My process:
I use Sublimation paper for my designs. I will cut out the design using my Cricut machine from art or text I have created or purchased. I then use my Heat Press machine to move the ink to the neoprene coaster.
This process is permanent. The ink becomes part of the coaster’s surface, and won’t wear of for a very long time.
Sublimation is when a solid turns directly into a gas without becoming liquid. This happens when the solid's molecules gain enough energy to break free, usually through heat or lower pressure. As the temperature rises, the molecules move faster. When the solid gains enough energy, its molecules escape into the air as gas.
