Solutions to preflight, correct and repurpose PDF files for

Verify compliance with PDF/UA.
PDF/UA validation always requires
machine check and semantic checks.

Note!
Important to always consider for conformance validation
against the ISO Standard PDF/UA:

PDF/UA conformance requires validation of
both syntax and semantic.

The Matterhorn Protocol specifies a common set of
31 "Checkpoints" with 136 failure conditions, whereof

• 89 failure conditions can be checked by software, and


• 47 failure conditions usually require human judgment.
