Abstract

A method for forming a decorative design ( 2 ) on an element ( 1 ) of a wood-based material, including providing an element ( 1 ) of a wood-based material having a surface ( 3 ), the surface ( 3 ) being solid and being formed of the wood-based material, and printing a decorative design ( 2 ) with an aqueous ink on at least a portion of the surface ( 3 ) by means of a digital printing device. Also, a building element including such an element.

First claim

The invention claimed is:

1. A method for forming a decorative design on an element of a wood-based material, the method comprising:
providing an element of a wood-based material having a surface, said surface being solid and being formed of said wood-based material;
applying a primer adapted to control bleeding of said ink on at least a portion of said surface, wherein the primer is a UV curable primer; and
printing a decorative design with an aqueous ink on at least the portion of said surface by means of a digital printing device.

2. The method according to claim 1 , wherein the wood-based material is solid wood or wood veneer.

3. The method according to claim 1 , wherein the digital printing device comprises a Drop-on Demand (DOD) inkjet printer.

4. The method according to claim 1 , wherein said aqueous ink is a heat sensitive curing ink.

5. The method according to claim 1 , wherein the primer is applied by means of digital printing.

6. The method according to claim 1 , further comprising applying a protective surface layer on top of the decorative design.

7. The method according to claim 6 , wherein the protective surface layer comprises one or several lacquer layers of a UV curable lacquer or a polyurethane lacquer.

8. The method according to claim 1 , wherein said element forms a surface layer of a building panel.

9. The method according to claim 1 , wherein the primer comprises at least one monovalent metallic salt being Na + .
