摘要： A method of preparing a die form comprises the steps of: (i) providing a die form body 1, having an upper surface comprising an arrangement of elevations 2 and depressions 3 defining a pattern; (ii) applying a soluble material 5 to the upper surface such that said soluble material 5 is received in the depressions 3; (iii) applying a film material 7 to the upper surface of the die form body to cover the upper surface of the die form body 1, coating the elevations 2 and the soluble material 5 in the depressions 3; and (iv) removing the soluble material 5 by exposure to a solvent; wherein removal of the soluble material 5 using the solvent causes the removal of the film material 7 from the die form body 1 in regions corresponding to the depressions 3, and not in regions corresponding to the elevations 2, the film material 7 thereby forming a mask in accordance with the pattern. A method of applying a pattern using a die form including a mask and curable materials is also disclosed

摘要： A method of manufacturing at least part of a security device is disclosed. The method comprises: conveying a substrate web comprising a photosensitive film along a transport path, the photosensitive film being adapted to exhibit an increase in optical density upon exposure to radiation of a predetermined wavelength and concurrent or subsequent heating, the increase in optical density being due to the formation of bubbles within the photosensitive film; exposing the photosensitive film to radiation of the predetermined wavelength through a mask, wherein the mask comprises a predetermined pattern of regions which are substantially opaque to radiation of the predetermined wavelength and at least semi-transparent to radiation of the predetermined wavelength, respectively; during the exposure, moving the mask alongside the substrate web along at least a portion of the transport path at substantially the same speed as the substrate web, such that there is substantially no relative movement between the mask and the substrate web; and heating the substrate web comprising the exposed photosensitive film. In this way, regions of the photosensitive film exposed to the radiation of the predetermined wavelength undergo an increase in optical density such that the photosensitive film displays a reproduction of the predetermined pattern. Security devices are also disclosed.

摘要： The present invention relates to a method for forming a surface relief microstructure, especially an optically variable image (an optically variable device) on a paper substrate comprising the steps of: A) applying a curable composition (varnish) to at least a portion of the frontside of the paper substrate; B) contacting at least a portion of the curable composition with surface relief microstructure, especially optically variable image forming means; C) curing the composition by using at least one UV lamp which is arranged on the backside of the paper substrate; D) optionally depositing a layer of a transparent high refractive index material and/or a metallic layer on at least a portion of the cured composition, wherein the lamp having emission peak(s) in the UV-A and near VIS range range and the curable composition comprises at least a photoinitiator which absorbs in the UV-A region and preferrably in the near VIS range, a paper product obtainable using the method and an apparatus for forming a surface relief microstructure on a paper substrate. Surface relief microstructures, such as holograms may be replicated rapidly and with accuracy on a paper substrate by using the method and the apparatus of the present invention.
