Abstract

A method may be provided for manufacturing coated panels of the type including at least a substrate and a top layer with a motif. The top layer may be provided on the substrate. The method may involve providing a synthetic material layer on the substrate. A relief may be provided on the surface of said synthetic material layer provided on the substrate. The relief may include a pattern of recesses. The pattern may be at least partially determined by at least one print that is applied by inkjet printing. The relief may be obtained by printing a mask directly on or in the synthetic material layer. After providing the mask, the synthetic material layer may be cured. The mask may provide for selective curing of the synthetic material layer, such that the synthetic material layer is not solidified or solidified at a lesser extent in correspondence of the mask. The not solidified or less solidified portions of the synthetic material layer may be removed by performing a material-removing treatment on the synthetic material layer thereby obtaining the relief.

First claim

What is claimed is:

1. A method for manufacturing coated panels of the type including at least a substrate and a top layer with a motif, the top layer being provided on the substrate, the method comprising:
providing a synthetic material layer on the substrate; and
providing a relief on the surface of said synthetic material layer provided on the substrate;
wherein the relief includes a pattern of recesses;
wherein the pattern is at least partially determined by at least one print;
wherein the print is applied by inkjet printing;
wherein the relief is obtained by printing a mask directly in the synthetic material layer;
wherein after providing the mask, curing the synthetic material layer;
wherein the mask provides for selective curing of the synthetic material layer, such that the synthetic material layer is not solidified or solidified at a lesser extent in correspondence of the mask;
removing the mask and the not solidified or less solidified portions of the synthetic material layer by performing a material-removing treatment on the synthetic material layer thereby obtaining the relief;
wherein the synthetic material layer is a translucent or transparent synthetic material layer that is situated above the motif;
wherein the motif is a printed motif that is obtained by performing a print directly on the substrate by an inkjet printer with one or more print heads; and
wherein the coated panels are ceiling panels, floor panels, or furniture panels.

2. The method according to claim 1 , wherein the mask comprises masking portions; and
wherein wax or paraffin is applied for the masking portions.

3. The method according to claim 1 , wherein the mask includes masking portions that are formed in line and/or at the same time with providing the relief in the synthetic material layer.

4. The method according to claim 1 , wherein the selective curing is performed using UV or electron beams.

5. The method according to claim 1 , wherein the material-removing treatment comprises at least a suction treatment.

6. The method according to claim 1 , wherein the material-removing treatment comprises at least a mechanical treatment.

7. The method according to claim 1 , wherein the material-removing treatment comprises rinsing away portions of the synthetic material layer.

8. The method according to claim 1 , wherein the material-removing treatment comprises a chemical etching technique.

9. The method according to claim 1 , wherein the material-removing treatment involves removing the mask.

10. The method according to claim 1 , wherein the synthetic material layer is a translucent or transparent synthetic material layer that is situated above the motif.

11. The method according to claim 1 , wherein the motif is a printed motif that is obtained by performing a print directly on the substrate by an inkjet printer with one or more print heads.

12. The method according to claim 1 , wherein the motif and/or the relief are provided directly on panels already having approximately or completely the dimensions of final coated panels.

13. The method according to claim 1 , wherein the relief corresponds to the motif.

14. The method according to claim 1 , wherein the synthetic material layer comprises particles.
