Abstract

L'invention concerne un dispositif d'impression qui, sans qu'une commande avancée soit nécessaire, empêche une impression incomplète en empêchant de l'encre qui a été transférée sur des objets cibles d'entrer en contact avec un élément de transfert, qui maintient la qualité d'impression même lorsque le traitement est accéléré et qui permet d'obtenir un rendement de production élevé. La présente invention comprend : un élément de transfert (150) qui présente sur sa surface une région d'image (151) au niveau de laquelle une image est formée ; une pluralité de mandrins (120) qui transportent des objets cibles cylindriques et qui sont capables de tourner ; et une unité de transport (130) qui déplace les mandrins (120) le long d'une voie de transport. L'élément de transfert (150) présente une région de prévention de réadhérence (152) qui supprime l'adhérence d'une image qui a été transférée sur une surface circonférentielle externe d'une partie de corps des objets cibles.
