Abstract
A method for producing a decorative surface having different gloss levels preferably comprising the following steps: (C) feeding of a workpiece (1.0), which is coated with at least a first lacquer layer (1.4) to a digital printing station; (D) provision of digital control data for the digital printing station; (E) digital spraying of droplets on partial areas of the first lacquer layer (1.4) on the workpiece (1.0) with an at least partially transparent lacquer in order to apply a second lacquer layer (1.5) on the first lacquer layer (1.4), wherein after curing the second lacquer layer (1.5) has a different gloss level than the first lacquer layer (1.4). Further disclosed is an apparatus for carrying out this method.

A method for producing a decorative surface having different gloss levels comprising the following steps:
- (A) feeding of a workpiece (1.0) to a lacquer application device;
- (B) coating the workpiece (1.0) with at least a first lacquer layer (1.4);
- (C) feeding of the workpiece (1.0), which is coated with at least the first lacquer layer (1.4) to a digital printing station;
- (D) provision of digital control data for the digital printing station;
- (E) digital spraying of droplets on partial areas of the first lacquer layer (1.4) on the workpiece (1.0) with an at least partially transparent lacquer in order to apply a second lacquer layer (1.5) on part of the first lacquer layer (1.4) and not entirely on the lacquer layer (1.4), wherein after curing the second lacquer layer (1.5) has a different gloss level than the first lacquer layer (1.4);
- wherein the workpiece (1.0) is a printed workpiece printed with a decorative image before method step (A);
- wherein:
- (i) the workpiece (1.0) is a printed workpiece printed with a decorative image before method step (A);
- or
- (ii) the method further comprises printing the workpiece (1.0) with a decorative image after method step (A) and before method step (B);
- wherein the method further comprises using digital print data available for the decorative image on the workpiece (1.0) as a basis for the digital control data provided in step (D);
- wherein the digital print data is used as a basis for the digital control data provided in step (D) either:
- (i) in identical form, or
- (ii) in a form modified by a digital manipulation.
