The present invention discloses an improved method for transferring an image (40) onto an object (10) which has a surface that curves I two directions. After providing a source (50) containing an image (40) capable of thermal transfer, a target surface (20) is chosen on the object (10) and a chemical coating (340) is applied. The image (40) is then pressed onto the coated target surface (20) until the target surface (20) is substantially flat and heated so that the image (40) is transferred to the target surface (20). The coating (340) allows the image (40) to be transferred at a low temperature. In a preferred embodiment, after the source (50) is removed, a second application of heat is applied to the object (10) to drive the image (40) into the object (10). A protective material (120) may be positioned between the heating element (160) and the image (40), especially before the second application of heat.

L'invention concerne un procédé amélioré permettant le transfert d'une image (40) sur un objet (10) présentant une surface incurvée dans deux directions. Ce procédé consiste à prendre d'abord une source (50) contenant une image (40) pouvant être transférée par un procédé thermique, à choisir une surface cible (20) sur l'objet (10), et à appliquer un revêtement chimique (340). L'étape suivante consiste à presser l'image (40) sur la surface (20) cible recouverte de ce revêtement jusqu'à ce que la surface cible (20) soit sensiblement plane et chauffée, de manière à transférer l'image (40) sur la surface cible (20). Le revêtement (340) permet de transférer l'image à basse température. Dans un mode de mise en oeuvre préféré, on procède à une seconde application de chaleur sur l'objet (10) après le retrait de la source (50), de manière à faire pénétrer l'image (40) dans l'objet (10). Un matériau protecteur (120) peut être intercalé entre l'élément (160) chauffant et l'image (40), en particulier avant la seconde application de chaleur.
