An additional requirement for accessible documents is identifying nontext content, such as graphics and images, in context and describing what is shown.
InDesign offers a direct and simple workflow that dramatically reduces the time and effort required to produce accessible PDF documents from an InDesign layout. Most of the tasks are executed within InDesign, with only a few final steps required in Adobe Acrobat. This allows hierarchical and structural information to reside in the InDesign file, making updates faster and easier when you need to generate a revised accessible PDF document.
To create an accessible PDF, you need the following:
At a high level, the process of creating accessible PDFs consists of a few basic stages:
