• wherein a thickness of the layer package exhibits a variation in a range between 1 μm and 1000 μm, in particular in a range between 1 and 300 μm, in particular more than 5 μm, in particular more than 10 μm and in particular more than 20 μm and wherein the layer package defines a surface structure;
• and/or wherein
• a thickness of the layer package varies over the substrate, and in particular wherein a first package portion of the layer package at a first position has a first thickness and a second package portion of the layer package at a second position has a second thickness;
• and/or wherein the layer package includes at least one void leaving a surface of the substrate at the position of the void uncovered
• and/or wherein the layer package defining a surface structure, in particular wherein a smallest lateral dimension of the surface structure is below 254 μm, in particular below 85 μm and further in particular below 42 μm;
• in particular the layer package having a curing degree that the image is able to reach a rating of at least 2-3 in the Methylethylketone- test after 10 s according to the DIN EN 12720 and/or the image resists at least 50 Isopropyl alcohol double rubs and/or the image resists at least 5 acetone double rubs, in particular at least 10 acetone double rubs, in particular at least 20 acetone double rubs;
• and/or wherein
• the layer package comprising a minimum arithmetic average roughness of larger or equal than 1 μm, Ra ≥1 μm, in particular larger or equal than 3 μm, Ra ≥3 μm, and further in particular larger or equal than 5 μm, Ra ≥5 μm;
• and/or

Method comprising:

• providing a layer package to a target surface, the layer package defining a surface structure and a thickness of the layer package, the layer package comprising at least one layer;
• the surface structure being defined by a thickness variation of the layer package;
• and
• the thickness variation being in a range between 1 μm and 1000 μm, in particular in a range between 1 and 300 μm, in particular more than 5 μm, in particular more than 10 μm and in particular more than 20 μm;
• wherein providing the layer package includes printing a coating material so as to form a coating layer, the coating layer forming a layer of the layer package, and the coating material being curable and comprising a resin, the coating material comprising an amorphous resin portion in an amount of at least 30 w-% based on the overall amount of resin, and the coating material comprising with respect to the entire amount of coating material less than 0.5 w-% of flow additive, and the printing being performed by using a non-impact printing method, in particular an electrophotographic printing method.
