Abstract

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.
