Abstract
Building panels and a method to produce such panels including a solid decorative surface having a decorative wear layer including fibres, binders, colour substance, wear resistant particles and a digital ink print.
Claims33
A method for producing a decorative surface layer, comprising the steps of:
- applying a first powder, in powder form, on a substrate to form a first powder layer;
- printing a first print with first ink drops on the first powder layer;
- spraying a first colored liquid substance on the first powder layer;
- applying a second powder, in powder form, on the first powder layer to form a second powder layer after the printing of the first print and the spraying of the first colored liquid substance on the first powder layer;
- printing a second print with second ink drops on the second powder layer;
- spraying a second colored liquid substance on the second powder layer;
- and
- pressing the first and second powder layers to form the decorative surface layer, wherein
- the printing of the first and second prints is performed by controlling a printed position of each ink drop, and
- the spraying of the first colored substance is performed by randomly distributing the first colored substance over a first sprayed area and the spraying of the second colored substance is performed by randomly distributing the second colored substance over a second sprayed area,
- wherein at least some of the second ink drops positioned over at least some of the first ink drops are in direct contact with the at least some of the first ink drops.

A method for producing a decorative surface layer, comprising the steps of:
- applying a first powder, in powder form, on a substrate to form a first powder layer, the first powder comprising first color pigments;
- printing a first print with first ink drops on the first powder layer;
- spraying a first colored liquid substance on the first powder layer;
- applying a second powder, in powder form, on the first powder layer to form a second powder layer after the printing of the first print and the spraying of the first colored liquid substance on the first powder layer, the second powder comprising second color pigments;
- printing a second print with second ink drops on the second powder layer;
- spraying a second colored liquid substance on the second powder layer;
- and
- pressing the first and second powder layers to form the decorative surface layer, wherein
- the printing of the first and second prints is performed by controlling a printed position of each of the first and second ink drops, and
- the spraying of the first colored substance is performed by randomly distributing the first colored substance over a first sprayed area and the spraying of the second colored substance is performed by randomly distributing the second colored substance over a second sprayed area,
- wherein at least some of the second ink drops positioned over at least some of the first ink drops are in direct contact with the at least some of the first ink drops.

- printing a first print with first ink drops on the first powder layer;
- applying a second powder, in powder form, on the first powder layer to form a second powder layer;
- printing a second print with second ink drops on the second powder layer, the second ink drops being larger than the first ink drops printed on the first powder layer;
- and
- applying heat and pressure on the first and second powder layers on the substrate to cure the first and second powder layers into the decorative surface layer which possesses the first print and the second print,
- wherein at least some of the second ink drops positioned over at least some of the first ink drops are in direct contact with the at least some of the first ink drops.

A method for producing a decorative surface layer, comprising the steps of:
- applying a first powder, in powder form, on a substrate to form a first powder layer;
- printing a first print with first ink drops on the first powder layer, wherein the first ink drops are of variable size;
- spraying a first colored liquid substance on the first powder layer;
- applying a second powder, in powder form, on the first powder layer to form a second powder layer after the printing of the first print and the spraying of the first colored liquid substance on the first powder layer;
- printing a second print with second ink drops on the second powder layer;
- spraying a second colored liquid substance on the second powder layer, the second colored liquid substance being a different color than the first colored liquid substance;
- and
- pressing the first and second powder layers to form the decorative surface layer,
- wherein at least some of the second ink drops positioned over at least some of the first ink drops are in direct contact with the at least some of the first ink drops.
