Abstract

L'invention concerne un verre de protection (1) comprenant une surface de liaison à attacher à un objet qui doit être protégé au moyen d'un liant (3), la surface de liaison comprenant une zone d'impression où l'impression est réalisée, et une zone de non-impression qui est entourée par la zone d'impression et où l'impression n'est pas réalisée. Le verre de protection (1) est caractérisé en ce que la zone de non-impression de la surface de liaison ressort davantage sur le côté de l'objet à protéger que la zone d'impression.
