Print on demand

Print on demand means no copy exists until somebody orders it. The book is held as a file, and a press produces a single copy after payment rather than a print run being made in advance and warehoused. For personalized books this is not an efficiency choice; it is the only way the product can exist at all, because no two copies are the same.

The mechanics are straightforward. When an order is placed, a print-ready file is generated and sent to a printing partner, usually one with a facility near the delivery address. That facility prints the pages, binds them, trims the block, and posts the finished book directly, so it never passes through the seller's hands.

The trade-off against traditional printing is time versus uniqueness. A mass-printed book sitting in a warehouse ships the same day; a print-on-demand book needs a production window of a few days before it can be posted. What you get for those days is a book that has never been made before and will never be made again.

There are quality implications worth knowing. Print on demand uses digital presses rather than offset lithography, which historically meant a visible gap in colour fidelity. That gap has largely closed for illustrated children's books, though very large print runs are still cheaper per copy and can hit colours that digital presses reach only approximately.

It also changes what can be sold. Because there is no inventory risk, a catalogue can carry ninety-four stories rather than the six that would justify a print run, and a story that sells twice a year costs nothing to keep listed. Long-tail titles that would never survive a traditional publisher are viable under this model.

The term is often shortened to POD, and it sits alongside two related ideas: made to order, which means the same thing in plainer English, and drop shipping, which is about who posts the parcel rather than when it was printed.
