One Master Cover File for Ebook, Paperback, and Hardcover: A Practical Workflow

If you're publishing the same book as an ebook, paperback, and hardcover, you don't need three separate cover designs — you need one piece of front-cover artwork and three different technical wrappers around it. The mistake most authors make is building each format's file from scratch, which triples the design work and guarantees the three covers drift apart visually. The fix is a layered master file: one locked front-cover layer, plus swappable spine/back/wrap layers per format, assembled in a specific order so you don't undo work you already finished.
