PAC 3 released by Access for All

Access for All released PAC 3, the latest version of the free PDF Accessibility Checker, in December 2017. Access for All reports the following improvements:

  • Overview report can be exported as a barrier-free PDF.
  • Optimized accessibility of the user interface.
  • PAC is now available in English and German. More specifically, the language automatically depends on the language set in the operating system of your computer. If this is neither German nor English, PAC will be executed in the English version.
  • New “Artifacts” tab in the Logical Structure dialog box for quick viewing and review of all decorative items.
  • Additional attributes on the Properties tab in the Logical Structure dialog such as PrintField attributes, IsMap attribute, and ListNumbering attribute.
  • Another checkpoint in the category Logical structure”> “Structure elements”> Tables: Assignment of header cells”.

After using PAC 3 in parallel with PAC 2 for a few weeks, as far as I have been able to tell the test functionality is identical – with the exception of the new check for assignment of header cells. PAC 3 has an improved user interface, in my opinion, and unlike PAC 2 is itself fully accessible to assistive technology users.

The ability to produce a summary test report in accessible PDF format is a very welcome new feature. The Screen Reader Preview seems slightly improved, with images displayed smaller than in PAC 2. PAC 3 also seems more stable than PAC 2 – I tested a couple of files that crashed PAC 2 but not PAC 3. I have only detected one minor glitch in PAC 3 – the metrics (e.g. number of failed Content checkpoints) in the summary report are exactly double those in PAC 2 and in the PAC 3 detailed report.

In conclusion, PAC 3 is a welcome addition to my PDF accessibility toolbox. PAC 3 – and also the older PAC 1.3 and PAC 2 – can be downloaded from Access for All (http://www.access-for-all.ch/en/pdf-lab/pdf-accessibility-checker-pac.html).
