Method and device for producing a decorative surface

A method for producing a decorative surface on a workpiece, comprising:

• I. applying a manipulation medium into or onto at least a part of a liquid layer located on the workpiece, wherein the applying is:
• I.a
• (I.a1) onto the part of the liquid layer located on the workpiece, wherein when the manipulation medium is applied at least onto the part of the liquid layer, the manipulation medium is configured for at least one of:
• displacing a portion of the liquid layer in relation to the workpiece;
• and
• at least partially absorbing incident electromagnetic radiation;
• and
• (I.a2) into the part of the liquid layer located on the workpiece, wherein when the manipulation medium is applied at least into the part of the liquid layer, the manipulation medium is configured for at least one of displacing a portion of the liquid layer in relation to the workpiece and at least partially absorbing incident electromagnetic radiation, or
• (I.a3) at least onto a part of the workpiece, wherein when the manipulation medium is applied at least onto the part of the workpiece, the manipulation medium is configured for at least one of displacing a portion of the liquid layer in relation to the workpiece and at least partially absorbing incident electromagnetic radiation, or
• I.b. onto a part of the workpiece, wherein when the manipulation medium is applied at least onto the part of the workpiece the manipulation medium functions as placeholder so that regions of the surface of the workpiece do not come in contact to the liquid layer;
• II. curing at least one of the liquid layer and the manipulation medium by the electromagnetic radiation at least until a partial curing resulting in a partially cured structure comprising at least one of the partially cured liquid layer and the partially cured manipulation medium;
• III. removal of parts of the partially cured structure to create at least one of a remaining partially cured liquid layer and a remaining manipulation medium, wherein the removal takes place in at least one of a mechanical manner and a contactless manner, wherein the removal includes a heating of at least one of the partially cured structure and the manipulation medium after the curing by supplying heat for at least partial liquefaction of the parts;
• and—curing at least one of the remaining partially cured liquid layer and the remaining manipulation medium after the removal until a final curing.
