Definitions
- the invention relates to a security document comprising a document body in which at least two different colors are applied, at least in a region which is visible from one side surface, along an excellent direction in the region of differing concentration profiles, wherein the at least two different Colors are fluorescent colors.
- the invention further relates to a method for producing such documents and to a device for testing such security documents with regard to a feature coded therein.
- Security documents are documents that have so-called security features that make it difficult to falsify or duplicate over simple copying.
- Security documents are i.a. as personal documents, for example passports, identity cards, identity cards, as driver's licenses, but also as value documents, for example banknotes, credit cards, bank cards, vignettes, tax stamps, postage stamps, lottery tickets or other products of value printing, for example labels, packaging imprints, in particular in the field of pharmaceuticals and food etc. used.
- security documents have a variety of different security features. Particularly preferred are security documents comprising a document body which is preferably laminated from multiple layers into a monolithic composite body.
- the various layers are preferably made of plastics, but may also include other layers, such as paper, that are easier to print than plastic layers.
- EP 0 149 542 A2 discloses security documents which, as a security feature, comprise a rainbow pressure which, in one embodiment, is embodied by means of fluorescent colors.
- a security document with a validity period. This means that the security document should only be valid in a given period of time. It is customary, for example, to print an end date in an alphanumeric coding on the security document. Likewise, such a validity date may be encoded in other ways, for example in a bar code, or in an electronic chip integrated in the security document. In particular, in the case of a visual inspection carried out by humans, a check of a validity date has proven to be prone to error since different date components (day, month, year, time, etc.) must be compared in combination.
- alphanumeric codes printed on a security document are relatively easy to counterfeit in relation to other security features.
- the invention is therefore based on the technical object to provide a security document and a method for its production and a device for checking the security document, which has a relation to a forgery improved validity feature, which is preferably visually easy to check.
- the invention is based on the idea to apply at least two different fluorescent colors over a range with different concentration gradients so that a perceptible color gradient (a rainbow or an iris) results.
- a concentration ratio of the at least two different colors changes over the range along the excellent direction.
- the concentration courses and a resulting concentration ratio course are chosen so that a region of an excellent color impression, which results from color addition of the fluorescence of the at least two different colors, is perceptible.
- a color impression resulting from the color addition of the fluorescent colors can be selected.
- the at least two colors are selected to have different lifetimes.
- lifetime of a color here always refers to a stability of the color to aging, decay, transformation, dissociation, etc.
- the lifetime of a fluorescence color thus indicates that period after which the number of corresponding fluorescence upon excitation having colorant, for example molecules, dropped to 1 / e. Where e is the Euler number.
- the life span of a color can depend on different factors. In this case, in one case, the life can be given for example by the light fastness, ie by the stability to radiation. In another case, for example, the life may be given by the stability to the environment, for example, the lifetime may be limited by oxidation by atmospheric oxygen. In one In another case, the life can be given, for example, by an internal reaction.
- the concentration ratio curve is not constant, that is, the concentration ratio changes along the excellent direction depending on the location along the excellent direction, different aging of the at least two different colors results in the area giving excellent color impression and hereinafter also area excellent color impression, shifts laterally in the area over time.
- the dimensions of the area as well as the concentration courses are chosen so that after a production of the security document within a predetermined period of validity, a perceptible shift in the area of excellent color impression is perceptible.
- a security document in which at least two different colors are applied at least over an area that is visible from a side surface, which have different concentration profiles along an excellent direction in the area, so that a concentration ratio of at least two different colors over the range depending on a location changed along the excellent direction, where the two different colors are fluorescent colors.
- the concentration courses are chosen such that upon excitation of the fluorescence, a limited area producing an excellent color impression is perceptible and the at least two colors have different lifetimes, the courses of concentration and the dimensions of the area along the selected direction being selected such that producing, within a given period of validity, a perceptible displacement of the area giving the excellent color impression. A shift of an area that gives an excellent color impression can be easily perceived.
- a device for checking the validity of a security document which comprises an excitation source for exciting a fluorescence of the two different colors, wherein at least one comparison color gradient, which represents an aging state of the security document at a lapse of the predetermined validity period, characterizing information in a memory for one Compared with a perceptible upon fluorescence excitation of the two colors of the security document color gradient are stored.
- the memory may be any medium on which information characterizing a comparison color history can be stored. In contrast to an expiration date coded in alphanumeric characters, the validity period encoded in the position of the area is much more difficult to imitate or falsify.
- the at least two different colors are chosen so that when a color is added to the fluorescent colors by a human observer, a white hue is perceived.
- the excellent color impression is thus preferably a white color impression.
- a white color impression is very different from other mixed colors that appear in a color gradient. This is true regardless of the fact that people perceive a white hue differently if necessary: one perceives the white hue rotstichig and another this than blue-tinted.
- a ratio of the two color components to time changes at a position in the area to which the colors are applied.
- the ratio changes in favor of the color, which has a longer life.
- the place where a concentration ratio sets, which causes the excellent color impression thus migrates with time.
- the area of excellent color impression shifts with time.
- the area along the excellent direction over the entire extent of the document in particular parallel to a longer edge of a substantially rectangular document.
- the area in which the various colors are applied along a longitudinal direction of a substantially rectangular, card-shaped document. If the length that runs parallel to the excellent direction over which the concentration curves change as a function of the position along the excellent direction (and thus also changes a concentration ratio) is as long as possible, then a resulting shift in a given time interval is also particular large. This facilitates perception of the shift. A shift distance per unit of time is thereby greater, so that it is easier to perceive.
- the area where the at least two colors are applied may also vary in size and / or size. or orientation be chosen differently.
- an attachment along the short document side is advantageous.
- the security document in a preferred embodiment it is provided that several different color compositions are produced which contain different proportions of the at least two different colors and are applied to a roller of a printing press in adjacent areas, the ink compositions being applied to a printing plate and other rollers by further rollers this are transferred to a layer of the document body.
- a stripe-wise application in as narrow a strip as possible allows the application of the colors in concentration gradients, which change, along a direction which is parallel to a rotational axis direction of the rollers.
- the printed image produced can be any configuration known to the person skilled in the art, in particular a solid surface, a grid, a halftone image or a line structure.
- at least one of the other rollers is a Verreiberwalze, which performs an axially oscillating movement to a mixing of the adjacent applied color compositions on a lateral To achieve trituration.
- the concentration profile of the one color of the at least two colors over the area is a monotonically decreasing (increasing), preferably continuous, function.
- concentration of one color decreases monotonously (increases) along the excellent direction, preferably steadily.
- the application of the colorant compositions to the region is made such that the concentration profile of the one color over the region along the excellent direction is a linear decreasing (increasing) function. This can be achieved simply by making constant a difference in the proportions contained in the colorant compositions for colorant compositions applied adjacent to the roller.
- a color composition is applied which contains a maximum proportion of one color (minimum proportion, in particular one color at all).
- the proportion of one color decreases in equal increments.
- a life of at least one of the colors is to be selected adjusted to a predetermined validity period. More preferably, the shorter lifetime of the at least two colors is chosen to be, i. a color selected with a corresponding life, which is in the range of the order of the predetermined validity period. It is desirable that the function indicating a position of the area of excellent color impression as a function of time can be approximated by a linear function or at least not exhibit excessive deviations from a linear function in the time domain that is on the order of the validity period.
- a shorter lifetime of the two different colors is on the order of the predetermined validity period or smaller, more preferably smaller by a factor of 8 than the predetermined validity period, and most preferably about half to one Quarter of the validity period.
- Other embodiments provide that the lifetimes differ by more than an order of magnitude and, in particular, one of the at least two colors has a lifetime that tends towards infinity.
- the absolute ratios of the at least two colors relative to one another allow a position along the distinguished direction in FIG Area where the area of excellent color impression is perceived at the time of making the security document.
- the absolute ratios are chosen so that the range along the excellent direction through the area of excellent color impression is divided into two subregions along the excellent direction, of which the larger area occupies preferably 66% to 90%, most preferably about 80% of the total extent of the area along the excellent direction.
- the concentration profiles are preferably designed such that with onset of aging of the at least two different colors, the region of excellent color impression in the region shifts so that the initially larger subregion becomes smaller.
- a third color is applied over the region having a concentration profile, a behavior similar to a concentration curve of a of the two colors, and has a similar lifetime as one of the two colors.
- Such an embodiment also includes using a mixed color having a uniform life for both components of the mixed color.
- the third color is applied over the entire area in the area. It turns out that also other colors can be used.
- the third color is applied in the region which has a Concentration course, which varies along a vertical direction to the excellent direction.
- the area of excellent color impression will be more punctiform and will increase with time both along the excellent direction and perpendicular to it, i.e., in the direction of the image. as a result, move along a curved line.
- a time scale is preferably plotted along a curve, along which shifts the region causing the excellent color impression, wherein on the time scale preferably a validity limit is marked.
- the curve will be a straight line if two colors are used, whose concentration gradients are linear and opposite along the excellent direction. Only in the case that a third color is used whose concentration profile is perpendicular to the excellent color, the time scale will run along a curved curve.
- At least one comparison color gradient which results at the time of an end of the validity period, is printed with long-lasting colors next to the area on the side surface.
- a plurality of comparison color gradients with long-lasting colors may be printed next to the area that indicate different aging states of the security document.
- a control card with printed comparative color gradients is used to validate the security document such that a controller visually views it with the security document under appropriate illumination.
- the memory of the device for checking a security document is a surface printed with the at least one comparison color gradient with long-lasting colors.
- the excitation source In a development of the device according to the invention for checking the security document, provision is made for the excitation source to be controllable with respect to an excitation intensity in order to be able to adapt an intensity of the observed fluorescence to a standard intensity. Due to the fact that due to the aging of the colors, the number of existing color pigments decreases, so does one Fluorescence intensity decreases with time. Therefore, it is advantageous to be able to regulate an excitation of the fluorescence in order to be able to adjust an intensity of the resulting color gradient due to the fluorescence. Immediately after the security document has been generated, only a low level of excitation is necessary.
- a correlation between the regulated excitation intensity and the detected location of the area of the excellent color impression is preferably carried out, since there is a fixed relationship between the two. In this way, the feature is even safer against counterfeiting.
- a preferred embodiment of the invention which allows an automated verification of the security document, provides that a document holder is coupled to the excitation source and a detection unit that detects the fluorescence, and coupled to the detection unit, an evaluation unit that, a position of the area excellent color impression and comparing the detected position with a validity period limit position indicating a predetermined position of the area of excellent color impression at the end of a validity period of the security document, and an output unit outputting a result of the comparison.
- Such an embodiment of the invention is able to check, for example program-controlled, a security document arranged in the document recording with regard to expiration of a validity period.
- the information stored in the memory that characterizes the comparison color progression is used, which includes, for example, the validity period limit position.

- a region 9 is perceptible which causes a white color impression, ie, an excellent color impression.
- the color pigments of the color cyan are shorter-lived than those of the color red, ie have a short life, then disintegrate more cyan color pigments per unit time than red color pigments.
- a location where the number of cyan and red pigments is the same thus shifts counter to the excellent direction 3, ie, to the left in the illustration of FIG.
- FIG. 3 a printing machine is shown schematically, with the aid of a security document of FIG. 2 can be produced.
- a roller (ductor) 22 for ink absorption is divided by several color separators 23, or chunks, divided in the example shown in four equal zones 24 in the axial direction. In each of the zones 24, the roller 22 is fed one of four different color compositions.
- the ink compositions supplied to the roller 22 are transferred to a printing plate 26 by further rollers comprising ink rollers 25, 25 "and at least one impeller roller 25 'and printed thereon on a layer 27 which is preferably laminated to a security document or already laminated
- the at least one distributor roller 25 * performs an oscillatory movement along the longitudinal axis 28 in addition to a rotational movement about a longitudinal axis 28. This results in a continuously adjustable lateral trimming of the color compositions, so that along the excellent direction 3 on the layer 27 monotonous, form continuous and preferably linear concentration gradients of the two different colors that make up the color compositions.
- Red and cyan are plotted against the excellent direction 3, which would result if no lateral trimming took place. It is assumed that the four color compositions consist of cyan, two parts cyan and one part red, one part cyan and two parts red and only red. With the lateral trituration, the concentration curves according to FIG. 1 then result. It will be clear to the person skilled in the art that, of course, more color compositions than four can be used.
- a third Color which is also a fluorescent color

- n i ( x ) n i, o- ⁇ C)
- n 2 ( X ) n 2,0 - ( 1 - ⁇ ) ( 2 )
- T 1 is the life of the color 1 and ⁇ 2 the life of the color 2 or respectively their color pigments.
- the mixing ratio R (x, t) or the concentration ratio of the two colors is given as: n, (x, t)
- the parameters R 0 , ⁇ i and ⁇ 2 result from the color selection (substance selection), which are suitably adapted to the desired validity period.

- a corresponding security document 5 is shown schematically at the time of manufacture.
- the area of excellent color impression 9 is located at the position 0.8 along the excellent direction. Assuming that the color 1 is red and the color 2 is cyan, a color transition from red to white is obtained from the right margin of the security document 5 over a short distance 31. A color transition from cyan to white, however, takes place over a long distance 32nd

- the examples described are merely exemplary embodiments of the security documents. It will be apparent to those skilled in the art that the application of the inks may be on a layer which may be internal to a security document embodied as a lamination body. The prerequisite for this is that the outer layers are transparent both with regard to excitation of the fluorescence colors and fluorescence. Furthermore, a described color gradient can be combined as a security feature with other security features known to the person skilled in the art, in particular overprinted or backprinted.
- the area 7 can extend over the entire extent of the document or over a part. Because of the visual verifiability, the region 7 should extend over most of the extent of the document, preferably between 65 and 100% of the extent of the document.
- the region 7, as shown in Fig. 8a may be rectangular or also have a different geometric shape, for example, be formed as a serpentine or wavy strip, as shown in Fig. 8b.
- FIG. 9 schematically shows an apparatus for checking a security document 5 with regard to expiration of a validity period.
- the device includes a document holder 42 in which a security document 5 can be held.
- the security document 5 can be arranged so that the area in which the colors are applied is reproducibly aligned.
- the device 41 comprises an excitation source 43, which preferably emits light in the ultraviolet spectral range.
- the ultraviolet radiation excites the fluorescence of the colors applied to the security document 5.
- Adjacent to the document receptacle 42 in one embodiment, a memory 48 is arranged, which may be formed at least partially in the form of a surface 44 printed with reference color progressions of durable colors, wherein the comparative color gradients 49 represent color gradients observable at different aging times of the security document 5.
- the printed area 44 represents a storage medium which stores characteristic information of the comparison color gradients 49. These are oriented relative to the document receiver 42 so that the excellent direction of the area over which the fluorescent colors are applied is aligned parallel to the comparative color samples 49 in a security document placed in the document receiver 42. The perceptible color gradients due to fluorescence can thus be easily compared with these comparison color gradients to derive an aging state and from this a validity of the security document.
- characteristic information of the comparative color gradients can also be stored digitally in a part of the memory 48, which is coupled to an evaluation unit 46.
- the device 41 comprises a detection unit 45, which is for example a camera, CCD or the like and is capable of detecting the fluorescent light of the colors of the security document 5.
- the detection unit 45 is coupled to an evaluation unit 46 which determines a position of the area of excellent color impression and compares the position with a validity period limit position indicating a predetermined position of the area of excellent color impression at the end of a validity period of the security document 5.
- About an output unit 47 is a result of Review issued.
- the output unit 47 may take any configuration capable of conveying information.
- the output unit can also be designed with two different light sources having different colors, one of the colors being assigned a meaning "validity period not yet expired” and the other having a meaning "expired validity period”.
