Tile edge systems and methods
Disclosed herein are tiles, systems, and methods related to manufacturing bullnose or other non-straight edge tiles. In a method of manufacturing a bullnose tile, the method comprises the steps of providing a tile, wherein the tile is a fired ceramic tile comprising a base and a decoration; cutting or milling the tile to form a bullnose edge; transporting the tile to at least a first printing station; printing at least one print layer of print media on the bullnose edge; transporting the tile to a curing station and curing the print media to provide the bullnose tile.
1. A method of manufacturing a bullnose tile, comprising:
providing a tile, wherein said tile is a fired ceramic tile comprising an undecorated base and a decoration comprising a color and pattern;
cutting or milling the tile to form a bullnose edge, wherein the cutting or milling provides a cut revealing the undecorated base;
transporting the tile to a single printing station;
printing multiple print layers of print media on the bullnose edge with the printing station comprising an inkjet printer with print heads that are disposed at an angle to a top surface of the tile, the multiple print layers matching one or both of the color and pattern of the decoration;
transporting the tile to a single curing station and curing the print media by ultraviolet (UV) radiation to provide the bullnose tile, the step of curing the print media comprising curing all layers of the multiple print layers together after all layers of the multiple print layers are applied;
after curing the print media, transporting the bullnose tile to a coating station and applying a radiation curable clear protective coat on the bullnose tile;
curing the radiation curable clear protective coat by UV radiation to provide a finished bullnose tile;
transporting the finished bullnose tile to a sorting and/or packaging station immediately after the step of curing the radiation curable protective clear coat; and
sorting and/or packaging at least one finished bullnose tile, wherein the multiple print layers are layers of inks comprising organic and/or inorganic pigments, and
wherein the inks comprise cyan, magenta, yellow and black ink.
2. The method of claim 1 , wherein the print media comprises one or more radiation curable ink.
3. The method of claim 2 , wherein curing the print media comprises exposing the print media to a radiation lamp.
4. The method of claim 1 , wherein the print media comprises a base coat or tie coat.
5. The method of claim 4 , wherein the base coat is a white coat or a solid colored coat.
6. The method of claim 1 , comprising applying a base coat or tie coat on the bullnose edge, and curing the base coat or tie coat.
7. The method of claim 6 , wherein printing comprises printing a decorative coat on top of the base coat or tie coat.
8. The method of claim 1 , wherein the radiation curable clear protective coat is applied by means of rollers, sprayer or dispenser.
9. The method of claim 1 , wherein the radiation curable clear protective coat is applied on top of a decorative coat.
10. The method of claim 1 , wherein the tile is transported on an in-line conveyor system during cutting, printing, and curing the print media.
11. The method of claim 1 , wherein the cutting is wet cutting, and wherein the bullnose tile is dried after the wet cutting.
12. A method of manufacturing a bullnose tile, comprising:
providing a tile, wherein said tile is a fired ceramic tile comprising an undecorated base and a decoration;
comprising a color and pattern cutting or milling the tile to form a bullnose edge, wherein the cutting or milling provides a cut revealing the undecorated base;
transporting the tile to a single printing station;
printing multiple print layers of print media on the bullnose edge with the printing station comprising an inkjet printer with print heads that are disposed at an angle between 30 degrees and 60 degrees to a top surface of the tile, the multiple print layers matching one or both of the color and pattern of the decoration;
transporting the tile to a single curing station and curing the print media by ultraviolet (UV) radiation to provide the bullnose tile, the step of curing the print media comprising curing all layers of the multiple print layers together after all layers of the multiple print layers are applied;
after curing the print media, transporting the bullnose tile to a coating station and applying a radiation curable clear protective coat on the bullnose tile;
curing the radiation curable clear protective coat by UV radiation to provide a finished bullnose tile;
transporting the finished bullnose tile to a sorting and/or packaging station immediately after the step of curing the radiation curable protective clear coat; and
sorting and/or packaging at least one finished bullnose tile,
wherein the multiple print layers are layers of inks comprising organic and/or inorganic pigments, and wherein the inks comprise cyan, magenta, yellow and black ink.
