A method for forming retroreflective sheeting comprising a binder layer having a first surface with protrusions thereon and a plurality of retroreflective elements partially embedded in the surface, wherein the method comprises forming the binder layer in a first profile, embedding the retroreflective elements therein, and then activating that binder layer such that it is restored to the first profile via shape memory.
Procédé de fabrication pour revêtement rétroréfléchissant ayant une couche liante dotée d'une première surface qui comporte des protubérances, et ayant aussi une pluralité d'éléments rétroréfléchissants partiellement intégrés à la surface. Ce procédé consiste à constituer la couche liante selon un premier profil, à intégrer les éléments rétroréfléchissants dans cette couche, et à activer ladite couche de manière à lui rendre son premier profil par effet mémoire.
