Floor panel for forming a floor covering and method for manufacturing such floor panels
A method may be provided for manufacturing a floor panel having a substrate and a top layer. The top layer may have a decorative layer that includes a digital print and a transparent or translucent wear layer. The method may involve providing the substrate with the digital print by jetting one or more inks from a set of inks using a digital inkjet printer. The ink may include a binding agent that is present in an amount below 20 percent by weight of the ink. The translucent or transparent wear layer may be laminated on top of the digital print.
1. A method for manufacturing a floor panel having a substrate and a top layer, the top layer having a decorative layer that includes a digital print and a transparent or translucent wear layer, the method comprising:
providing the substrate with the digital print by jetting one or more inks from a set of inks using a digital inkjet printer, wherein the ink includes a binding agent that is present in an amount below 20 percent by weight of the ink;
providing the translucent or transparent wear layer; and
laminating the transparent or translucent wear layer on top of the digital print.
2. The method of claim 1 , wherein the binding agent comprise VC-VAC copolymer or polymer latexes, either acrylates or urethane components.
3. The method of claim 1 , wherein the binding agent is in an amount of at least 2 percent by weight of the liquid ink.
4. The method of claim 1 , wherein the set of inks comprises solvent based inks, UV based inks, or water-based inks.
5. The method of claim 1 , wherein the inks in the set of inks comprise pigments.
6. The method of claim 1 , wherein the set of inks is CMYK.
7. The method of claim 1 , wherein the digital print is performed directly on the substrate.
8. The method of claim 7 , wherein the digital print is performed directly with the intermediary of a preparative layer.
9. The method of claim 1 , wherein the digital print is performed on a film.
10. The method of claim 9 , wherein the film is a white or a uniformly colored film.
11. The method of claim 9 wherein the film is a thermoplastic film.
12. The method of claim 11 , wherein the film is a PVC film.
13. The method of claim 12 , wherein the PVC film incorporates less than 10% of a plasticizer.
14. The method of claim 9 , comprising laminating the film onto the substrate.
15. The method of claim 1 , wherein the translucent or transparent wear layer is made of a thermoplastic material.
16. The method of claim 15 , wherein the thermoplastic material is PVC.
17. The method of claim 15 , wherein the translucent or transparent wear layer has a thickness of 150 micrometers or more.
18. The method of claim 1 , comprising providing an additional binder or binding agent on the digital print.
19. The method of claim 18 , wherein the additional binder or binding agent is the same as the binding agent contained in the ink.
20. The method of claim 1 , comprising:
providing a lacquer layer as a liquid layer on the transparent or translucent wear layer and/or the decorative layer; and
subsequently solidifying the lacquer layer.
