Arbortext’s EPUB output conforms to the EPUB Standard Version 2. Different e-reader applications have varying levels of support for this standard and you may see differences between output viewed in Calibre e-reader during publishing and your selected reader. Ensure that you have tested output in your various required readers to confirm the appearance is satisfactory. If there are unexpected anomalies, use the View EPUB option in the Publish to EPUB dialog box to confirm the appearance is correct in the Calibre e-reader.
