Ensure your digital publications satisfy modern distribution requirements and accessibility guidelines. DinoEPUB audits EPUB3 packages with official W3C EPUBCheck and ACE by DAISY tools, identifying structural anomalies, missing language tags, and remediation requirements.
DinoEPUB by TechDino provides EPUB accessibility testing, validation, and structural remediation services for publishers, university presses, and authors worldwide. We evaluate digital publications using official W3C EPUBCheck and ACE by DAISY automated tools, auditing heading order, language attributes, table accessibility, and navigation landmarks. Manual accessibility remediation is scoped through customized quotation.
Standards & Remediation
We audit structural markup to assist publishers in preparing accessible digital books, identifying code deficiencies before marketplace submission.
th scope="col") and landmark references.Digital accessibility requires both syntactic well-formedness and human judgment. We clearly delineate what automated tools evaluate and where expert editorial review is necessary:
Accessibility remediation is scoped on a title-by-title basis depending on current file conditions, image volume, and equation density.

Guidance on EPUBCheck, ACE by DAISY, and accessibility compliance boundaries.
EPUBCheck evaluates technical XML well-formedness, file manifests, and standard EPUB3 package specifications. ACE by DAISY audits accessibility-specific rules such as heading levels, language identifiers, table markup, and alt attribute presence.
No. Automated tools such as ACE by DAISY identify structural and machine-testable items, but cannot determine whether image alt text is contextually meaningful or if complex diagrams are adequately explained. Full compliance requires human review.
Automated syntax and ACE scans are included in our standard conversion proposals. Comprehensive manual accessibility remediation, such as alt-text authoring or MathML conversion, is provided through customized quotation based on document complexity.
We audit semantic heading hierarchies (h1 through h6), page break landmarks, primary and foreign language tags, table header cell scope attributes, reading order, and navigation document landmark links.
We help publishers structure their EPUB3 files with valid metadata, logical reading orders, skip navigation landmarks, and conformant markup, reducing the remediation burden required for European digital market compliance.
