Embodiment Construction

[0032] Embedding security elements into packaging materials during papermaking requires spacers containing multiple diffractive structures on the embedding surface. Diffractive structure spacers are elements capable of embedding diffractive structures in desired materials, such as paper or cardboard or packaging material webs. The diffractive structured spacer is preferably arranged in a matrix suitably distributed on an embedded surface, such as a roll in a paper machine or printing unit as described below. Because the desired diffractive structure of the spacer matrix is ​​first obtained by electron beam, laser beam, X-ray beam, ion beam, or obtained by coating a suitable resist on a suitable substrate by other lithographic methods. This microscopic surface relief profile is formed on the resist protection layer. After this, the surface is converted to a negative surface profile in nickel by electroplating. This creates secondary and tertiary power generating pads for a la...

Abstract

A security paper or board product carrying micro or nano structures such as diffractive optical elements is formed in which the diffractive structures are integrated into the security paper or board product in the manufacturing process. A security package carrying diffractive structures is manufactured wherein diffractive structures are integrated into the security package at a manufacturing stage of the security package material. A security package contains authentication information in the form of diffractive structures. The diffractive structures are included in the security package in at least in one of the following forms: as embossed in the package material, as part of the size or paste or resin used in the manufacturing process of the security package, or as part of the ink used in printing the security package or the security package material.

Description

technical field [0001] The present invention relates to a method for producing security paper or paperboard products or security packaging with micro or nano structures for providing identification information, such as diffractive optical elements. The invention also relates to a security package which will contain identification information when forming the diffractive structure. Background technique [0002] Diffractive optical elements are optical elements that contain dimensions of natural light wavelengths. With diffractive optical elements, the propagation of light can be controlled through macroscopically smooth surfaces containing micro- or nanostructures. These structures are hereafter referred to as diffractive structures. A simple example of a diffractive optical element is a one-dimensional diffraction grating with periodic grooves constituting the natural wavelength. When a white light beam passes through or reflects off a diffraction grating, it is scattered...
