This international publishing conglomerate is well-established across the United States, the United Kingdom, and Europe. Their extensive catalog encompasses four core divisions – academic publishing (scholarly research, professional reference materials), educational resources (textbooks, interactive learning platforms), children's literature (illustrated picture books, young adult fiction), and trade publishing (mainstream fiction, non-fiction, specialty interest titles).
The client required ePub3 conversion with international accessibility standards compliance of 75,000 to 100,000 pages per month across their four publishing divisions. Beyond format conversion, they required outputs with seamless functionality across e-readers, tablets, mobile devices, and assistive technologies, while preserving the unique design integrity of each content type.
Processing 75,000 to 100,000 pages monthly while maintaining strict quality standards and meeting aggressive publication deadlines across multiple international markets.
Handling diverse formats including multimedia-rich educational materials, complex academic publications with mathematical formulas, intricately illustrated children's books, and reflowable trade titles—each requiring specialized conversion approaches.
Ensuring proper functionality across major e-reading platforms (Apple Books, Google Play Books, Kindle) and maintaining optimal user experience on tablets, smartphones, and assistive technologies.
Adapting to frequent updates in international ePub3 accessibility guidelines while supporting multilingual content across diverse global markets.
We engineered a specialized production ecosystem that transformed the inherent challenges of enterprise-scale ePub3 conversion into streamlined, quality-driven outcomes. Our approach addressed the unique requirements of each content division while maintaining unified standards across the client's entire catalog.
We applied HTML5-based structuring to provide every file with a logical reading order and ensure that each title is machine-readable, accessible, and consistent across formats.
Different types of content demanded different treatments. Academic titles were produced in reflowable layouts for flexible reading. Illustrated and children’s books were developed in fixed layouts to preserve design integrity. Educational resources with interactive features were built into media-rich ePub3 formats. Every output was tested for performance across major platforms, including Apple Books, Google Play Books, Kindle, Adobe Digital Editions, and browser-based applications.
Our accessibility-first ePub3 conversion approach - embedding accessibility features directly into every ePub3 file – ensured usability across diverse reader groups and assistive technologies. This included:
A multi-layered QA framework (using automation for data and design validation, followed by specialist review to catch any errors that the automated tool missed) was implemented to manage outcome quality:
To manage volumes of 75,000–100,000 pages per month, we assigned a dedicated pool of 30–40 ePub3 specialists and also trained them to handle the client’s particular content types. During peak publishing cycles, we scaled resources seamlessly to absorb surges without affecting delivery timelines. This flexible model ensured:
Consistent throughput across academic, educational, children’s literature, and trade categories.
Validated against WCAG 2.2 AA, EPUB Accessibility 1.1, and other regional compliances.
Reduced rework and sped up release cycles for the client.
We’ve worked with SunTec for years now, and what we value most is their dependability. They’ve scaled with us and sped up our release cycles, without ever compromising on quality.
