Session 2 – The Basics of PDF Accessibility

Slide9

Source Document

The Source Document is SupremeThings to consider when creating the source document:

Does the authoring tool of the source document allow the author to create an accessible document.

For Example: Word has an Accessibility Checker to help the author make the document more accessible.

Does the author know how to create an accessible documentFor Example: In Word, are Styles used to apply Headings or are headings “created” by changing the font size and making the font bold?

REMEMBER: It is almost always easier to remediate the source document then the converted PDF document.

Slide10

Let’s Talk About PDF/UA

ISO 14289-1 (in process of revising) is a subset of and references ISO 32000Electronic document file format enhancement for accessibility

Designed to identify the semantic information necessary for assistive technologies to access the information in the document such as text, structure, and organization of the content.

Shall vs. May

e.g., lists – Individual list items shall be specified by <LI> tags. <Lbl> and <LBody> tags may be included.

Organizations define their own specific rules

e.g., HHS requires <Lbl> and <LBody> tags for compliance

Conventions

<Document> tag should be the first tag in the tree structure (not required by PDF/UA)

Artifact images with captions (no alternative text - AltText)

Slide11

Hierarchy of Tasks

(Here There Be Monsters)

Is the PDF created from a scanned image?

If yes – perform text recognition

Is the PDF a form with fillable form fields?If yes – add the form fields

Does the PDF document or form contain links?

If yes – add the links

Does the PDF have multimedia?

If yes – add the multimedia (make sure it is accessible with captions and video descriptions)

Now

– tag the document

After or during tagging have you edited the documentIf yes, at the very least you will need to remove all tags and re-tag the document or form, it may be necessary to remove all tags, multimedia, links, and form fields and return to step 211

Slide12

Converting to a PDF from a Source Document

Multiple MethodsAcrobat Plug-in

Application Save As

Select “Show Reading Order Panel” (TURO)

Select item number for content to be

artifacted

Select “Background” from TURO

Return to the tag tree and note that the previous empty <P> tag is now gone. (again, this step is unnecessary and only for

illustratation)22
