Print on demand companies print one offs products that you have placed your artwork or photograph on. There is no upfront cost and they offer a wide variety of products from framed prints, posters, coasters, back packs, T-shirts, Mugs and more.
There are numerous print on demand companies. Choosing which one is right for you can be challenging but worth the time and effort. If you sell products you are only as good as your manufacturer. This took me the longest time. Finding the right company, which charges the right amount for the right products.
