Session 2 – The Basics of PDF Accessibility © 2017 Adobe Systems Incorporated. All Rights Reserved. Adobe Confidential. 8
Source Document The Source Document is Supreme Things to consider when creating the source document: Does the authoring tool of the source document allow the author to create an accessible document. 1. § 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 document 2. § For 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. © 2017 Adobe Systems Incorporated. All Rights Reserved. Adobe Confidential. 9
Let’s Talk About PDF/UA ISO 14289 -1 (in process of revising) is a subset of and references ISO 32000 § Electronic 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 - Alt. Text) © 2017 Adobe Systems Incorporated. All Rights Reserved. Adobe Confidential. 10
Hierarchy of Tasks (Here There Be Monsters) Is the PDF created from a scanned image? 1. § If yes – perform text recognition Is the PDF a form with fillable form fields? 2. § If yes – add the form fields Does the PDF document or form contain links? 3. § If yes – add the links Does the PDF have multimedia? 4. § If yes – add the multimedia (make sure it is accessible with captions and video descriptions) 5. Now – tag the document 6. After or during tagging have you edited the document § If 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 2 © 2017 Adobe Systems Incorporated.

Converting to a PDF from a Source Document Multiple Methods 1. Acrobat Plug-in 2. Application Save As 3. Export 4. Print to PDF 5. Other conversion tools or plug-ins Varying Results 1. Tables and Lists may be inaccurately tagged 2. Resulting PDF may be untagged 3. Custom tags may be created © 2017 Adobe Systems Incorporated. All Rights Reserved. Adobe Confidential. 12
