Abstract (en)
[origin: WO2009100784A1] A method (1) for providing matrices (2) for embossing polymeric films (3) and the like, particularly for imprinting microscopic identification strings and images (4), consisting of the following steps: A) providing a uniform background diffraction grating (5) on a flat plate (6) by means of a standard holographic technique; B) subjecting the flat plate (6) to at least one pulsed and localized energy beam by means of a procedure comprised among ablation, vaporization and melting of portion of material that constitutes the plate (6) in the neighborhood of the at least one point of incidence of the beam; C) repeating the exposure (B) to pulsed and localized energy beams according to a sequence of consecutive dots arranged in the configuration of the image of the element to be imprinted (4).
