Bright white 10cm diameter ceramic coaster with sublimation coating Super smooth surface to bring out the best of your print Comes with a self-adhesive non-slip cork patch that you can stick on the bottom to prevent scratches on the ceramic or the surface it is on Can be printed on using a standard flat press. We usually recommend using a flat press rather than a clam press for ceramics to avoid the chance of chipping the ceramic Use in conjunction with a thin silicone mat (1.5mm ideally). This will help to create an even and consistent print across the whole item.
