Abstract

The invention relates to a data carrier, especially a value document or security paper, having a substrate (20) and, applied on the substrate, a coating (12) into which, through the action of laser radiation, markings (14) are introduced in the form of patterns, letters, numbers or images. According to the present invention, it is provided that the coating (12) includes a laser-radiation-absorbing layer (22) and a printing layer (24) that is disposed over the absorbing layer and that is at least partially transmissive to the laser radiation, and that the printed substrate is pressed (26) during or after the imprinting of the at least partially transmissive layer (24).
