Out What is Wrong with the Content

1) Open the PDF in Adobe Acrobat Pro DC.

2) Select File > Save as > Text (Plain).

3) Save the file to your computer.

4) Open the text file in Microsoft Word.

5) Use the grammar and spell check tools to find typos or spacing issues.


How to Fix These Problems in the PDF File

1) With the PDF open in Adobe Acrobat Pro DC, select the Tags Tree

2) Locate the tag containing the typo or spacing issue.

3) Right click and select Copy Contents to Clipboard

4) Right click the tag again and select Properties

ACCESSIBLE PDFs: How to Set the Document Root

Human hands holding a young green plant

Every PDF document needs a “root.”

I get this question all the time from fellow PDF remediators:

“I am getting this error: ‘”Part” structure element used as root element.’ How can I fix it?”

You need to set the root of the PDF as “Document.”

HERE’S THE FIX

1) In the Acrobat Pro DC Tags pane, create a new Document tag and position it at the root under the Tags tree.

2) Select the rest of the tag structure and drag it inside (under) the root Document tag.

3) Save the file.

Five PDF icons in a row

If you have a PDF document that has 21 or more pages, you need to include bookmarks that parallel the accessible document structure. This allows folks who use assistive technology an easier way to navigate a PDF document.

NOTE: Bookmarks are best added after the document structure tags are finalized.

How to add bookmarks based on a document’s structure via Adobe Acrobat Pro DC:

1. Select Bookmarks icon on the Accessibility Checker panel
2. Select the Options icon
3. Select New Bookmarks from Structure

Adobe Acrobat Bookmark Menu
4. In the Structure Elements dialog box, select the element(s) that you want to use as bookmarks.

ACCESSIBLE PDFs: How to Embed Missing Fonts

Five PDF icons in a row

I have written about the importance of adding a PDF/UA identifier to your PDF files to help with accessibility.

The PDF/UA flag in the document informs screen readers and AT software that the PDF’s structure elements are logically ordered and semantically correct. This enables the AT apps on different devices (desktop, mobile, tablets) to process correctly-tagged PDF content consistently for a multitude of users.

Let’s talk about why you should embed missing fonts

Embedding missing fonts ensures reliable presentation of the PDF document’s text because the AT viewer is not forced to substitute fonts that may not match the usage specified in the document.

Fonts that are embedded can also help speed up the editing process. Let’s say you discover a typo and need to fix it via Adobe Acrobat Pro DC. You should be able to fix the text in the document using the original font.

How to embed missing fonts

1. Open the PDF document in Adobe Acrobat Pro DC.
2. Go to Print Production > Preflight.
3. Make sure the Adobe Acrobat Pro DC 2015 Profiles is selected.
4. Select PDF fixups.

ACCESSIBLE PDFs: How to Prevent Security Settings from Interfering with Screen Readers

Five PDF icons in a row

When creating a PDF file using Adobe Acrobat DC Pro, a document author can specify that no part of an accessible PDF is to be copied, printed, extracted, commented on, or edited.

Problem is this security setting can interfere with a screen reader’s ability to read the document, because screen readers must be able to copy or extract the document’s text to convert it to speech.

How to fix accessibility permissions manually

1. Open the PDF in Adobe Acrobat DC Pro
2. Choose File > Properties > Security.
3. Choose No Security from the Security Method drop-down list.
4. Click OK and close the Document Properties dialog box.

Is your screen reader a Trusted Agent?

From Adobe: “If your assistive technology product is registered with Adobe as a Trusted Agent, you can read PDFs that might be inaccessible to another assistive technology product. Acrobat recognizes when a screen reader or other product is a Trusted Agent and overrides security settings that would typically limit access to the content for accessibility purposes. However, the security settings remain in effect for all other purposes, such as to prevent printing, copying, extracting, commenting, or editing text.”
