Afin de fabriquer une bande de film lenticulaire imprimée, notamment une bande d'étiquettes lenticulaire, un dispositif de mise en forme de lentille (1) qui forme un système de lentilles lenticulaire sur un premier côté plat (3) d'une bande de film transparente (7) et un dispositif d'impression (9) qui imprime une image lenticulaire sur un deuxième côté plat (11) de la bande de film (7) opposé au système de lentilles lenticulaire, sont reliés en une unité mécanique (13), dans laquelle la bande de film (7) est guidée en un seul passage continu tant par le dispositif de mise en forme de lentille (1) que par le dispositif d'impression (9). Quant au dispositif d'impression (9), il s'agit de préférence d'une machine d'impression à cylindre central dont le cylindre central (25) peut être conçu comme une surface de mise en forme de lentille sur sa face circonférentielle de manière à ce que le cylindre central (25) procède en même temps à la mise en forme de lentille. Comme le dispositif de mise en forme de lentille (1) et le dispositif d'impression (9) sont reliés en une unité, la précision du repérage de la bande de film lenticulaire peut être considérablement accrue.
