1. A method for producing a three-dimensional structure on a surface of a flat substrate, comprising the following steps:
providing the substrate with the surface ready to be treated;
applying a relief product in the form of droplets on the surface by digital printing, such that selected areas of droplets are produced on the surface;
applying a covering product to the surface such that it forms a layer over the surface;
fixing the layer of the covering product with the selected areas on the surface being free from the covering product, thereby obtaining a three-dimensional structure on the substrate;
wherein the relief product comprises properties which provide a delaying effect in the drying such that the drying time of the relief product is greater than that of the covering product, wherein the covering product experiences a first change comprising one of drying or curing before the relief product experiences a second change comprising one of drying or curing.
