If the substrate surface is arranged in a different relative position to the application device, for example laterally to the latter, the fibers can be conveyed to the surface, for example by means of an air flow. In this case, it is necessary that the fibers are fixed on the substrate surface immediately upon impact. This succeeds by a sticky surface or by heating the surface so that fibers equipped with an adhesive adhere to it upon impact.
  • the formation of the color gradient structure during overlapping deposition is decisively influenced by the distance between the application device and the substrate surface.
  • the larger this distance the greater the overlapping application, i. the proportion of fibers of one type entering the color region on the substrate surface of the other fiber type in this case is greater than when the distance is smaller.
  • this spacing may be, for example, 10 to 50 mm.
  • this distance can also be greater, for example up to 200 mm or up to 300 mm, or even smaller, for example at least 5 mm.
  • overlapping scattering of the fiber types into the other color field may also be achieved by relatively moving the application device relative to the substrate surface during application in a direction perpendicular to the transition between the two color patches.
  • the application device can be moved back and forth shaking during the application process.
  • the color-gradient structure can be produced by applying the fibers in a transition area between adjacent color fields, in which different types of fibers are applied to the at least one substrate surface, not sharply delimited to the respective color field, so that a part of the fibers also on the adjacent color field arrives. If this is realized both for the fibers of the first type applied to one of the two color patches and for the fibers of the second type applied to the other of the two color patches, a very smooth transition between the two fiber types can be achieved and thus be achieved between the two colors. Of course, in principle, an application not limited to the respective color field is sufficient for one type of fiber.
