USING ACROBAT X PRO 284 Accessibility, tags, and reflow To produce the most accessible PDFs from web pages you create, first establish a logical reading order in their HTML code. For best results, employ the Web Content Accessibility Guidelines that are published by the World Wide Web Consortium (W3C). For more information, see the guidelines on the W3C website. 1 Do one of the following: • In Acrobat, choose File > Create > PDF From Web Page, enter the web page address, and then click Settings. • In Microsoft Internet Explorer, in the Adobe PDF toolbar, click the down arrow on the Convert button and choose Preferences. 2 In the General tab, select Create PDF Tags, and then click OK. 3 Specify any other options as appropriate, and then click Create. Creating a tagged PDF from an authoring application In most cases, you create tagged PDFs from within an authoring application, such as Adobe FrameMaker®, Adobe InDesign, or Microsoft Word. Creating tags in the authoring application generally provides better results than adding tags in Acrobat. PDFMaker provides conversion settings that let you create tagged PDFs in Microsoft Excel, PowerPoint, and Word. For more information about creating accessible PDFs, see www.adobe.com/accessibility. For more information, see the documentation for your authoring application. About tags in combined PDFs You can combine multiple files from different applications in one operation to create a single PDF. For example, you can combine word-processing files with slide presentations, spreadsheets, and web pages. Choose File > Create > Combine Files Into A Single PDF. During conversion, Acrobat opens each authoring application, creates a tagged PDF, and assembles these PDFs into a single tagged PDF. The conversion process doesn't always correctly interpret the document structure for the combined PDF, because the files being assembled often use different formats. Use Acrobat Pro to create an accessible PDF from multiple documents. When you combine multiple PDFs into one tagged PDF, it is a good idea to retag the combined document. Combining tagged and untagged PDFs results in a partially tagged PDF that isn't accessible to people with disabilities. Some users, such as those using screen readers, will be unaware of the pages that don't have tags. If you start with a mix of tagged and untagged PDFs, tag the untagged files before proceeding. If the PDFs are all untagged, add tags to the combined PDF after you finish inserting, replacing, and deleting pages. When you insert, replace, or delete pages, Acrobat accepts existing tags into the tag tree of the consolidated PDF in the following manner: • When you insert pages into a PDF, Acrobat adds the tags (if any) for the new pages to the end of the tag tree. This order occurs even if you insert the new pages at the beginning or the middle of the document. • When you replace pages in a PDF, Acrobat adds the tags (if any) from the incoming pages to the end of the tag tree. This order occurs even if you replace pages at the beginning or the middle of the document. Acrobat retains the tags (if any) for the replaced pages. • When you delete pages from a PDF, Acrobat retains the tags (if any) of the deleted pages. Last updated 10/11/2011
