EPUB Navigation and Layout Repair | Service Process

Nexvale LLC service process. Julian Vale coordinates requirements, review points and handover through our five-person in-house team. An EPUB repair begins with the reader's problem: a chapter that does not open, a broken internal link, an image that exceeds the reading area, or a navigation entry that points to the wrong place. We inspect the file and agree on a bounded defect list. The original is preserved, and changes are limited to the approved repair. Reading text stays fixed unless editing is separately agreed. After the repair, we check the saved EPUB structure, reading order, navigation, links, and image references. We compare the ordered reading text and review the file at more than one text size. The handover explains the changes and the checks completed. Reader-specific behavior is assessed against the agreed target. Retailer approval is determined by the retailer.
