ABSTRACT:
A laser marking method comprising steps of preparing a label material consisting of a colour layer and a transparant layer, applying the label material on a marking surface of a work, illuminating the marking surface through the label material with a laser beam of a wave length transilluminating the transparent layer so as to form a mark of a certain information on the marking surface of the work and in the coloured layer of the label material, and removing the label material from the marking surface of the work to produce a recorded label. The label can be produced simultaniously with the mark on the work wherein the information shown on the label is sophisticatedly identical with the information of the mark on the work surface.
