1. A method of manufacturing a building panel having a structured surface with a design that comprises colour variation in register with the structure whereby the method comprises the steps of:
- applying a layer comprising a mix of fibres, binder, wear resistant particles, and a coloring substance on a carrier wherein the mix is floatable under heat and pressure; and
applying heat and pressure on the mix by a structured matrix comprising protrusions and cavities such that a controlled floating of the mix is obtained by the varying pressure distribution applied on the surface.

Abstract
A wood fibre based panel with surfaces layer with lower parts which has less binders than the upper parts. Also, a method of manufacturing a building panel having a structured surface with a design that has colour variation in register with the structure obtained by a varying pressure distribution applied on the surface.

- 12. A building panel comprising a decorative surface layer connected to a core wherein the surface layer is a mix comprising fibres, coloring substance, a binder and wear resistant particles, and wherein the surface layer comprises lower parts and upper parts, wherein there is a binder concentration gradient between the lower parts and upper parts.

18. A method of manufacturing a building panel having plain coloured surface whereby the method comprises the steps of:
-
applying a layer comprising a mix of fibres, binder, wear resistant particles, and a coloring substance, on a carrier wherein the mix is floatable under heat and pressure; and applying heat and pressure on the mix, wherein the mass ratio between resins and fibres is less than about 90%. - View Dependent Claims (19)

20. A method of manufacturing a building panel having plain coloured surface whereby the method comprises the steps of:
-
applying a layer comprising a mix of fibres, binder, wear resistant particles, and a coloring substance, on a carrier wherein the mix is floatable under heat and pressure; and applying heat and pressure on the mix, wherein the mass ratio between the binder and the sum of the masses of the fibres and the coloring substances is higher than about 60%. - View Dependent Claims (21, 23)
