Print-on-demand sites and services are sites where your printing is done in smaller quantities based on the order placed. These are mainly based on customer needs, unlike Publishing houses and Garment companies which print things such as books or apparel in bulk.
On these Print-on-demand sites you can print on; home decor, clothes, mugs, bags, mobile cases, stickers and books,…etc. The benefits of these types of sites to artists is that they let an artist upload their ready made designs to the print-on-demand sites, then in return they get paid for the items that have been purchased by buyers visiting the sites (see the sites terms for rates).
For artist, these are excellent platforms to upload their works to get noticed and packaged into a finalized product and be sold with no upfront type payments on the artists designs.
Here are a few of the latest Print-on-demand sites: Zazzle, Redbubble, TeeSpring, Society6 and Printful. Enjoy!
