Die Erfindung betrifft ein Verfahren zur Erzeugung eines Ornamentes (0) in einer Klarlackschicht (K). Das Ornament (0) wird durch eine selektive Mattierung der Klarlackschicht (K) mittels einer Bearbeitung der Klarlackschicht(K) durch einen Laser erzeugt. A method is for producing an ornamental design (O) in a clearcoat layer (K). The ornamental design (O) is produced by a selective matting of the clearcoat layer (K) by working the clearcoat layer (K) by a laser. The working of the clearcoat layer may be performed by a UV laser. Additionally, the working of the clearcoat layer K may be performed by electromagnetic waves at a wavelength of about 355 nm. Furthermore, the working of the clearcoat layer K may be performed by a laser operating at a frequency of about 23 500 Hz. Still further, the working of the clearcoat layer (K) may be performed by a laser operating with a pulse duration of about 2 μs. The working of the clearcoat layer (K) may be performed by a laser operating with a line spacing of about 0.03 mm.
