Are there any limitations with shrink wrap sublimation?

Although I consider sublimation shrink wrap a miracle worker, it can’t prevent the printed transfer from wrinkling as it is forced to conform to a curved substrate. For curvy stemless wine glasses, for example, I recommend trimming the printed image in a way that allows it to better fit the product’s shape. Trimming and then taping the pieces down is a technique that works well for certain types of designs, but not all.
