Ipedis supports its customers since 2006 in their e-accessibility initiatives (Consulting, design and development of websites and mobile applications, publishing, video, training). Ipedis is a pioneer in PDF accessibility and the main stakeholder on the market. With thousands of pages processed every year, Ipedis has acquired recognised know-how and expertise.
Adobe, the creator of the PDF format, has for many years offered the manual insertion and association of XML tags in content which help to make this format accessible. Ipedis has developped his own tagging method in accordance with: PDF/UA standards (recognized ISO 14289-1:2012). This method is certified e-accessibility.
You can send us either the InDesign sources (with fonts and assets) or the final PDF, and we will make the tagging of the document in accordance with PDF/UA standard.
We provide you a General Guide for DTP good practices with the list of files required for treatment.
The PDF format is an image by default; therefore, assistive technologies cannot transcribe the information contained in this type of file if alternative text is not provided. Moreover, the amount of text and the presence of various editorial elements do not make it possible to provide an alternative compliant with the communicated information. For a PDF to be accessible, it must be tagged and must respect the reading order.
Tagging is an invisible XML layer of code automatically generated when good practices are applied. Assistive technologies interpret this code and communicate the information to the user.
What we do for example:
- information about the order in which the text should be read
- information for the alternate text of visuals and photos
- tagging of tables (titles of columns, reading direction)
- the creation of alternatives for tables and/or complex diagrams
- le balisage et la lisibilité des folios
- tagging of language changes which may occur in the document
- information about the document’s properties (document’s language, author, etc.)
- the page display in “page only” mode
Making a PDF accessible involves creative work and requires an in-depth analysis of the document by our experts:
- To determine the most suitable interpretation to describe a background visual which conveys information
- To structure the reading order of a page in order to vocally reproduce intuitive reading by an ordinary person.
