Definitions

  • the invention relates to a document of value, a security element and a security marking which have a marking substance which absorbs in the infrared spectral range, which shows no significant absorption in the visible range and is preferably largely transparent, as well as an examination method and a device for carrying out the examination.
  • marking materials for example introduced in printing ink, markings can be produced on any objects or their packaging, which are preferably used for authenticity checking or in the field of logistics, for example for recording and tracking the flow of goods.
  • a security code is known from EP 0340 898 B1, which has two identification marks.
  • An identification mark is essentially colorless and absorbs in the near infrared part of the electromagnetic spectrum from 700 to 1500 ran. This first marking is overprinted with a second color marking, which is opaque in the visible range and does not absorb in the infrared spectral range mentioned. The marking absorbing in infrared is detected with a reader that works at 780 to 800 nm. Such readers, which work with commercially available and inexpensive silicon detectors, are now widespread and accessible to everyone.
  • the object of the present invention is therefore a possibility for marking and a method for testing objects and in particular to propose documents of value that meet further security requirements without having the disadvantages of the prior art.
  • the documents of value, security elements and security markings according to the invention are distinguished by a marking substance which has a significant absorption in the infrared spectral range from 1000 to 2500 nm.
  • the marking substance In the visible spectral range, on the other hand, the marking substance has no or only a weak intrinsic color and therefore shows no significant absorption in this part of the spectrum.
  • the marking substance also shows no significant absorption at a wavelength of or around 800 nm.
  • the marking substance has the advantage that it cannot be detected with the widespread and inexpensive silicon detectors, which operate in the range from approx. 780 to 800 nm.
  • IR absorbers In addition to organic compounds, inorganic materials are used as IR absorbers according to the present invention, which have a better stability against environmental influences. Those absorbers based on doped semiconductor materials are preferred. Metal oxides which are also distinguished by their aging resistance are particularly preferred.
  • the marking substance is preferably present in an average particle size which is less than 50 nm. As a result, visible light is hardly scattered by the particles. The marking substance is colorless or has only a very weak intrinsic color.
  • the marking substance is preferably applied to the value document in the form of an imprint.
  • the marking substance is added to a binder or a printing ink mixed with color pigments.
  • the printing ink or the binder must not have any significant absorption in the infrared range from 1000 to 2500 nm, in particular 1500 to 2000 nm.
  • the print image to be displayed with the marking substance is arbitrary and can be, for example, a logo, alphanumeric characters, a bar code or the like.
  • the process of coextrusion is particularly suitable for this in film production. It can also be used to produce foils that only contain the marking substance in certain sections or strips.
  • the marking substance is preferably not applied or applied over the entire area, but only at selected locations or along predetermined tracks. Coding can be generated through targeted recesses or interruptions in the application or application of the marking substance. Such codes can be used, for example, to reproduce batch numbers, lot sizes or product or manufacturer names.
  • Value documents in the sense of the invention are understood to mean in particular bank notes, but also other monetary documents, such as checks, shares and vouchers. Identity cards and identification documents are also counted. Such documents of value are often provided with an individual serial number.
  • the serial number is preferably displayed in addition to a visually visible representation or exclusively by means of the marking substance absorbing in the infrared.
  • the so-called non-impact printing processes are particularly suitable for this.
  • other printing methods such as offset printing, are also suitable.
  • the area of a document of value provided with the marking substance can remain free or can be combined with a visually visible marking to be explained in more detail below.
  • the area provided with the infrared absorbing marking substance remains free and this has a slight intrinsic color in the visible, it can be advantageous to color the value document in the color or the color tone of the marking substance.
  • a further advantageous possibility for camouflaging and disguising the marking can consist in that the area provided with the marking substance is additionally coated with a layer of paint or to provide a thin cover film. Such an additional covering layer must then be sufficiently transparent both at 800 nm and in the selected measuring range, which can be between 1000 and 2500 nm.
  • the document of value can have a security marking which consists of at least a first imprint, which absorbs significantly in the visible and at 800 nm and has no significant absorption peaks between 1000 and 2500 nm, and a second imprint, which is visible and at 800 nm has no significant absorption, but is significantly absorbed in the spectral range from 1000 to 2500 nm.
  • the first and the second imprint are arranged to overlap at least in regions.
  • the security marking according to the invention has the advantage that it is not accessible with the widespread and inexpensive silicon detectors operating at approx. 780 to 800 nm, since only the imprint is recognized in this spectral range, which due to its absorption in the visible can be recognized even without technical information Aid and is recognizable with the normal human eye.
  • the marking formed by the second imprint remains hidden in such a measurement since it has no significant absorption at 800 nm.
  • the second marking is only accessible in the spectral range of> 1000 nm, since only in this range is there any appreciable absorption.
  • the infrared range from 1000 to 2500 nm is of particular interest for the purposes mentioned, since it has advantages in terms of measurement technology. The range from 1500 to 2000 nm is particularly preferred.
  • the imprint absorbs in the entire spectral range.
  • Sufficient and effective absorption is also present if absorption is only carried out in a subinterval of the visible spectral range.
  • the corresponding imprint is then easily visible and recognizable to the normal human eye under normal lighting conditions and normal viewing distance.
  • the visually visible marking can also be checked mechanically using appropriate optical devices, such as scanners or photodiodes, which operate at a suitable wavelength.
  • the absorption of which is not significant if it is less than 40%, in particular less than 30% of the value which it has at the wavelength between 1000 and 2500 nm at which the infrared test is carried out.
  • Binder and colorant are the essential components of a printing ink with which the prints forming the security marking can be produced.
  • Both the first and the second imprint can form a closed surface or can be interrupted. Designs are preferred in which additional information is reproduced by the respective imprint. This can consist, for example, of a logo, a national emblem, a lettering or other alphanumeric characters or display an image.
  • the execution as a barcode, with which information can be represented in encrypted form, is particularly preferred. Execution as a two-dimensional barcode is also possible.
  • the camouflage and concealment of the second print by the first is particularly efficient when the first and the second print are printed on essentially the same area, i.e. are congruent. However, only partially overlapping arrangements are also suitable. Regardless of the order in which they are arranged and positioned relative to one another, the two imprints can have any shape. They can be symmetrical and / or asymmetrical. The contour of the two prints can be the same as well as different.
  • the ink jet method is particularly preferred since it is a contactless printing method with which, for example, non-flat and curved surfaces can also be printed without particular difficulties. It is also particularly suitable Way to create individual, changing prints, such as a serial number.
  • the security marking according to the invention can also be applied to packaging and wrappings, such as cardboard boxes and foils, or can be printed on a tag or label, a seal or a banderole and then subsequently connected to the object which is actually to be protected.
  • An embodiment is also preferred in which the security marking is generated as an intermediate carrier on a transfer belt and from there onto a belt to be protected or identified
  • the attachment of the security marking on deposit containers, such as bottles or cans, is particularly preferred, the security marking according to the invention also having the function of a token.
  • the security marking according to the invention is advantageously used wherever the authenticity of an object or document is to be checked. Their use is also advantageous in the field of logistics, since information contained in the marking can be queried when the marking is checked at different “security levels”. For example, first information may be visually visible, but coded as a barcode, while second information , which can be identical or different to the first, is only accessible when measuring in the infrared range of> 1000 nm. The second information can also be additionally coded, for example as a bar code.
  • Preferred applications of security marking for documents concern documents of value, such as checks and vouchers, admission tickets, Lottery tickets, ID documents, such as passports, company or ID cards, accompanying documents, such as delivery notes, certificates of authenticity and customs papers.
  • Printing inks that appear visually black are preferably used, which are produced by subtractive color mixing using red and yellow base colors and one or both of the aforementioned colorants.
  • 2,5-cyclohexadiene-l, 4-diylidene-bis N, N- bis (4-dibutylan ⁇ ophenyl) amm.omun ⁇ ] comes as the infrared absorber, which has no effective absorption either in the visible spectral range or at approx.

  • the marking substance absorbing in the infrared can be checked, for example, at approximately 1070 or 1550 nm. If the absorption is measured in several different spectral ranges or wavelengths, the tests can be carried out both in succession and at the same time, since they contradict each other. do not influence each other.
  • the absorption of the visually visible portion can be determined, for example, at 630 or 650 nm.
  • the visually visible, i.e. imprint absorbing in this spectral range according to the present invention is of particular importance that it also absorbs at or around 800 nm.
  • both colored, colored and black printing inks can be used. Black prints are preferred because on the one hand they are particularly widespread for marking objects and also form a particularly strong contrast on light and transparent objects. Black markings are therefore particularly noticeable.
  • a black print is also particularly suitable to hide or hide the print absorbing in the infrared.
  • the second print which absorbs essentially between 1000 and 2500 nm, to remain inconspicuous and hidden, it is necessary that it has no significant absorption in the visible spectral range.
  • Substances that are transparent and colorless are preferably used for this.
  • their concentration in the second print should be adjusted so that it has only a weak color in the visible spectral range and still leads to sufficient absorption in the infrared between 1000 and 2500 nm.
  • the marking substance or the safety marking is usually checked in reflection. If the object to which the marking is applied is sufficiently transparent in the relevant spectral range, can also be checked in transmitted light, ie in transmission.
  • the marking substance is preferably checked at approximately 1070 nm and / or at 1550 nm.
  • the appearance in the visible spectral range or perceived by measurement or measurement technology is determined almost entirely by the first imprint, while the second portion of the security marking is not perceived here.
  • the security marking according to the invention could not be realized if normal black standard printing ink was used for the visually visible print, since this usually contains carbon black, which also absorbs above 1000 nm.
  • the printing inks or dyes mentioned in EP 0340898 B1 which absorb in the visible but are not effective above 700 nm, do not lead to this either
  • the effect of the present invention that the visually visible print can also be used as camouflage or to conceal the second print even in the near infrared at approximately 800 nm.

It is checked whether the visually essentially invisible marking is present at the checked point. However, a further measurement is preferably carried out at a different wavelength. This is preferably around 800 nm or in the visible spectral range. In this way, imitations can be identified that use, for example, the IR absorbers known from the above-mentioned prior art or very broadband absorbing compounds, for example containing carbon black. The latter would be recognizable both in the measurement of the absorption between 1000 and 2500 nm and in the visible spectral range, while the real marking substance according to the invention can only be recognized in the measurement carried out between 1000 and 2500 nm.
