Method for applying a decoration to a composite wood board
View Patent ↗The invention relates to a method for applying a decoration to the upper face of a composite wood board, in particular a MDF or HDF board, wherein said method is characterized in that at least one second decoration produced by digital printing is applied to a first decoration produced by intaglio printing.
1. A method for applying a decoration to an upper side of a composite wood board, comprising a first decoration that is printed directly onto at least one upper side of the composite wood board by using gravure printing and at least one second decoration being applied to the first decoration by using digital printing, and applying a sealing layer as a base coat layer onto the upper side of the composite wood board before the first decoration is printed to prevent a printing ink from being absorbed by the composite wood board, wherein the first decoration comprises colors which define a basic color tone of a finished decoration and the at least second decoration comprises details which define the type of the finished decoration.
2. The method as claimed in claim 1 , wherein the first decoration is printed onto a paper layer which is connected to the composite wood board.
3. The method as claimed in claim 2 , wherein the second decoration is printed onto the first decoration on the paper layer before the paper layer is connected to the composite wood board.
4. The method as claimed in claim 3 , wherein the paper layer with the first decoration is present as a reel.
5. The method as claimed in claim 2 , wherein the paper layer is pressed with the composite wood board.
6. The method as claimed in claim 5 , wherein, after pressing with the composite wood board, the paper layer is cut to a size of the composite wood board.
7. The method as claimed in claim 2 , further comprising covering the second decoration by a transparent covering layer.
8. The method as claimed in claim 1 , wherein the upper side of the composite wood board is ground before the application of the first decoration.
9. The method as claimed in claim 1 , wherein the second decoration imitates a natural decoration.
10. The method as claimed in claim 1 , wherein the second decoration does not have any regions which are repeated in a pattern.
11. The method as claimed in claim 1 , wherein the second decoration has a random pattern.
12. The method as claimed in claim 7 , wherein the covering layer has a structural embossment which corresponds completely with the second decoration.
