A method for printing thermoplastic floor tiles involves printing tiles in a horizontal position with UV-drying ink, drying the ink (after application in the case of direct printing or before in the case of indirect printing), then applying a protective coating and drying the coating. - A method for printing and protecting the print on thermoplastic floor tiles, involves (a) positioning at least one prefabricated tile (1) so that at least one of the sides (5, 5') to be printed is horizontal, (b) applying at least one layer (6) of UV-drying ink to at least part of that surface (5, 5'), drying being effected after application to the surface for a direct print or before application for an indirect print, (c) applying protective coating(s) (9) to the top layer of ink and (d) drying the protective coating (9). An INDEPENDENT CLAIM is also included for apparatus for printing thermoplastic floor tiles, comprising a means of supporting tiles in a horizontal position (especially a table, tray or conveyor belt), a system for depositing layer(s) of UV-drying ink (e.g. a direct printing station for silk-screen printing or micro-drop deposition, or an indirect printing station for thermal transfer processes), a system for applying a protective coating (especially a varnishing station) and a UV-drying unit, preferably comprising UV lamps emitting in the 220-440 range. |
