What is sublimation?
How Sublimation works is a special ink is heated that turns directly into a gas from a solid. This gas is then absorbed by the fibers of the product and resolidified. As a result, no ink is on the surface of the product.
Before switching to this new way of doing tumblers, we used resin. The process is twice as long and curing times for the resin took up to 2/3 days. In OUR OPINION sublimation looks better, last longer, and definitely lets us add more detail to your order.
