Print on demand (POD) is a dropshipping business model that allows producing printed apparel and products without an upfront investment.
Using the latest printing methods — direct-to-garment (DTG) printing and all-over printing (AOP) — it is possible to produce one-off printed items at a low cost.
When using the traditional printing methods, such as screen printing, it typically requires ordering printed stock in bulk to make it economically viable. This inherently involves some risk on the merchants' part, as they will have invested their capital in the production of the goods.
The POD business model eliminates this risk, since all stock is printed only when you've made a sale, thus allowing you to start a business with little to no capital.
