” Most, but not all, eBooks have a print version they’re generated from. Typically, our workflow starts with the InDesign file of the print book version, from which we export an epub file. From there, we fine-tune the coding of the epub, generate an embedded table of contents, and then test the file to ensure it’s “valid” for distribution to Apple, B&N, etc.
At this point, we send the client an epub “proof” to load to a device(s) for review. After any necessary revisions and client approval of the epub, we generate a mobi file for review on the Kindle. Upon approval of the mobi, we pass on the final, distribution-ready epub and mobi files.
If the eBook does not have a print version to start with, or the print version is not in Adobe InDesign, we can also work with Word docs and PDF files.”
