Abstract
The security paper incorporates, as fundamental characteristic, groups of security yarns which are braided within each group, using at least three yarns so that such braiding presents a very characteristic irregular surface, easily detectable by touch, for identification of the document either by the bank staff or by blind people. The use of yarns of different colours in each braid-ing allows to form colour combination which collaborate in the personalization of the yarn and, consequently of the document, for example the colours of the national flag corresponding to the country issuing the document.
Description
SECURITY PAPER FOR BANK NOTES AND OTHER DOC~MENTS
S P E C I F I C A T I O N
OBJECT OF THE lNV~.llON
The present invention relates to the structure of a new security paper, namely as used in the manufacture of bank notes and other kinds of valuable documents, within which paper are provided yarns or markings to enhance its security in the face of various modes of or attempts at counterfeiting.
R~K~uND OF ~l~n~ lNv~N~l~loN
With this aim of preventing, or at any rate impairing, the forging of a document, security paper provided inside with sheets or yarns of a suitable nature to personalize the document, and thereby enhance its security, are well-known.
More specifically, security yarns are inserted in the paper at the sheet formation stage, so that they remain in the cellulose fibres, and hence any attempt at removing the same implies either tearing the paper or breaking the yarn, which clearly reveals that the document has ~een tampered with.
Thus, in theory, the provision of a security yarn stands as security for the genuineness of a document.
However, the contemporaneous evolution of counterfeiting techniques has made it necessary to gradually perfect these security yarns, improving their performance, or to put it otherwise, hindering the tampering or copying thereof by counterfeiters. In this sense, yarns have been provided with microprinted texts, which texts can for instance refer to the country of issue, the face value of the document, the date of issue thereof, and so forth, which texts cannot be perceived at 207~00 1 first ~lance but are easi.ly cletected llsinq a small magnifylrlg glass or any other sultable means, such as viewing the same against the light~ under ultraviclet light and so on.
Techniques have also been developed whlch expedite the appearance of the yarns on the surface of the paper at regular intervals, to be detected by touch and hence identified by an expert.
Alonq these lines of evolut~on, the appiicant himself holds Spanish patent of invention application number P 8902252(1) (laid-open 20 April 1990l, which describes security paper and a method for obtaining the same, which provides for the security yarns to be obtained from an alloy of magnetic material sub~ect to heat treatment comprising a sudden cooling from a starting temperature rang~ng betweerl 800 and 1500C down to a fLnal temperature ranglng between -1~0 and -225C, there~y tc~ obtain an amorphous solld, devolcl of the usual metallic crystalline structure, so that the obtention of thls kind of security yarns by potential counterfeitQrs ls almost lmposslble.
SUMMARY OF TH~ INVENTION
The security paper subiect of the lnvention, usiog security yarns in accordance with the contents of the preceding paragrAph, stems from a llne of development contemporaneous to that of the said Spanish Patent Application 8902252, wlth the same baslc ob~ectlve but following a different route.
The inventlon provldes security paper for bank notes and other documents, of the kind having therein security yarns that can be microprlnted or- have fluorescent or iridescent ~7395-31 characteristics, essentlally characterised in that the said yarns make up groups, of at least three in number, a special feature being that the yarns in each group are related to each other by bralding, so that the "brald" thus obtained, in addition to being considerably thick, even in excess of one hundred microns, provides a hlghly characteristic surface to touch, allowing the easy detection thereof using this sense.
The new security paper attains the following features:
1~ - A personalization of not only ~he paper but also the actual multiple yarns, for the latter can bear dlfferent colours - 2a -2-~395-31 thereby to display, for instance, the colours of the flag of the country issuing the document or what other kind of personalization soever is deemed appropriate.
- The obtention of a raised portion on the document, with the typical roughnness and unevenness of a braiding, almost impossible to copy using the classical systems to provide polyester-based slivers having an evidently smooth raised surface.
- The tactile detection of various braided yarns is far easier than the detection of a normal or smooth security yarn, and the said detection is easy for bank staff, such feature also applying to the detection of documents by the blind, who will find it far easier with these braided yarns to detect, for instance, bank notes.
~K~rr~ EMBODIMENT OF THE INVENTION
Now then, in accordance with the above description, the essential characteristics of the security paper subject hereof, using the basic construction of any conventional security paper and possibly providing any other known security means or complement, lie in the fact that the likewise classical security yarns are provided to the same, making up groups of three or more units, where the yarns are moreover braided, in order to provide an overall highly characteristic surface that is easily detectable and identifiable by touch.
These braids of yarn can be obtained using any machine capable of braiding thus, paying close attention to the fact that braiding and not twisting is the issue, for instance as commonly used in obtaining laces.
Each "braid" can be made up of yarns of different colours, in order to personalize the same, regardless of the fact that the yarn can be microprinted or lacquered with fluorescent or ~07800I
iridescent material so that it is easier to view under ultraviolet light or against the light.
It is thus not only possible as aforesaid to personalize the document as a whole, but the yarn itself can also be personalized, for instance and as set forth hereinbefore, bearing the colours of the national flag of the country issuing the document, which could with reference namely to Spain, comprise two red yarns and a yellow yarn, in the event that each braid were to be made up of the minimum number of yarns, viz. three.
As the yarns form a criss-cross, in accordance with the repeatedly mentioned braiding, this security element provides a surface with a very characteristic feel, easily identifiable to control to validity of the document, both by bank staff and privately whenever the sense of sight cannot be used, this being so in particular with the blind.
Therefore, in addition to a greater optical density, as with any kind of yarn, a greater sensitivity to touch with an almost inimitable relief is obtained.
Tests to this end have shown the feasibility of inserting braids with a thickness in excess of one hundred microns in the paper, which thickness is clearly very high, without this posing any problems whatsoever when printing the document, whereas, on the other hand, this considerable thickness will determine a highly desirable tactile effect for the document.
We feel that the device has now been sufficiently described for any expert in the art to have grasped the full scope of the invention and the advantages it offers.
The materials, shape, size and layout of the elements may be altered provided that this entails no modification of the essential features of the invention.
The terms used to describe the invention herein should be taken to have a broad rather than a restrictive meaning.
