One approach to pricing sublimation products is what I call value pricing. Using this approach, you can often charge a higher price for your products because they are simply worth it. Most sublimators underprice their products and often deliver less-than-stellar designs. Doing so leaves money on the table and can cheapen the product sold.
Great service, quality, accuracy, and prompt delivery are all key components of a great product that you can charge more for too. My three elements to value pricing are substrates, artwork, and sales/marketing strategies.
