Print on demand

Print on demand (POD) is a printing technology and business process in which book copies (or other documents, packaging, or materials) are not printed until the company receives an order, allowing prints in single or small quantities. While other industries established the build-to-order business model, POD could only develop after the beginning of digital printing, as it was not economical to print single copies using traditional printing technologies such as letterpress and offset printing.

As small presses adapt to the loss of key distributors, a growing number are exploring print‑on‑demand and other flexible printing methods to keep titles available without large offset print runs. Many academic publishers, including university presses, use POD services to maintain large backlists (lists of older publications); some use POD for all of their publications. Larger publishers may use POD in special circumstances, such as reprinting older, out-of-print titles or for test marketing.
