Print on demand book printing
Print on demand means your book is printed when a copy is ordered, not in a bulk run held in storage. There is no minimum quantity, no inventory to fund, and no boxes in your spare room.
It is how most self-published paperbacks stay available indefinitely. The trade-off is a higher cost per copy — and whether that trade is worth it depends on how many copies you expect to sell, and how fast.
The short version. Print on demand costs more per book but nothing upfront. Offset printing costs less per book but has a minimum run and you pay for all of it whether it sells or not. Below roughly 500 copies print on demand is usually the right call. Above that, offset gets cheaper per copy and the gap widens quickly.
How print on demand works
- Your interior and cover are prepared as print-ready files — correct trim, bleed, embedded fonts, CMYK colour, and a barcode block if the book carries an ISBN.
- The files are loaded to the printing and distribution system, and your ISBN identifies the edition.
- When a copy is ordered — through a retailer, a distributor, or directly — a copy is printed, bound and shipped.
- You receive the royalty or the sale proceeds for that copy. There is no stock to manage and no reprint to authorise.
Because nothing is held, a title can stay in print indefinitely. A book that sells three copies a month is as viable as one that sells three hundred — which is not true of a bulk run, where unsold copies are a sunk cost.
Print on demand versus offset
| Print on demand | Offset | |
|---|---|---|
| Minimum order | None — one copy at a time | Usually 500 or more |
| Cost per copy | Higher; digital printing, no plates | Lower at volume; plates spread across the run |
| Upfront cost | None beyond file preparation | The full run is paid for before printing |
| Unsold copies | None — nothing is printed until it is ordered | Held as stock; a sunk cost if they do not sell |
| Availability | Indefinite, as long as the files are live | Until the stock runs out |
| Colour fidelity | Good | Highest, particularly for art and photography |
| Best for | New titles, steady modest sales, a backlist | Established demand, launches, events, bulk buyers |
Where the crossover falls. Around 500 copies. Below it, print on demand usually wins once you account for unsold stock. Above it, offset pulls ahead — and at 1,000 copies and beyond the difference is large enough that most authors printing for a known audience should be running offset.
Running both together
This is what most established self-published authors end up doing, and it is worth planning for from the start:
- A bulk offset run for the copies you know you will place — events, reviewers, direct sales, bulk buyers, and stock for retail.
- Print on demand left running for individual orders that arrive afterwards, so the title never goes out of stock.
- Both use the same ISBN for the same edition, so the listing and the retail record stay consistent.
The one thing to check before committing to print on demand only: if you have a launch or an event on a fixed date, order those copies in advance.Demand printing produces a copy within days of an order, which is fast — but it is not stock sitting on a shelf, and it will not absorb a hundred orders in one week.
What print on demand does not remove
Removing inventory does not remove the need to produce the book properly. Before any edition goes live, whether printed on demand or in bulk, the files must be correct:
- Interior and cover at the correct trim size, with bleed where artwork runs to the edge
- Fonts embedded or outlined
- CMYK colour, not RGB — including small decorative elements
- A barcode block on the back cover, pure black on white with a clear quiet zone
- Spine width calculated from the actual page count, paper stock and trim
- An ISBN, since this is a printed edition
A print-on-demand file that fails these checks will be rejected, and the fixes are not cosmetic. This is the work that has to happen before the book can be printed at all, whichever method you choose.
Frequently asked questions
What is print on demand?
Print on demand means your book is printed only when a copy is ordered, rather than in a bulk run held in storage. There is no minimum quantity and no inventory to pay for. It is how most self-published paperbacks stay available indefinitely without the author funding a print run.
Is print on demand more expensive per copy?
Yes, per copy. Digital printing has a higher unit cost than offset, because the setup cost is carried by fewer books. The trade-off is that you avoid paying for stock upfront, you never pay for copies that do not sell, and there is no storage or fulfilment to manage. For a book selling steadily in modest numbers, print on demand is often cheaper overall once unsold stock is counted.
When is offset printing better than print on demand?
From roughly 500 copies upward, and decisively at 1,000 and above. At that volume the plate and setup cost is spread across enough books that the per-copy price falls well below digital. If you expect to sell a large number quickly — through speaking, events, an existing audience or bulk buyers — offset is usually the better route, sometimes with print on demand kept running alongside for individual orders.
Can I run both print on demand and a bulk offset run?
Yes, and it is a common approach. Print a bulk run for the copies you know you can sell or hand out — events, reviewers, direct buyers — and keep print on demand live for individual orders that arrive afterwards. Both use the same ISBN for the same edition.
Do print-on-demand books look different from offset books?
On a well-specified job, not noticeably. The difference shows most on colour interiors and on very high page counts. Digital colour is good but not identical to offset colour, so for a photography or art book where colour fidelity matters, offset is worth considering even at lower quantities.
Does print on demand work for hardcover?
Yes. Hardcover print on demand is available, though the unit cost is higher than paperback and the choice of cover finishes may be narrower than in offset. For a title where hardcover matters, it is worth comparing a short offset hardcover run against print-on-demand pricing before deciding.
What about the interior colour in print on demand?
Both black-and-white and colour interiors are available. Black-and-white is the economical choice and what most books use. Colour print on demand costs noticeably more per page, so it suits picture books, cookbooks and art titles where colour is the point of the book.
How quickly are print-on-demand orders produced?
Typically within a few working days of the order, plus shipping. That is faster than an offset run, which needs plate making and press scheduling, but slower than having stock already printed and sitting on a shelf. If you have a time-critical launch or event, it is worth printing a small batch in advance rather than relying on demand printing for those copies.
Do I need an ISBN for print on demand?
Yes. A printed edition needs an ISBN, because bookshops, libraries and distributors identify print editions by ISBN. If you are publishing only a Kindle eBook, an ASIN is sufficient and no ISBN is required — but the moment a physical book exists, it needs one.
