Sublimation?
Sublimation is a process that allows us to put Photo Quality photos or
logos on ceramic or glass tile.

The photo or logo are turned into a gas that actually penetrates the
pores of the material, creating a photo quality image that is UV
resistant and as durable as the original material. You would have to
scratch the tile deeply to damage the image.

Don’t worry… the original photo or logo is not damaged in this
process!
