Abstract

La présente invention concerne une feuille métallique (1) munie de des codes d'identification d'échelle de gris (4, 5). La feuille métallique (1) comprend un substrat (100) et une couche d'encre sensible aux photons (101) agencée au niveau d'un côté ou de deux côtés du substrat (100), la couche d'encre sensible aux photons (101) recouvrant partiellement ou complètement la surface du substrat (100). Au moins un groupe de codes d'identification d'échelle de gris (4, 5) est formé dans la couche d'encre sensible aux photons (101). La feuille métallique (1) possède une pluralité d'unités de traitement (2), et chaque groupe de codes d'identification d'échelle de gris (4, 5) correspond à une unité de traitement (2). Les codes d'identification d'échelle de gris (4, 5) constituent des images formées après l'apparition de certains matériaux actifs photoniques dans les changements de couche d'encre sensible aux photons (101), et les codes d'identification d'échelle de gris (4, 5) possèdent une surface lisse et possèdent une différence d'échelle de gris à partir d'une région périphérique. En ce qui concerne la feuille métallique (1), pendant le processus de fabrication des codes d'identification d'échelle de gris (4, 5), seul un dispositif laser de faible puissance est utilisé afin de modifier l'aspect d'un composant actif photonique dans la couche d'encre sensible aux photons (101), sans provoquer la combustion, la gravure ou la chute de l'encre sensible aux photons, de sorte que la feuille métallique (1) et un corps de couvercle (11) obtenus au moyen de la feuille métallique (1) possèdent un bel aspect lisse et esthétique et ont un bon effet de protection environnementale.
