Print on demand is the reason you can order one custom t-shirt instead of fifty. Here is what it actually involves, and how it compares to the alternatives.
Print on demand, defined
Print on demand (POD) is a fulfilment model in which a garment is printed only after a customer orders it. No stock of finished designs is held. The blank garment sits in a warehouse; the design is applied when the order arrives, and the finished item ships directly to the buyer.
The consequence that matters to shoppers: there is no minimum order quantity, because there is no production run to fill.
How the printing itself works
Most POD apparel uses direct-to-garment (DTG) printing. A specialised inkjet printer sprays water-based ink directly into the fibres of the fabric. On dark garments, a white underbase is laid down first so colours stay accurate. The garment is then heat-cured to set the ink.
Because the ink bonds into the fibres rather than sitting on top of them, DTG prints feel soft rather than plasticky, and they do not crack the way older transfers did.
DTG vs screen printing vs heat transfer
- DTG (print on demand): unlimited colours, full photographic detail, no minimum order, soft finish. Cost per unit stays flat whether you buy one or a hundred.
- Screen printing: a separate stencil per colour. Very cheap per unit at high volume, expensive to set up, and impractical for detailed or multi-colour artwork. Typically needs 12-24 units minimum.
- Heat transfer vinyl: good for simple text and shapes, sits on top of the fabric, less breathable, and prone to peeling over time.
For a single custom shirt with a detailed design, DTG is the only one of the three that makes economic sense.
Where AI fits in
POD solved the manufacturing minimum, but the design bottleneck remained: you still had to produce artwork. AI image generation removes that step. At Wearlie, you describe a design in plain language, the AI generates print-ready artwork, and the garment is printed on demand and shipped. Idea to doorstep with no design software and no bulk order.
Frequently asked questions
Does print on demand quality match screen printing?
For detailed, multi-colour designs, DTG is generally better - screen printing struggles with gradients and photographic detail. For large runs of a simple one-colour logo, screen printing still wins on cost and opacity.
How long do print-on-demand shirts last?
Properly cured DTG prints survive dozens of wash cycles. Wash cold and inside out, tumble dry low, and avoid ironing the print directly.
Why does print on demand take longer to ship?
The item does not exist until you order it. Production time is added before the shipping clock starts.
Is print on demand more expensive?
Per unit, yes, compared with a bulk screen-printed run. In total, no - you are not buying 24 shirts to get one you want.
Is print on demand more sustainable?
Nothing is produced speculatively, so there is no unsold inventory to discard. That is a meaningful reduction in waste compared with stocking finished designs.
