Abstract: The film (10) has light-controlling microstructures (12) i.e. linear structures, formed in the film and provided parallel to each other. A safety feature e.g. portrait image, is formed in the microstructures. The film is transparent in a primary view angle (14). The safety feature is designed not visible when the film is viewed in a false view angle, and visible when the film is viewed in a correct view angle (22) or a range of view angles. The correct view angle or the range of view angles is obtained, in which the film is rotated around an axis perpendicular to a surface of the film. Independent claims are also included for the following: (1) a document (2) a method for producing a safety feature in a light control film.

Abstract: The present invention concerns a system for the calibration of at least one parameter of a laser engraver, the laser engraver comprising on one hand an engraving system with a focusing lens positioned at a distance of the surface of an substrate intended to be engraved and on the other hand a vision system for at least the positioning and the verification of the engraving, the vision system including a camera associated with an appropriate illumination and, wherein the engraving device of the laser is arranged in such way that the engraving device works to engrave a substrate with specific engraved layout corresponding to variation of at least one parameter and wherein the vision system is connected to a comparison device of at least one measured engraved parameter with the template value of at least one stored data in a memorization device connected to a engraving correction device.
