Abstract (en)
[origin: WO2013074105A1] The present invention relates to laser marking articles. In particular it relates to laser marking articles by laser ablating a coating applied to the article which reveals the surface of the article underneath, thereby forming the mark by the contrasting appearance between the revealed surface of the article and the adjacent remaining coating. Laser parameters are selected to provide uniform, commercially desirable appearance and avoid damage to the underlying surface while maintaining acceptable system throughput. In particular the laser pulse envelope is tailored to provide desirable appearance while maintaining acceptable system throughput.
