| 摘要 |
<p>The invention concerns a method for surface marking of a solid substrate (1) which consists, during an illuminating phase, in illuminating said substrate with a coherent monochromatic light (2), for etching said substrate into a hollowed-out surface (3). The invention is characterised in that the conditions of illumination, including its duration, are determined to limit said hollowed-out surface to a simple abrasion for the adhesion of a printing material, and illumination phase is followed by a discrete spraying phase, during which particles (6) of said printing material are accurately sprayed in into the hollowed-out surface, and whereof the deposition subsequently determines a printed element (4).</p> |
