    摘要： In the method for the authentication of identification marks applied on a packaging foil, the identification marks, present as a barcode, are embossed on-line by an embossing roller device on a packaging foil, are read by means of a suitable apparatus and are compared to a template for the creating of the barcode, wherein the structural elements of the bar code, created by means of the template, are transferred to a set of embossing rollers with male and female rollers associated with one another and are formed on the surface thereof. Preferably, a further code is overlaid on the barcode in a further coding step, and the result is transferred and formed as a template onto the surface of the set of embossing rollers, wherein the template is used for deciphering the read-in, embossed code.
    The embossing device for the embossing of barcode onto a packaging foil (12) according to the method has a set of embossing rollers with male rollers (P5) and female rollers (M5) associated with one another, wherein the structural elements (STP, STM) of the barcode (7BCP, 7BCM) created by means of the template are arranged on the surface thereof.
    Such a method and such a device permit the embossing of particularly secure, comprehensive and compact identification marks on cardstock-type cigarette packages (12) or on inner liners (13A, 13B).

    摘要： A method for embossing optically diffracting microstructures in a thin foil, such as used to pack at least one of the list comprising food, chocolate, chewing gum, gifts, jewellery, clothes, tobacco products, pharmaceutical products, the embossing being produced with an embossing rollers set-up comprising at least one cylindrical embossing roller and a cambered counter roller. The method comprises confining the at least one cylindrical embossing roller and the cambered counter roller in a single roller stand of relatively small outer dimensions designed to withstand a pressure for the at least one cylindrical embossing roller and the cambered counter roller; using on a surface of a first one of the at least one cylindrical embossing rollers at least one raised embossing element adapted for microstructure embossing, whereby one of the at least one raised embossing elements comprises a platform distant at a height in a range between 5 µm and 30 µm above a surrounding surface of the first cylindrical embossing roller adjacent to it, and a pattern engraved on top of the platform (5), whereby the pattern comprises the optically diffracting microstructures with periodicity of gratings in the range smaller than 30 µm that produce from a diffuse or directed source of light in the visible wavelength range diffraction images with high contrast and high luminosity in a defined observation angle; and adjusting the pressure for the at least one cylindrical embossing roller on the thin foil in a range less than 80 bar relative to a platform area of approximately 100 mm 2 .

    摘要： The embossing device for fine embossing of packaging material has a set of embossing rolls with female embossing and male embossing rolls, in each case the structural elements (ML1) of the female embossing roll (M1) and the structural elements (PL1) of the male embossing rolls (P1) being assigned to each other, and the structural elements of one of the rolls being produced independently of the structural elements of the other rolls. At least one structural element (ML1; PL1) of at least one roll (M1, P1) is provided on its bottom surface (B1) and/or surface (S1) and/or side surfaces and/or in its immediate surroundings with light- scattering elements (DM1, D1), the height (H) of which is 10 µm to 150 µm. As a result of the use of light-scattering elements with small dimensions, the contrast of the structural elements can be increased substantially, by which means the overall aesthetic image is improved considerably.
