  • Publication number: 20240287739
    Abstract: A method includes embossing a section of a micro-optic security thread at a predetermined pressure in an embossing die having a male half and a female half, the micro-optic security thread comprising a polymeric substrate having a first side and a second side, forming a web of a substrate in a paper making machine, wherein the web comprises a length of cellulosic material formed at a wet end of the paper making machine and maintained under tension between the wet end of the paper making machine and a dryer section of the paper making machine, forming a watermark feature in the substrate, and adhering the micro-optic security thread by positioning the embossed section such that the layer of icon elements contacts at least a portion of the web comprising the watermark feature.

  • Patent number: 10344431
    Abstract: The invention relates to a security sheet or document having enhanced watermark(s). In one exemplary embodiment, the inventive security sheet or document is a single-ply paper that is made up of a paper layer including one or more watermarks, and a micro-optic security device (e.g., a patch or thread) that at least partially covers an upper or face portion of the watermark(s). The overlying patch or thread increases the durability of the watermark(s), thereby allowing for the watermark(s) as well as reduced fiber density areas therein to be made larger, and for the reduced fiber density areas to be made thinner. In a preferred embodiment, the micro-optic security device projects synthetic image(s) that coordinate or link in with the watermark design(s). In a more preferred embodiment, the micro-optic security device offers a machine detectable/readable feature in the form of enhanced IR-brightness, especially when measured in transmission.

  • Patent number: 9708773
    Abstract: The invention generally relates to a security sheet or document having one or more enhanced watermarks. In one exemplary embodiment, the inventive security sheet or document is a single-ply paper that is made up of a paper layer including one or more watermarks, and a micro-optic security device (e.g., a patch or thread) that at least partially covers an upper or face portion of the watermark(s). The overlying patch or thread increases the durability of the watermark(s), thereby allowing for the watermark(s) as well as reduced fiber density areas therein to be made larger, and further allowing for the reduced fiber density areas to be made thinner. In a preferred embodiment, the micro-optic security device projects one or more synthetic images that coordinate or link in with the watermark design(s). In a more preferred embodiment, the micro-optic security device offers a machine detectable/readable feature in the form of enhanced IR-brightness, especially when measured in transmission.

  • Patent number: 8366879
    Abstract: A soil and/or moisture resistant secure document and a method for producing such a secure document, are provided. The inventive method preferably employs a size press or other similar device to force a soil and/or moisture resistant formulation into the pores of the substrate and to remove excess formulation from opposing surfaces thereof. Soil and/or moisture resistant formulations when applied this way instead of by way of standard coating techniques do not obscure optically variable effects generated by non-porous OVDs that may be employed on or within these secure documents. In addition, thin layers of fibers (e.g., papermaking fibers) overlying and thus embedding portions of security devices in windowed secure documents that have been rendered soil and/or moisture resistant in accordance with this invention demonstrate increased durability.
