METHOD AND DEVICE FOR PRODUCING HOLOGRAMS AND/OR OPTICAL EFFECTS ON A LAMINAR MATERIAL

摘要

A die (3) provided with an original pattern of a hologram or corresponding to a configuration that can provide an optical effect, is used by a superimposing and pressing on a lacquer layer (1) applied on a laminar substrate (2), and the lacquer layer (1) on said laminar substrate (2) is cured. The method comprises:
- providing the die (3) as a continuous band on which the mentioned pattern is configured;
- dynamically superimposing said lacquer layer (1) applied to the laminar substrate (2) to said die (3) on a support roller (21), and
- dynamically pressing the lacquer layer (1) applied to the laminar substrate (2) against the die (3) on said support roller (21) by means of a pressure roller (22).
