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 method for producing a same pattern comprising a plurality of image points on respectively one side of two different base materials from an original digital data set comprising:

printing a pattern on one side of a first base material as a sample print;

covering the pattern with a synthetic resin layer;

pressing the first base material with the pattern and the synthetic resin layer;

printing the pattern on one side of a second base material;

covering the pattern on the second base material with a synthetic resin layer;

pressing the second base material with the pattern and the synthetic resin layer, wherein

the original digital data set controls the printing on the first base material and the second base material so that a number of image points per unit area on the first base material essentially corresponds to a number of image points per unit area on the second base material and a size of the image points and nozzle spacings of the printing on the first base material are coordinated with a size of screen dots and raster sizes in a printing process of the second based material and identical printing liquids are used for the printing of the pattern on the first base material and the second based material.

2. The method according to claim 1, wherein identical solvents, pigments and binders are used for printing liquids.

3. The method according to claim 1 wherein Ma woodbased-material board, a plastic board, a stone slab, a linoleum board or a decorative paper is used as a base material.

4. The method according to claim 3, wherein a surface structure synchronous to the pattern is embossed during the pressing of the first and second base materials with the pattern and the synthetic resin layer.

5. The method according to claim 3, wherein the first base material and the second base material are provided with a chamfer on at least two opposite edges.

6. The method according to claim 1, wherein the raster of a print roller for intaglio printing is produced by a laser, an etching process or an erosion process.

7. The method according to claim 6, wherein the printing of the pattern on the second base material is carried out in an indirect intaglio printing process.

8. The method according to claim 1, wherein the printing a pattern on the first base material as a sample print is performed with an inkjet printer.

9. The method according to claim 1, wherein the printing a pattern on the second base material is performed by a print roller with a raster in an intaglio printing process.

10. The method of claim 1, wherein:

the printing a pattern on the first base material as a sample print is performed with an inkjet printer;

the printing a pattern on the second base material is performed by a print roller; and

the original digital data set controls the inkjet printer and produces the print roller so that the number of image points per unit area on the first base material essentially corresponds to the number of image points per unit area on the second base material and the size of the image points and the nozzle spacings of the inkjet printer are coordinated with the size of the screen dots and the raster sizes in intaglio printing process.

11. A method of printing, comprising:

providing a pattern in a form of original data;

generating a data set used in a printing process generated from the original data;

printing a first material board using the data set;

coating the first material board with at least a first synthetic resin-based layer;

pressing the at least first synthetic resin layer with the printed first material board in a short-cycle press;

generating a further data set from the original data as the basis for an indirect printing process;

adding control parameters for controlling a laser to the original data; and

engraving a print roller according to the original data with aid of the control parameters, wherein the further data set and the data set are analogously generated from the original data by addition of respective corresponding control parameters;

printing the pattern on one side of a second material board with the print roller using the further data set;

covering the pattern on the second material board with a synthetic resin layer; and

pressing the second material board with the pattern and the synthetic resin layer.

12. The method according to claim 11, wherein the providing a pattern is obtained by photographing an original pattern by a digital camera.

13. The method according to claim 11, wherein the at least first synthetic resin layer contains melamine resin or resinous resin.

14. The method according to claim 13, wherein the at least first synthetic resin layer contains embedded corundum particles,

15. The method according to claim 11, wherein the data set contains additional control data or control parameters to control inkjet nozzles.

16. The method according to claim 11, wherein the original data controls the printing on the first material board and the second material board so that a number of image points per unit area on the first material board essentially corresponds to a number of image points per unit area on the second material board and a size of the image points and nozzle spacings of the printing on the first material board are coordinated with a size of screen dots and raster sizes in a printing process of the second material board and identical printing liquids are used for the printing of the pattern on the first material board and the second material board.

17. 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.

18. The device according to claim 17, 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.

19. The device according to claim 17, wherein the pattern is applied with an indirect intaglio printing device in the second printing line.
