How to Review a Print Book Proof Before You Publish

What should you have beside you when the proof arrives?

Keep the approved cover and interior files, your print specifications, and a single correction list within reach. Confirm the binding, finished page size, paper, and ink choice against your order. Record the file names or version numbers for the copy you’re checking. If you ordered proofs from two printers, label each copy as soon as you open the package.

If your paperback and hardcover are both part of the release, review each in its own binding. A paperback proof tells you how the paperback opens and reads. You still need to inspect the hardcover’s cover alignment and inside margins. Give each format its own sign-off.

What should you check on the cover and spine?

Start with the front cover. Compare the title, subtitle, and author name with the approved file. Look at the corners and edges for unexpected white strips or clipped artwork. Then set the book on a shelf at eye level. Check whether the spine text is readable and sits where you expect. Turn the book over and read the back cover copy, including any small print.

Compare the spine against your printer’s template. For KDP paperbacks, spine width depends on page count and paper type. If an interior correction adds or removes pages, recheck the cover dimensions before uploading the revised files.

If your proof uses a test barcode, verify the intended retail barcode area in the final cover file or platform preview. KDP identifies its proofs with a “Not for Resale” mark and a separate barcode without an ISBN.

How should you review the interior?

Turn every page once. Check the title page, copyright page, contents, chapter openings, and back matter. Compare the contents page with the printed page numbers. Look for missing or duplicated pages, unexpected blank pages, and headings stranded at the bottom of a page. Use your approved files to confirm whether a blank page belongs there.

Then read several spreads while holding the book as a reader would. Pay attention to the gutter, the space near the binding. If you have to press the book flat to read a line or see a chart label, flag the page. Look at any artwork intended to reach the edge. Printers call the extra artwork extending beyond the cut line bleed. Use your printer’s specifications when requesting a correction.

Test the pages your reader will use most. For a workbook, write a full answer in one exercise space. For a children’s book, read aloud and check what the next page reveals. For a memoir with family photos, check faces and captions under ordinary room light. For a book with diagrams, check the smallest labels and any distinctions shown through color or shading.

How do you tell a file problem from a printing problem?

Compare the physical copy with the printer’s digital preview and your submitted files. If the same chart label is missing in both the file and the printed book, start with the layout. If the files look correct and the proof has a loose page or damaged cover, photograph the issue and ask the printer to review the copy before changing your files.

A single proof shows how one copy turned out. IngramSpark notes differences between orders, including proof orders, due to production location and equipment. If alignment concerns you, check the printer’s published tolerances and ask whether a design with more space around the spine or trim would address the issue.

What should you fix before you approve the edition?

Keep one correction list. For each issue, record the printed page number or cover location, what you found, the requested change, and who owns the correction. If the printed and PDF page numbers differ, record both. Add a photo when position, color, or binding is the concern.

Here’s a sample note for a workbook: “Printed page 42, PDF page 48. The first column label is difficult to read near the binding. Move the table away from the gutter and recheck the adjacent spread.” Give your designer enough information to locate the issue and verify the change.

My recommendation is to order another physical proof if revisions change the spine, binding, trim, margins, image placement, or several pages of layout. For an isolated typo with no change to line breaks or pagination, check the corrected page and adjacent spread in the printer’s updated preview. Before release, record who approved the edition, which file versions they reviewed, and the date.

What’s your next step?

Write down who will review the proof, which edition they will check, and who will approve the final files. If you’re mapping the rest of your release, see how proof review fits between file preparation and publication.
