Apply sublimation transfer on the surface of the tumbler using heat tape. For full wrap designs, make sure you pull the transfer as tightly as possible around the tumbler, then tape very well along the seam and around the top/bottom of the tumbler. Pulling the tape/transfer as tight as possible with no air pockets. If your transfer does not fully cover the tumbler surface, apply blowout/butcher paper to the entire tumbler so that there is no metal showing on the sides.
Apply shrink wrap using a heat gun to shrink it tight to the tumbler.
Bake in a convection oven at approximately 385-400 degrees F for 5-6 minutes, turning halfway. **If your tumbler is touching a metal surface during baking, the shrink wrap will be more likely to melt!
Remove from oven and immediately remove shrink wrap and transfer. TUMBLER WILL BE HOT!! No sealant is necessary on sublimation tumblers. *Hand washing is recommended as the high heat in many dishwashers may reactivate the ink and cause it to bleed.
