Once the interior and cover are uploaded, order a proof using the platform’s current process. Compare the printed copy with your approved files, paying attention to trim, margins, binding, cover colors and image clarity. Check several pages throughout the book, not only the opening.
Record corrections in one list and verify them in the revised proof or preview. Treat a proof as a production checkpoint, not a formality. The short review can prevent a visible typo or layout problem from reaching readers and early reviewers.
