Estimating the term…
A tape data carrier for protecting articles and documents from counterfeiting and copying is formed by a polymer structure including at least one polymer layer of which at least one layer has at least one of through-perforations and pits. These through-perforations and pits are preferably between 0.001 μm and 20 μm in size and can be filled with different materials. The data carriers can carry concealed and visible macro-and micro- images created by heavy-ion bombardment of the polymer film, subsequent exposure of the bombarded film to ultraviolet radiation, and etching of the polymer film in a solvent. A device for manufacturing a data carrier of this type includes the following elements configured in series: a heavy ion source; a heavy ion beam-formation system; an ion guide; a three-dimensional amplitude modulation unit; and a target which is destined to become the data carrier. The three-dimensional amplitude modulation unit is designed to hold a matrix of wafers and is connected to a drive for rotating and translating the wafers. The drive is connected via a control unit to the three-dimensional amplitude modulation unit for positioning the target.
An information carrier being a film structure comprising at least one layer of a polymer material having a relief surface, wherein the relief surface is formed by at least one of recesses and through-holes having a form of solids of revolution and wherein the film structure comprises several layers made of polymer materials having different spectral characteristics.
A method for producing an information film carrier to protect articles and documents from counterfeiting and copying, said method comprising a step of forming marks on a polymer film having at least one layer, wherein said marks are formed by irradiating said polymer film with heavy ions to form a first concealed image, thereafter exposing said film to an ultraviolet radiation to form a second concealed image, and etching said film to create said marks in the form of recesses and holes.
An apparatus for producing information carriers, said apparatus comprising:
An information carrier being a film structure comprising at least one layer of a polymer material having a relief surface, wherein the relief surface is formed by at least one of recesses and through-holes having a form of solids of revolution and wherein the film structure comprises several layers made of polymer materials having different refraction coefficients.
