Abstract

A method for producing a pattern, in particular a wood pattern, on the face of a woodbased-material board. The pattern is preset with the aid of a digital data set and applied to the woodbased-material board via an intaglio printing process. The pattern is covered with at least one synthetic resin layer and pressed with the woodbased-material board. The digital data set is used to produce a sample print by use of an inkjet printing process, which print is used to compare with the pattern print on the woodbased-material board in terms of optical appearance. The materials and/or printing conditions used in the pattern printing and the sample printing are coordinated with one another.

Claims

1. A device for printing, coating and pressing two different base materials with a same pattern, which is covered with a synthetic resin and subsequently pressed therewith, wherein the device comprises a first printing line and a second printing line, a pattern is applied to a first base material as a sample print using an inkjet printer in the first printing line and a same pattern is applied to a second base material using an intaglio printing device in the second printing line, and a test unit provided on an exit side with an optical scan element and a comparison unit compares the printing results of the first and second printing line with respect to optical appearance.

2. The device according to claim 1, wherein the optical scan element has a control unit in which results obtained in a scanning process are compared to a preset data set, and if there is conformity or if the deviations are acceptable a switching pulse is transmitted to control the second printing line.

3. The device according to claim 1, wherein the pattern is applied with an indirect intaglio printing device in the second printing line.

4. The device according to claim 1, wherein identical printing liquids or printing inks are used for the pattern applied to the first base material and the second base material.

5. The device according to claim 1, wherein the first base material and the second base material are same base materials.

6. The device according to claim 5, wherein the same base materials are woodbased-material, synthetic, stone or linoleum boards.

7. The device according to claim 5, wherein the same base materials are decorative papers.

8. The device according to claim 1, wherein the first base material and the second base material are provided with a chamfer on at least two opposite edges.

9. The device according to claim 1, wherein the pattern is applied with an indirect intaglio printing device in the second printing line in which printing liquids are applied to the second base material indirectly via a rubber roll in order to even out irregularities.

10. The device according to claim 1, wherein the optical scan element is a charge-coupled device.

11. The device according to claim 10, wherein the optical scan element contains a control unit in which results obtained in a scanning process are compared to a preset data set.

12. The device according to claim 11, wherein when conformity or deviations are acceptable, a switching pulse will be transmitted to control the second printing line.

13. The device according to claim 11, wherein the synthetic resin contains melamine resin or resinous resin which is coated on a woodbased-material board.

14. The device according to claim 13, wherein corundum particles are embedded into the synthetic resin.

15. The device according to claim 14, wherein the synthetic resin is pressed with the printed woodbased-material board in a short-cycle press.
