Ability to make PDF/A-1a
PDF/A-1a (accessible) generally requires more effort during the generation process but offers enhanced access to content (especially for text). The structure of PDF/A-1a has the advantage that the reuse of text – for example, by means of an export function – is generally unproblematic, avoiding issues such as misaligned paragraphs and truncated words. PDF/A-1a also brings benefits for search functions. (To avoid any misunderstanding, please note that PDF/A-1b files also provide searchable text.) Lastly, users who want to create accessible PDF documents have – in PDF/A-1a – a format that is optimally suited to their needs.
