Abstract

The present disclosure relates to a method for producing a structured decorative panel, comprising the method steps: a) providing a film that is to be structured; b) providing a stamping means for structuring the film; c) structuring the film using the stamping means so as to form at least one structured region on the film; d) ascertaining at least one dimension of at least one structured region after method step c); e) providing a substrate; f) applying a decoration to the substrate; wherein g) the at least one dimension of the structured region ascertained in method step c) is taken into consideration during the application of a decoration to the substrate; and h) applying the film to the substrate in such a way that the at least one structured region is synchronous with the decoration.

First claim

The invention claimed is:

1. A method for producing a structured decorative panel, comprising the method steps:
a) providing a film that is to be structured;
b) providing an embossing means for structuring the film;
c) structuring the film using the embossing means so as to form at least one structured region on the film;
d) ascertaining at least one dimension of at least one structured region after method step c);
e) providing a substrate;
f) applying a decoration to the substrate, wherein
g) the at least one dimension of the structured region ascertained in method step c) is taken into consideration during the application of a decoration to the substrate; and
h) applying the film to the substrate in such a way that the at least one structured region is synchronous with the decoration.

2. The method according to claim 1 , wherein the at least one dimension includes the length of the structured region.

3. The method according to claim 1 , wherein the at least one dimension includes the width of the structured region.

4. The method according to claim 1 , wherein the film comprises an acrylic-based plastic compound, in particular a polyurethane-modified acrylic plastic compound, polypropylene, or polyethylene terephthalate.

5. The method according to claim 1 , wherein method step f) is performed using a digital printing process.

6. The method according to claim 1 , wherein at least one of an embossing cylinder, a embossing band, and a metal embossing sheet is used as the embossing means.

7. The method according to claim 1 , wherein method step g) is performed by using existing decoration data associated with corresponding dimensions, or by performing a computational correction of decoration data based on the dimension.

8. The method according to claim 1 , wherein the embossing means has a neutral region adjacent to at least one structure-embossing region in the longitudinal direction.

9. The method according to claim 8 , wherein the neutral region at least partially has a structure different from the structure-embossing region.

10. The method according to claim 8 , wherein the neutral region at least partially comprises a structure-free region.

11. The method according to claim 8 , wherein the film is applied in the longitudinal direction to a plurality of substrates, each substrate comprising a surface that is to be structured, the surfaces that are to be structured of different substrates being spaced apart, and the distance between the surfaces that are to be structured corresponding to the length l 1 of a neutral region.

12. The method according to claim 1 , wherein a registration mark is applied to the decoration and the film.

13. The method according to claim 1 , wherein a plastic-containing substrate is used as the substrate.

14. The method according to claim 1 , wherein process parameters and dimensional change data of a film are stored and are compared to process parameters and dimensional change data of the film or another film during a structuring at a later point in time.

15. A system for producing a decorative panel, comprising:
an embossing means for structuring a film that is structured to form at least one structured region on the film;
a dimensioning means for ascertaining at least one dimension of at least one structured region after the embossing of the film;
a decoration means for applying a decoration to a substrate, wherein the at least one dimension of the structured region is taken into consideration during the application of the decoration to the substrate; and
a merging device for applying the film to the substrate in such a way that the at least one structured region is synchronous with the decoration.
