Abstract:

A method of making permanent drawings and markings on a mosaic tile having a grid frame with a plurality of replaceable plastic tiles or tiles made of polycarbonate material. The method comprises the steps of providing a plurality of separate and replaceable tiles on a grid frame of the mosaic tile; providing an ink-jet printer having an ultraviolet stable ink; spraying the ultraviolet stable ink out from the ink-jet printer onto the plurality of replaceable tiles of the mosaic tile to form an image, and exposing an ultraviolet light on the image to cure the ultraviolet stable ink onto the plurality of replaceable tiles of the mosaic tile. The method further comprises the step of replacing an old tile with a new tile having the same marking or new markings as the old file. The method causes the ink to be embedded onto the files and remain in a very permanent state.
