Step-By-Step Guide

1. Turn on your heat press. Set the temperature to 400°F / 205°C (temperatures based on prints made with small desktop sublimation printers). Strong pressure is recommended. (settings may vary based on equipment). Add a sheet of protection paper (blowout paper) on the bottom plate of the heat press.
2. Take your blank and peel the protection film from the bare coaster (coasters without cork on the back do not generally have film). Clean the surface of the coaster with a cleaning cloth and some all-purpose cleaning uid.
3. Clean the surface with all-purpose cleaner, a cloth, and compressed air. 
4. Put your printed transfer face-up on a at table. Put your blank gently face-down on the printed transfer. Line up and center the coaster on the printed transfer. Add heat tape on both sides of the item.
5. Add everything in the center of the bottom plate of the heat press. Be sure that your printed transfer is face-down on the bottom plate. Set the correct temperature & time (see step 6). Close the heat press so the sublimation process starts.
6. When the sublimation process stops, remove immediately the transfer paper and allow the product to cool down. Attention: the item will be hot, so wear protective heat gloves.
