A printing device for printing elements in sheet fond: a platen press 310 for depositing onto each sheet 10, by stamping, colored or metalized film from at least one stamping foil; a conveyor using a succession of gripper bars for moving each sheet 10 individually through the platen press 310; a blower member separates each stamping foil from each sheet as it leaves the platen press, the blower member being movable between a work position, in which it is able to operate from the transfer region in which the gripper bars 610 run to the exit of the platen press 310, and a withdrawn position, in which it keeps away from said transfer region.
