  • This allows a wide variety of substrates, as well as functional packaging, e.g. provided with jewelry effects, wherein a sheet-fed rotary printing machine used and the film coating is carried out in the cold foil stamping process.
  • the printability of the areas coated by the film application is thereby improved by increasing the surface tension.
  • the coated printing sheet is exposed to a corona discharge or a discharge plasma. After that can be printed with high quality.

Abstract

La présente invention concerne un mécanisme de revêtement (2) permettant de transférer des couches qui forment une image ou qui assurent un recouvrement à partir d'un film de transfert (5) sur une matière à imprimer. L'objectif de la présente invention est de pouvoir utiliser un tel mécanisme de revêtement de manière flexible afin d'assurer une production intégrée de matières à imprimer complexes. On doit notamment pouvoir surimprimer sans problème des films de revêtement. A cette fin, un ou plusieurs systèmes de décharge (E, E1) reliés à un module d'application de film (FA) sont utilisés pour modifier la tension de surface du film de transfert (5) ou de la feuille d'impression dans une rotative à feuilles, de manière à permettre également une impression de haute qualité de la surface de la feuille d'impression revêtue d'un film.
