Print on demand or a print run?
There are two ways to turn a finished file into physical books, and they are not competing versions of the same thing. They have opposite risk profiles, and the right one is decided by how your copies reach readers.
Print on demand
A copy is manufactured when someone orders it. The order reaches the printer, a digital press runs the interior, the cover is laminated and trimmed, the book is bound and shipped, usually within a few days. You hold no stock at all.
- No up-front cost. You upload files and list the book. Nothing is spent until something sells.
- No inventory, no warehouse, no fulfillment. The printer prints, packs and ships. You are not taping boxes.
- No unsold copies. The most common way a self-published author loses real money is buying stock they cannot sell. Print on demand removes that failure mode entirely.
- A higher cost per copy. Every copy costs about the same as every other, and that figure is higher than a run would be. You are paying for the flexibility.
- Instant distribution. One file feeds retail listings worldwide without you shipping anything across a border.
This is why virtually every self-published book starts here, and why most of them never need to leave. The four printers we build files for — Amazon KDP, IngramSpark, Lulu and B&N Press — all work this way. Where to print compares them.
A print run
Offset printing is a different manufacturing process. Plates are made, a large quantity is printed at once, and the setup cost is spread across the whole run. Beyond a few hundred copies the cost per book falls sharply, and it keeps falling as the quantity rises.
What you take on in exchange is everything print on demand was insulating you from.
- You pay up front, in full, before a single copy sells.
- You store them. Boxes of books are heavy, take up a room, and dislike damp.
- You ship them. Every direct order is a package you pack, label and post.
- Unsold copies are a loss. Stock you already paid for does not get cheaper to keep.
- The files are frozen. What you sent to the plate is what you have, times the whole run.
None of that makes a run irrational. It makes it a commitment that has to be justified by something other than optimism.
The honest threshold
The question is not whether you believe in the book. It is whether you already know where the copies go.
A run makes sense when demand exists before the print. A backlist that sells steadily. A direct-sales channel of your own — a website, a mailing list — where you keep the full margin instead of a retail share. An event schedule: festivals, markets, school visits, a speaking circuit where you sell from a table and cannot wait for a courier. A bookstore or library order in hand, or a bulk order from an organization buying copies for its members. In each case you are printing against demand you can point at.
A run does not create demand. This is the expensive mistake. A garage full of stock does not make a book more findable, more reviewed or more wanted. If the reason for the run is that a lower unit cost would make the numbers work, the numbers do not work yet — the missing piece is readers, and a print run does not buy any.
The test is blunt: can you name, today, the channel that moves the copies? If the answer involves the word hopefully, print on demand.
In the Cover Maker. The wrap is cut to your printer's own geometry, with the spine computed from the real page count and paper — so whether the file goes to a print-on-demand service or an offset printer working from their own template, the measurements come from the book you actually made.

What the two actually cost
Do not trust a per-copy figure or a break-even quantity from an article, including this one — they move with paper prices, currency and the specific job. What sets them is stable enough to reason about:
- Page count and paper. The biggest input on both. A long book costs more to print, every copy, forever.
- Trim size. Standard sizes are cheaper because they cut efficiently from the press sheet — see Choosing a trim size.
- Interior ink. Black-only is the cheap case. Color is the expensive case on demand, and much less so on a run.
- Binding. Paperback, case laminate and dust jacket each cost differently: Paperback, hardcover, dust jacket: what changes.
- Quantity, but only for offset. On demand, a thousand copies cost a thousand times one copy.
- Shipping and handling, which only the run has. A pallet to you, then copies to readers — a real budget line, usually underestimated.
Where the run genuinely wins
Beyond unit cost, a run buys things print on demand cannot supply.
Color and special finishes. A full-color children's book, an art book, a cookbook: punishing per copy on demand, ordinary on a run. Foil, spot gloss, embossing, printed endpapers and colored head-and-tail bands are run-only for most authors.
Materials. More paper weights and shades, more binding styles, sewn bindings, cloth. A print-on-demand service gives you a short menu; a printer running a job gives you a catalog.
Corrections go the other way. Find a typo in a print-on-demand book and you upload a corrected interior; the next copy printed is the fixed one, and nothing is wasted. Find it in a run and you own that typo until the boxes are empty. Read a proof properly either way — Order the proof. Then read it in daylight.
The hybrid
Most authors who do both end up in the same place: print on demand for retail, so the book is available everywhere with no stock and no risk, and a small run for events and direct sales, where the better margin and having copies in hand are what matter. The retail listing never depends on the run, so if the boxes sell slowly, nothing breaks.
Start on demand. Move to a run when you can name the copies' destination before you pay for them.
Make yours
Everything here is built into the tools, and they are free to use: name your book, bring your manuscript or your artwork, and work as long as you like. You only pay when you want the files without the preview watermark.
