A method for producing a decorative surface on a workpiece is disclosed, the method comprising: feeding of the workpiece coated with a liquid layer to a digital printing station and application of an agent capable of at least partially absorbing electromagnetic radiation, at least on a partial area of the surface of the liquid layer (2), or which, in contact with the surface, produces a reaction product which is capable of at least partially absorbing electromagnetic radiation.

A decorative material that can give an excellent three-dimensional effect, has a large change in shadowed parts depending on observation angle, and has advanced design aesthetics is provided. A decorative material, wherein on a first principal surface side, a plurality of independent closed regions each having a groove-shaped parallel recess and projection pattern are arranged, depths of recesses of the groove-shaped parallel recess and projection patterns vary in at least some of the closed regions, and a coloring agent is filled in at least part in a depth direction of recesses of the groove-shaped parallel recess and projection pattern in each of the closed regions.
