摘要： There is described the use of a transparent film comprising a non-fibrous substrate layer of regenerated cellulose in the manufacture of a security article exhibiting printed information, wherein said transparent film is the material on which printed information and optionally one or more other security feature(s) is disposed, and wherein said transparent film exhibits one or more, and preferably all, of the following properties: haze of no more than 10%, preferably no more than 5%, preferably no more than 4%, preferably no more than 2.5%; birefringence of from about 400 to about 800 nm; a surface energy of at least about 38 dynes, preferably at least about 40 dynes, preferably at least about 42 dynes, and preferably no more than from about 60 dynes; and a water vapour permeability in the range of from about 20 to about 40, preferably from about 25 to about 35, preferably from about 28 to about 32 g/m2/24 hours at 25° C. and 75% relative humidity, and/or in the range of from about 110 to about 130, preferably from about 115 to about 125, preferably from about 118 to about 122 g/m2/24 hours at 38° C. and 90% relative humidity.

摘要： There is described a method of manufacturing a security article, said method comprising the steps of: introducing into an offset printing device a transparent film comprising a non-fibrous substrate layer of regenerated cellulose; disposing an opacification layer on at least a portion of at least one surface of said film by a first offset printing step; and disposing printed information on at least a portion of said opacification layer by a second offset printing step.

摘要： An inking system for inking an intaglio printing cylinder of an intaglio printing press is designed to perform a selective transfer of ink to one or more intaglio printing mediums by way of a selective inking cylinder provided in at least one device. The selective inking cylinder carries a selective inking plate that receives ink supplied by an associated inking unit. The selective inking plate comprises a coating that is selectively structured to exhibit ink-repellent portions and perform selective transfer of ink at locations corresponding to engraved areas of the one or more intaglio printing mediums that are to be inked with the ink supplied by the associated inking unit. The selective transfer of ink is performed indirectly from the selective inking cylinder to the one or more intaglio printing mediums via an ink collecting cylinder and/or via a chablon cylinder carrying a chablon plate.

摘要： There is described a method of manufacturing a security article, said method comprising the steps of: introducing into a printing device a discrete sheet of transparent film comprising a non-fibrous substrate layer of regenerated cellulose; disposing an opacification layer on at least a portion of at least one surface of said film by a first printing step; and disposing printed information on at least a portion of said opacification layer by a second printing step wherein said second printing step is an offset printing step.

摘要： There is described a security element (EL) or document (BN), such as a banknote, comprising (i) a substrate (S) with first and second sides (I, II) and exhibiting at least one window region (W) made of a substantially transparent material, (ii) a micro-optical structure (OP) provided on the first side (I) of the substrate (S) and extending over at least a part of the window region (W), and (iii) a printed feature (P1-P3) printed on the second side (II) of the substrate (S) over at least a part of the window region (W), the printed feature (P1-P3) being provided in register with the micro-optical structure (OP) to produce an optically-variable effect (EF) upon looking at the printed feature (P1-P3) from the first side (I) of the substrate (S) through the micro-optical structure (OP) and the window region (W). The security element (EL) or document (BN) further comprises a protective layer (L) acting as printable primer layer and provided on the second side (II) of the substrate (S) over the window region (W) and on top of the printed feature (P1-P3), which protective layer (L) covers the printed feature (P1-P3) when seen from the second side (II) of the substrate (S) and further acts as a contrast-enhancing layer for the optically-variable effect (EF).
