Before and after comparison of the delivered work
THE CLIENT

An International Publishing Enterprise

The client is a multinational publishing organization with an established presence across the United States, the United Kingdom, and Europe. Its publishing portfolio spans four divisions: academic publishing, educational resources, children’s literature, and trade publishing. Its catalog includes scholarly and professional publications, textbooks and digital learning resources, illustrated children’s books and young adult titles, and mainstream fiction, non-fiction, and specialist-interest publications.

PROJECT REQUIREMENTS

Scalable ePub3 Conversion (With WCAG AA Compliance)

The client required a team to convert 75,000–100,000 pages each month across their four publishing divisions. The resulting files had to meet international ePub3 accessibility guidelines while preserving the distinct layouts, design elements, and reading experience associated with each content category. Beyond file conversion, the client required dependable performance across e-readers, tablets, mobile devices, and assistive technologies. They engaged ePub3 conversion services from Data-Entry-India with accessibility compliance support to combine large-scale processing with consistent rendering, accessible navigation, and preservation of each publication’s design integrity.

STM manuscripts

packed with equations, chemistry notation, and tabular data that demanded technically fluent composition.

Academic volumes

built on strict citation structures, multi-level footnotes, and formal layout hierarchies.

Educational content

published in multiple languages, each carrying its own typographic rules and script considerations.

Trade titles

where creative page design and reading comfort carried commercial weight.

Illustrated books

in which the balance between artwork and text defined the reading experience.

PROJECT CHALLENGES

Managing High-Volume, Accessible ePub3 Conversion across Diverse Formats

The project left little room for inconsistency. Errors introduced during ePub3 conversion could affect accessibility, downstream QA, and publication readiness across thousands of files, making quality control critical throughout the conversion lifecycle.

Large-Scale Production

Delivering 75,000–100,000 pages per month required a production model that could handle substantial throughput without compromising quality standards or international publishing deadlines.

Format-Specific Conversion Needs

The client’s catalog included multimedia-based learning content, formula-intensive academic titles, heavily illustrated children’s publications, and reflowable trade books. These variations made a uniform conversion method impractical and required specialized processing for each content type.

Device and Platform Compatibility

Converted ePub3 files had to perform reliably across Apple Books, Google Play Books, Kindle, tablets, smartphones, and assistive technologies. Maintaining consistent navigation, rendering, and usability across these environments added another layer of complexity.

Continuously Changing Compliance Requirements

Our accessibility-first ePub3 conversion workflow had to accommodate evolving international ePub3 accessibility guidelines while also supporting multilingual content distributed across global markets.

OUR SOLUTION

ePub3 Conversion Services for Accessible Publishing at Scale

We established a structured ePub3 conversion workflow to manage the client’s varied content portfolio at enterprise scale. The production model combined format-specific conversion, embedded accessibility, multi-stage validation, and flexible resource allocation while maintaining consistent standards across all four publishing divisions.

1

Accessible Semantic Architecture

We structured each publication with HTML5 semantics to create a consistent reading hierarchy and improve compatibility with assistive technologies. Navigation landmarks enabled screen readers to interpret chapters, sections, tables, and supporting elements more effectively. Structured heading levels created a predictable reading sequence, while multimedia-rich titles included captions, synchronized audio-video support, and accessibility information for interactive content.

2

Content-Specific ePub3 Production

Each publishing category required a conversion method suited to its presentation and reading requirements. We used reflowable ePub3 layouts used for academic and text-intensive publications. Fixed-layout formats preserved illustrations and page composition in children’s titles. Educational resources with interactive elements were developed using media-rich ePub3 capabilities. We tested completed files across Apple Books, Kindle, Google Play Books, Adobe Digital Editions, and browser-based readers to confirm consistent behavior across major reading environments.

3

Accessibility Compliance across the Catalog

To support the client’s global publishing requirements, we configured non-Latin characters, right-to-left scripts, and multilingual metadata for accurate global distribution. Font scaling, responsive layouts, and reflowable content supported varied screen sizes and reader preferences, while alt text, suitable contrast, and accessible color treatment improved usability for readers with visual disabilities. We also validated each title against WCAG 2.2 Level AA, EPUB Accessibility 1.1, and relevant international ePub3 accessibility guidelines.

4

Automation with Human-in-the-Loop QA

We combined automated validation with specialist review to identify both technical errors and accessibility issues that required human judgment. Automated checks used tools including FlightCrew, Pagina ePub Checker, and EPUB Validator. We also validated package structure, manifests, metadata, schema integrity, and asset linking. Accessibility and design specialists then reviewed alt text, navigation behavior, tables, visual presentation, and interactive elements before final delivery.

5

Flexible Resource Allotment

A team of 40 to 50 dedicated ePub3 specialists supported the client’s regular production volume of 75,000–100,000 pages each month. The specialists were trained on the client’s content structures, quality requirements, and accessibility expectations. During peak publishing cycles, we allocated additional resources to absorb volume increases while maintaining delivery schedules. Our model ensured consistent quality, timely delivery, and predictable turnaround across regular and high-volume cycles.

PROJECT OUTCOMES

  • Processed 75,000–100,000 Pages Each Month

    We ensured consistent high-volume delivery across all four publishing divisions without disrupting scheduled release timelines.

    Final ePub3 files met WCAG 2.2 Level AA, EPUB Accessibility 1.1, and relevant ePub3 accessibility guidelines for accessible digital publishing.

  • Achieved 95%+ First-pass Acceptance Rate

    Structured conversion and multi-stage quality checks reduced rework, helping the client accelerate review and publication cycles.
