Who should review the layout file before it is sent to print?
In short: Four reviews, four people responsible. The proofreader does the last read over the laid-out pages; the designer does the layout review (widows, orphans, alignment, styles) and the technical one (PDF preflight); the editor or author does the final content check and approves; the printer verifies the file and issues the proof, which the designer and whoever publishes check before releasing. Skipping any of these stages is the origin of almost every printed error.
The book reaches the printer with a typo on the first page, a heading alone at the bottom of another and a low-resolution image on the cover. Each of these faults belongs to a different review — and each was skipped because someone assumed another person had looked. The question "who reviews?" has a four-part answer, and the process is only safe when all four happen, in the right order, with named people responsible.
1. The four reviews and who is responsible
Text review over the laid-out pages — the proofreader
The main text review happens before the layout, on the text file. But the layout introduces new problems — incorrect hyphenations, words that split awkwardly at the end of a line, notes that moved to another page, an outdated table of contents — and that is why there is a last read over the laid-out PDF. Whoever does it is the proofreader (or the copy preparer), not the author: the author has read their own text so many times that they no longer see the errors.
What that read looks for: remaining typos, hyphenation, agreement between the table of contents and the pages, numbering of notes, chapters and figures, correct captions, cataloguing record and credits.

Layout review — the designer
The designer reviews their own work with a specific eye, different from the creative one. It is a page-by-page pass, preferably printed, looking for:
- Widows and orphans (isolated lines at the start or bottom of a page)
- Headings separated from the text they introduce
- Rivers and irregular spacing in justified paragraphs
- Line alignment between facing pages (vertical rhythm)
- Elements outside the styles — manual formatting that will be lost
- Consistency of chapter openings, running heads, folios and notes
- Bleed and the position of images that touch the edge

Technical review (preflight) — the designer
Unlike the previous one, this does not look at the page; it looks at the file. It is the check that the PDF meets the printer's or platform's specifications: page size and bleed, embedded fonts, image resolution, colour profile, ink coverage, PDF type, crop marks, cover spine calculated with the final page count. Layout software and Acrobat have preflight tools that automate part of this; the rest is a manual check against the specification. On this process, see How are files prepared for the commercial printing of a book?
Final check and approval — the editor (or the author)
Whoever publishes does the last content check — not of the text, which has already been proofread, but of integrity: all the chapters are there, in the right order; the credits, the dedication, the epigraph and the cataloguing record are correct; the ISBN and barcode match; the cover has the exact title and name; the back cover has the approved text. And gives approval in writing: "released for printing". Without that recorded approval, the designer should not send the file.
Why the author does not replace the proofreader
It is not a question of competence — it is of familiarity. Whoever wrote the text reads what they meant to write, not what is written. The professional proofreader reads what is on the page. Authors who review their own book let through errors an ordinary reader spots on the first page.
2. The printer reviews too — but not what you imagine
The printer (or the print-on-demand platform) checks the file against its own specifications: size, bleed, fonts, resolution, colour. It flags what would stop the print coming out well. It does not review text, does not fix widows, does not assess readability and does not know the book. A file "approved by the printer" is a printable file, not a reviewed book.
In offset, the printer issues the proof — the printed version or certified PDF of what will be produced. It is the last chance to see the book before the run. Who checks the proof: the designer (colour, trim, spine, alignment) and whoever publishes (content integrity). The proof approved in writing releases the printing. On what the printer requires and where to check it, see Where to check the technical print specifications required by each distributor or printer?
In print on demand, the equivalent of the proof is the proof copy — a single book printed before publishing. It is always worth requesting. It is there that you discover the cover's navy came out grey, the spine shifted two millimetres or the inner margin is tight.
3. The order matters
The reviews overlap if done in the wrong order. The sequence that works:
- Text reviewed and finalised (proofreader) → enters the layout
- Layout completed → layout review (designer)
- Reading PDF → last read over the pages (proofreader) → targeted corrections by the designer
- Corrected file → technical review / preflight (designer)
- Final PDF → integrity check and written approval (editor or author)
- Sent to the printer → printer's check → proof
- Proof checked by designer and whoever publishes → release in writing
The most common mistake is stage 3 generating large text changes — rewritten paragraphs, reordered chapters — that redo the pagination and force stages 2 to 5 to be repeated. That is why the text needs to be finalised before entering the layout; the last read is for targeted errors, not editing. On what "finalised" means, see What does the designer need to receive from the author or publisher to start a layout project?
One person per stage, in writing
Before starting, the project defines who does each review and by when. When the proofreader and the designer are the same person, or when the author also takes on the editor's role, the stage still exists — only who executes it changes. What cannot happen is a stage with no owner.
4. In self-publishing
The independent author usually also takes on the editor and, sometimes, the proofreader. The risks and the ways out:
- Text review: hire a proofreader, even if for a single pass over the laid-out PDF. It is the book's best-return investment.
- Layout and technical review: these belong to the designer; if the author laid out the book themselves, they need to do both with the checklist in hand — and request the proof copy.
- Integrity check: the author does it, with a written list, after a few days without looking at the file.
- Proof: always. A printed copy costs little relative to what it prevents.

5. What each review catches — and what it lets through
| Error | Who catches it | Who doesn't |
|---|---|---|
| Typo | Proofreader (last read) | Designer, printer |
| Heading alone at the bottom of the page | Designer (layout review) | Proofreader, printer |
| Low-resolution image | Designer (preflight), printer | Proofreader, editor |
| Missing chapter | Editor/author (integrity) | Printer |
| Wrong spine | Designer (preflight), printer, proof | Proofreader |
| Colour different from expected | Proof | All the above |
| Table of contents with wrong pages | Proofreader (last read), editor | Printer |
Every line of this table is an error that has already come out printed in some book because the right person did not look. On how to resolve it when the printer flags a problem too late, see When the layout clashes with the printer's technical requirements, what should you do?
Frequently asked questions
Is the designer responsible for reviewing the book's text?
No. The designer reviews the layout (widows, orphans, alignment, styles) and the technical file (preflight). The text review belongs to the proofreader, who should do a last read over the laid-out PDF.
Can the author do the final review?
The author does the integrity check (chapters, order, credits, cataloguing record, cover) and approves. The text review should be by someone else, because whoever wrote it does not see their own errors.
Does the printer review the book?
The printer checks whether the file is printable — size, bleed, fonts, resolution, colour. It does not review text or layout. A file approved by the printer can contain content errors.
Do I need to request a printed proof?
Yes. In offset, the proof is part of the process and should be checked by the designer and whoever publishes before release. In print on demand, the proof copy is the only way to see the real colour, spine and margins before publishing.
What to do if the last read requests large text changes?
Assess whether they are indispensable. Changes that alter the pagination force the layout review and preflight to be repeated. If they are necessary, redo the cycle; if they are preferences, leave them for the next edition.
