Why fillable PDF forms & complex tables fail Section 508 QA

  • Untagged widget annotations: Interactive text boxes, checkboxes, and radio buttons lack <Form> structure parents and /OBJR object references.
  • Missing /TU spoken tooltips: Visual labels sit next to boxes on screen, but screen readers announce blank fields without explicit /TU descriptions.
  • Broken keyboard focus order: Pages with links or form inputs omit /Tabs /S, forcing Tab order to jump across visual columns.
  • Complex multi-column tables: Financial and fee tables omit <TH Scope="Column"> / <TH Scope="Row"> or leave stray spans directly inside <TR>.
FAQ

Frequently asked questions

Does your checker detect fillable AcroForm and scanned OCR barriers?
Yes. The checker inspects /AcroForm field dictionaries for missing /TU tooltips, checks /Tabs /S keyboard focus binding, and flags image-only scanned PDFs that lack searchable text operators.
Can you remediate cryptographically signed government PDFs?
Modifying the tag tree of a cryptographically signed PDF invalidates its byte-range signature hash. We either remediate your unsigned source PDF prior to final signing or remove an obsolete signature lock upon authorization so your team can re-sign the compliant PDF/UA file.
How fast can we test a sample file?
Submit any 3–10 page non-confidential PDF via our intake form or email halocrypto101@gmail.com for a complimentary 24-hour remediated sample with 0 failed veraPDF 1.30.3 rules.
