摘要：
The invention relates to a method for the laser marking of a support having a body and a cover sheet. A laser beam is used to etch the body of the support through the thickness of the cover sheet. The support is laminated either during or after the laser marking in order to reduce or prevent deformations in the cover sheet resulting from etching.
