Product Usage Instructions When performing heat sublimation transfer on ceramic coasters, first identify the sublimation surface to avoid mistakes. Set the machine pressure to 0.2 MPa (maintain the set value stably without additional pressure), control the temperature at 180-190 (356-374 F), and keep the pressing time at 200-220 seconds. After transfer, let the coaster cool naturally to room temperature before removing it this ensures perfect transfer and effectively prevents the coaster from cracking.
