Abstract

A process for the manufacturing of surface elements is provided herein. The surface elements can include a decorative upper layer and a supporting core. A supporting core with a desired format is manufactured and provided with an upper side and a lower side. The upper side of the supporting core is provided with a décor, by for example printing, which décor is positioned after a predetermined fixed point on the supporting core. The upper side of the supporting core is provided with a protecting, at least partly translucent, wear layer by for example spray coating, roller coating, curtain coating and immersion coating or by being provided with one or more sheets of α-cellulose impregnated with thermosetting resin or lacquer.

Claims (18)

1. A process for manufacturing a panel, the process comprising:

providing a supporting core with an upper side, wherein the supporting core comprises medium density fiber board;

printing a decor on the upper side of the supporting core using a digital printer, the decor being achieved by digitizing an actual archetype or creating the decor in a digital medium, wherein the digital printer is selected from the group consisting of a printer of the inkjet type and a printer of the electrostatic type, wherein the printing is performed with at least four different colors selected from the group consisting of yellow, magenta, cyan, black, white, light magenta and light cyan;

providing a wear layer on the upper side of the supporting core, wherein the wear layer comprises melamine-formaldehyde resin and hard particles; and

pressing a matrix towards the wear layer whereby the wear layer receives a surface structure that enhances the realism of the decor.

2. The process according to claim 1 , wherein the décor is printed at a resolution of up to 1500 dots per inch (dpi).

3. The process according to claim 1 , wherein the digital printer comprises a digital inkjet printer.

4. The process according to claim 1 , wherein the printing comprises directly printing the decor on the upper side of the supporting core.

5. A process for manufacturing a surface element, the process comprising:

providing a supporting core with an upper side, wherein the supporting core comprises medium density fiber board;

printing a decor on the upper side of the supporting core using a digital printer, the decor being a digital image, wherein the digital printer is selected from the group consisting of a printer of the inkjet type and a printer of the electrostatic type, wherein the printing is performed with at least four different colors selected from the group consisting of yellow, magenta, cyan, black, white, light magenta and light cyan;

providing a wear layer on the upper side of the supporting core, wherein the wear layer is joined to the core through heat and pressure, wherein the wear layer comprises melamine-formaldehyde resin and hard particles; and

pressing a matrix towards the wear layer whereby the wear layer receives a surface structure that enhances the realism of the décor;

wherein the surface element forms at least one of a floor element configured to be joined with corresponding floor elements to form a floor covering, a wall element configured to be joined with corresponding wall elements to form a wall covering, or ceiling element configured to be joined with corresponding ceiling elements to form a ceiling.

6. The process according to claim 5 , wherein the digital image is achieved by digitizing an actual archetype and/or creating the decor in a digital medium.

7. The process according to claim 6 , wherein the décor is printed at a resolution of up to 1500 dots per inch (dpi).

8. The process according to claim 6 , wherein the digital printer comprises a digital inkjet printer.

9. The process according to claim 6 , wherein the printing comprises directly printing the decor on the upper side of the supporting core.
