Ceramic tile
Ceramic tile having a ceramic base layer and a cover glaze layer including a printed pattern, where the surface of the ceramic tile has a relief having structural features corresponding to the printed pattern. The relief being basically formed as a plurality of excavations present in the generally plane upper surface of the ceramic tile and the structural features have a depth such that they are completely situated above the ceramic base layer.
1. A ceramic tile having a ceramic base layer and a cover glaze layer comprising a printed pattern, wherein the tile is rectangular and oblong, wherein the surface of the ceramic tile comprises a relief having structural features corresponding to said printed pattern, wherein said relief is formed by a plurality of excavations in the surface of the ceramic base layer, and wherein said relief comprises irregular or random relief features, distributed essentially over the entirety of the surface of the ceramic tile, that are combined with the structural features that correspond to the printed pattern.
2. The ceramic tile according to claim 1 , wherein said printed pattern extends substantially over the entire surface of the ceramic tile.
3. The ceramic tile according to claim 1 , wherein said printed pattern represents a wood or stone pattern, representing only one one-piece wooden plank or stone tile over the entire surface of the ceramic tile.
4. The ceramic tile according to claim 1 , wherein said printed pattern is a wood pattern and said structural features are lines following the course of the grain lines of the wood pattern or a plurality of successive dashes having a configuration following the grain lines of the wood pattern.
5. The ceramic tile according to claim 1 , wherein said structural features have a depth such that they are completely situated above said ceramic base layer.
6. The ceramic tile according to claim 1 , wherein said cover glaze layer at least comprises a glaze layer of uniform color arranged underneath said printed pattern.
7. The ceramic tile according to claim 1 , wherein said cover glaze layer at least comprises a transparent glaze layer arranged over said printed pattern.
8. The ceramic tile according to claim 7 , wherein at least some of said structural features are formed in said transparent glaze layer.
9. The ceramic tile according to claim 1 , wherein said printed pattern is a digitally printed pattern.
10. The ceramic tile according to claim 9 , wherein said printed pattern is formed at least from the base colors cyan, magenta, yellow and black.
11. A method for manufacturing a ceramic tile, wherein said ceramic tile has a ceramic base layer and a cover glaze layer with a printed pattern, wherein the tile is rectangular and oblong, and wherein the method comprises the following steps:
the step of forming the ceramic base layer;
the step of providing a glaze layer on said ceramic base layer;
the step of printing a pattern on said glaze layer;
the step of firing the ceramic base layer with the glaze layer having the printed pattern;
wherein the method further comprises the step of forming a relief having structural features corresponding to said printed pattern, and in that said relief is basically formed as a plurality of excavations present in the generally plane upper surface of the ceramic tile, and in that said relief is formed on the surface of said ceramic base layer before said step of providing a glaze layer, and in that said relief comprises irregular or random relief features, distributed essentially over the entirety of the surface of the ceramic tile, that are combined with the structural features that correspond to the printed pattern.
