The instructions for creating accessible PDFs with Word, PowerPoint and InDesign from the TU Dresden refer, among other things, to the online tool PAVE for checking PDF documents for accessibility.
This is supposed to lead to an accessible PDF in four steps:
A short YouTube video (15’09”) demonstrates the functionality of PAVE 2.0:
The PDF Association has published a new guideline for the technically correct creation of accessible documents. The manual, entitled Tagged PDF Best Practice Guide: Syntax, is intended primarily for developers. It is intended to help developers understand the syntactic properties tagged PDFs need to meet accessibility requirements.
The guide is intended for interested parties who want to prepare accessible PDF documents in detail. On 70 pages, aspects such as PDF/UA as the standard for accessible PDF documents and general regulations are explained. In addition, developers and experienced users are provided with examples of the standard structure types and important information about attributes as well as properties, text features and other properties of PDF.
The new plug-in axaio MadeToTag version 1.9.093 for InDesign CS6 – CC 2018 contains new options for the export tag selection to map the semantic structure in a PDF document even more accurate.
In a correctly tagged PDF, special text elements, such as Caption, Blockquote and Index, must be specifically marked as such. The PDF/UA standard (PDF for Universal Access) also provides the assignment of these specific tags in order to map the semantic structure in the PDF as precisely as possible. However, only basic tags (header or simple text) are used in InDesign. Special elements, such as Caption, Blockquote and Index, did not have their own tag equivalent in InDesign.
Callas software published version 2.0 of callas pdfGoHTML. This free Adobe Acrobat plugin converts tagged PDF files into HTML format. A key feature of this new release is the total redesign of the way that tag structures are visualized. callas pdfGoHTML 2.0 is also significantly more robust when handling PDFs with unusual or very complex tag structures, and it now also fully supports PDF 2.0.
