Description

Security feature, for the manufacture of method and the value document that comprises security feature and/or the secure file of security feature
Technical field
The present invention relates to a kind of security feature of value document and/or secure file, a kind of method for the manufacture of described security feature and a kind of value document that comprises described security feature and/or secure file of being identified for.
Background technology
Use value document and/or secure file diversifiedly, for example identify file---as travelling passport or identity card.The security feature used in value document and/or secure file only can for its type or with its user authenticity of confirmative document (credibility) independently.This class security element is for example that composite fibre, pearl not exactly round in shape are engraved, the dedicated paper of bank note etc.In addition, personalized (comprising personalized) security element is with coding form or expressly to comprise about file type, file user or clearly to distribute to the information of the theme of file.In the situation of distributing to a people, relate to personalized security element.This category information can be user's face-image, its personal data (as name, date of birth, birthplace), signature or person identifier (as membership number).Other security elements that make personalization of documents can be for example the sequence numbers of file.
Value document and/or secure file are printed with information and/or the pattern of the authenticity of documentary evidence usually at least in part.A kind of method of the meticulous netted line image for the manufacture of how much law weave ins that pearl not exactly round in shape is engraved, basis is determined is for example disclosed by DE1427626.Engrave in order to manufacture pearl not exactly round in shape, produce pearl not exactly round in shape with the recess form by gravure method in printing forme and engrave line.Typically by steel plate carved gravure method, form the theme on bank note.
Also use recently digital print methods shown, especially in order to customized information is introduced in file.Described a kind of polymeric layer composite construction in DE102007052947A1, it comprises the ink jet printing layer that comprises equally carbonate polymer on polymeric layer that at least one is made by the carbonate polymer based on bisphenol-A and described polymeric layer.Described polymeric layer composite construction can be for the manufacture of secure file and/or value document.
In the printing process of the printing images for the manufacture of on value document and/or secure file, stock is kept smooth as far as possible, in order to guarantee that desired printing images is transferred to stock from die or from impression cylinder or from the digital template perfection.
In order to protect value document and/or secure file; proposed multiple security feature, it can have been identified by bore hole or in the situation that just can identify by definite aid (for example, in the situation that with UV-irradiation or by magnifying glass or in by fractographic situation).Especially the Central Bank that some security features of bank note are only issued is known, thereby the adulterator does not even also know its existence.All these features for prevent original document imitation production or its forgery or at least make this become very difficult.Yet, the demand of sustainable existence to novel security feature, the security feature of described novelty is difficult to adjust, in order to make the transmission of knowledge about copying or forge required technology keep lowlyer.
Summary of the invention
Therefore, task of the present invention is to realize a kind of security feature of the novelty for value document and/or secure file.But the security feature of described novelty should be very simple and therefore cost advantageously manufacture.
Described task is by the method for the manufacture of the security feature that is identified for value document and/or secure file according to claim 1, solve by the security feature for value document and/or secure file according to claim 10 with by the value document that comprises this class security feature and/or secure file according to claim 12.The preferred embodiment of the present invention illustrates in the dependent claims.
As long as use term " security feature " in specification and claims, described term " security feature " can be understood as or is the part of value document and/or secure file and the entity that therefore can not be connected with file with breaking away from, thereby described entity is the part of file thus.Described term " security feature " can be understood as the entity (security element) separated with value document and/or secure file, and it can the time to this class file or in this class file.Security feature can be applied on film or be applied to for example, patch on secure file itself (bank note) in this case, and described film is integrated in the polymeric layer composite construction for the manufacture of value document and/or secure file subsequently.
As long as use term " embossment shape " in specification and claims, described term " embossment shape " can be understood as the surface existed with relief shape.Described surface is the surface of stock and is the surface of printed substrates in case of necessity in current situation.Associated surface characteristic is therewith, and stock or printed substrates have three-dimensional surface texture: for example stock or printed substrates can be in the situation that the smooth layout of stock or printed substrates have some protuberances and/or some recesses from basic plane.If term " embossment shape " relates to printed substrates, the recess in embossment additionally has the opening through printed substrates, or the opening that recess can be run through by this class fully forms.
As long as use term " pattern " in specification and claim, described term " pattern " can be understood as by bore hole or only for example, in the situation that use the appreciable two-dimensional structure of aid (magnifying glass or microscope).Pattern can be comprised of or the variation of the pictorial element existed that also can be by another pattern forms the pictorial element that typically no longer can differentiate by bore hole, thereby produces the overlapping of the first pattern of having existed and the second pattern.
Pattern can have any abstract form and for example by line, and------as alphanumeric (comprise special identifier---as fullstop, comma, bracket and dash) forms, or pattern can be also image---for example file holder's face-image can be maybe to determine object---as the diagram of badge as pearl not exactly round in shape is engraved, face, any combination forms or alternatively by sign.Pattern on the meaning of this understanding, can be also no dyeing or level dyeing, do not there is the face that is positioned at structure wherein or for example, through continuous dyeing, face that be provided with change color, background printing.
The method according to this invention is for the manufacture of the security feature of the novelty that is identified for value document and/or secure file.Described method is included in the printed layers of printing the first main pattern form on stock.By methods according to the present invention, during printing printed layers, forming in the situation of desirable pattern for the second time is out of shape stock embossment shape ground.Described distortion preferably only temporarily, only occur during printing process.Subsequently, preferably cancel again the distortion of stock, even stock is converted to common smooth configuration again.Method forms the distortion of embossment shape in any way.Produce desirable pattern for the second time by the distortion of embossment shape in the printed layers that forms the first main pattern.Therefore, desirable pattern covers the first main pattern for the second time.
Therefore, the security feature for value document and/or secure file according to the present invention comprises stock and is applied at least one lip-deep first main pattern of stock by printing process, and the described first main pattern is formed by printed layers.The embossment shape distortion that printed layers is carried out during printing process by stock changes, thereby the first main pattern is because the embossment shape is out of shape with desirable pattern is overlapping for the second time.Desirable pattern may be visible by bore hole in the first main pattern for the second time.But the change that printed layers causes in the embossment shape during printing process distortion due to stock may be only at the aid by additional---just can identify in as magnifying glass or microscopical situation.
According to security feature of the present invention preferably by the manufacturing method according to the invention manufacture.
By methods according to the present invention, value document and/or secure file comprise the security feature that at least one is so manufactured.
In order to produce the second pattern that covers the first pattern, form the embossment shape distortion of the second pattern form, and the printed layers of the first pattern form is pressed onto on the stock of distortion like this.
In order to form desirable pattern hypothesis following (following consideration does not have restricted impact to the protection domain of claimed invention) for the second time:
In method of contact printing---as in offset printing method or method for printing screen, impression cylinder or for the extruding force of the die of serigraphy the local surfaces changing features according to the embossment shape distortion of stock: because in the scope of surperficial flat site and especially in the scope of the protuberance on surface, extruding force is than larger in the scope of recess.For example, in hectographic printing, the rubberized fabric of impression cylinder is in the more seriously compression and therefore in the scope of flat site and protuberance, produce larger extruding force in the scope of flat site and recess of the scope internal ratio of protuberance.Thus, according to the extruding force on the surface that acts locally on stock, by different methods, printing-ink is applied on stock and in case of necessity and is applied in stock.If stock for example relates to paper, can suppose: printing-ink is during in the position with local extruding force increased, than having, more weak the extruding force increased or the position that even has the extruding force weakened are invaded (being pressed into) paper material more strongly.Obtain thus the colored shadow of the variation of corresponding surf zone.Likely, color separated applies corresponding printing position relevant from the local extruding force worked and on stock with (therefore) color and locates different.Estimation also can be supposed corresponding effect in the situation that be different from the stock of paper.For example can suppose: printing-ink is at plastic sheeting---for example on the surface of polycarbonate film, in the position of the extruding force with increase, be extruded into the adjacent position with less extruding force.For example in aniline printing or in serigraphy, also it is contemplated that such situation, because in these cases than the thicker printed layers of application in offset printing method.
Be for example in the situation of ink jet printing method of dot matrix printing process one by one in the off-contact printing method,---be different from method of contact printing ground---on the contrary and certainly do not depend on the extruding force of variation.And can suppose in this case: the ink jet printing nozzle changed due to the topology of stock of distortion and the spacing on stock surface and especially between the local surfaces element (at its place, ink droplet occurring) of ink droplet path and stock the angle of variation cause different printing images.For example by traditional methods, vertically appear at the conglobate printing points of lip-deep ink droplet shape of stock, and to be different from traditional methods---appear at lip-deep ink droplet and form different with circle, microscler printing points shape for example being not equal under the angle of 90 °.In addition, in the method according to the invention, printing points is easy to extend with being interlaced with one another.In traditional off-contact printing method, printing points arranges abreast each other and keeps separated from one another, does not at least impel in the horizontal printer's ink in the stock material during excess diffusion when stock.Spacing between print nozzles and stock surface affects the shape of printing points in mentioned methods with changing.
If in the situation that the printing images of application method of contact printing the first pattern is dot matrix, the printing images of the first pattern resolves into single printing points (printing element) in described situation, as the second pattern produced by the distortion of the embossment shape by stock, the modification of the first pattern is to the distortion of each printing points in non-contact method, because the change of the shape of the printing points of the first pattern is caused by the embossment shape distortion of stock in described situation, for example because in offset printing method in this described situation impression cylinder sentence different angles in each printing points and be pressed onto on stock.Especially in this described situation, printing points is extended with being interlaced with one another, and this is not this situation in the traditional printing method.
When in hectographic printing, not with the form of printing points but with the form of line or face, producing printing images, it is applicable that free burial ground for the destitute is also had a mind in above explanation certainly.
The overlapping of the first pattern and the second pattern may not be appreciable by bore hole, thus the failure because the adulterator ignores described security feature of adjustment for copying or forging.In no case may realize adjusting by traditional printing process because the shape of the printing images produced by described method with in the situation that application the method according to this invention structure is different, thereby obtain security feature novel and anti-imitation.Can regard printable " watermark " as according to security feature of the present invention, because it may the form with the second pattern in the first pattern present with the form of " impression ".
For example can produce the structure in color layers, for example people's face-image or other themes, color background printing or the printing of polychrome background, semi-tone printing, rainbow printing or pearl not exactly round in shape are engraved the structure in printing.The structure example of the second pattern as can be engraved by line, especially pearl not exactly round in shape, symbol, alphanumeric sign, badge diagram etc. form and only with testifying feature or also as the feature of personalized (comprising individualized).For example can form the second pattern with the sequence number of file or the form of value explanation.
According to the present invention, produce the printed layers of the first pattern form by printing process arbitrarily by traditional methods.Described printing process can be method of contact printing---the combination of especially protruding seal method, gravure method, lithographic plate printing method, print through method or these methods, or off-contact printing method ink jet printing method for example one by one.In the situation of method of contact printing, method for printing screen is particularly preferred with scraping method.Also can use offset printing method, aniline printing method and laser printing method.Printing process can be rotary process.According to the present invention, by described method, can or consume printing-ink or printer's ink or paint.
Stock for the manufacture of security feature can be film or paper, or it can comprise thin-film material and/or paper material.Stock can or alternatively exist with roll form with the page form.Basically, all polymer raw materials common in the field of value document and/or secure file can be as the raw material of stock.Polymer raw materials can be based in following group polymer raw materials structure in the same manner or differently: described group of copolymer formation that comprises Merlon (PC), especially bisphenol-a polycarbonate, PETG (PET), polymethyl methacrylate (PMMA), TPUE (TPU), polyethylene (PE), polypropylene (PP), polyimides (PI), trans-polyisoprene, polyvinyl chloride (PVC) and this base polymer.Stock can be formed or be comprised these polymer by these polymer.Alternatively, stock also can be made or be comprised these materials by paper, cardboard or textile.Alternatively, stock also can consist of or comprise them or be made by the single complex formed of these materials the mixture of mentioned material.The part of stock or stock can be transparent or translucent (transluzent or semitransparent) or opaque.At least one transparent or translucent (transluzent or semitransparent) window also can be arranged in opaque file in addition.According to security feature of the present invention, can in the file level of value document and/or secure file or on file level, form, described file level means inner file level or outside file level in the file completed.
Value document and/or secure file can be: identity card, travelling passport, ID card, access card, visa, admission ticket, driving license, driver's trip ticket, marketable securities, credit card, chip card, bank note etc.
Cover the second pattern according to embossment shape according to the present invention, being out of shape and producing by stock during the printing process for the first pattern of the first pattern.Described distortion preferably produces by the embossment shape surface texture of smooth (or to be suitable for this layout, alternatively, arch) printed substrates, when printing, on described printed substrates, places and preferred fixing stock.Stock especially can be by the recess in the surface of printed substrates and/or the distortion of protuberance embossment shape ground.During printing process, printed substrates for example can be placed on print station.
Printed substrates is embossment shape ground structure and therefore have some recesses and/or some protuberances in this case.When printing, stock completely or partially is touching on the embossment structure on surface of printed substrates.For example, by process for stamping (protruding pressure, recessed pressure) or pass through engraving method---for example method for chemially etching is manufactured embossment structure.Printed substrates especially can be by metal---for example stainless steel make but may be also can be by other materials---for example be made of plastics.
In addition, the embossment structure of printed substrates can be variable, for example, in order to by the second pattern, customized information is introduced in value document and/or secure file.This class customized information can be with for example bar code or form expressly, introduce and can be for example passport number or other sequence numbers, file holder---passport holder's name for example.With personalization, for example can use the structure of the segmentation of printed substrates for the changeable embossment structure that obtains printed substrates, it for example, by holding up each segmentation (beam or pin) in substrate or realizing by changing stereotype in substrate.
In order to realize by the embossment shape surface texture of printed substrates the embossment shape distortion of stock, in a kind of preferred embodiment of the present invention, can during printing, stock be sucked to recess.
For this reason, the opening run through in printed substrates---the opening of for example hole, the line of rabbet joint or other shapings can be positioned at the scope of recess, or the opening that recess is run through by this class fully forms, thereby stock can be sucked in recess by the low pressure obtained by opening.If recess is comprised of the opening run through fully, recess has desired layout for the second pattern forms, and that is to say, it has cross section circle, foursquare, rectangle or that method is shaped by other means, for example sign format.In case of necessity, a recess also can hold a plurality of openings.Therefore, stock can pass through these openings---and for example the perforation in printed substrates or punching suck in recess.
In that substitute at the another kind of the present invention or preferred embodiment as the additional application of the above embodiment, printed substrates can be porous, especially micropore, and the low pressure obtained by the porous by printed substrates is drawn onto stock on the surface of printed substrates and for example sucks in recess.Due to the porous of printed substrates, on the face of substrate, the low pressure of effect is applied on the bottom side of stock equably.Therefore, in the scope of the recess in the surface of printed substrates, stock can be drawn onto in the recess in the surface of described printed substrates.In addition, stock is responsible for the fixing of the plane of stock during printing process by the porous even absorption of printed substrates.If if printed substrates additionally comprises the opening run through in the recess scope or the recess in printing stencil additionally with the formal construction of the opening that runs through as shown in previous except porous, can produce low pressure targetedly in the recess scope in addition, thereby the stock in these scopes has the shape of recess reliably.
In addition advantageously, at printing process heating stock, in order to improve its deformability.For example, the stock of being made by Merlon when heating better by the embossment structure that contacts substrate on, in order to accept embossment structure.For this reason, can heated substrate.
If also be arranged in the surface of printed substrates with male part except recess in mentioned situation, stock not only has the shape of recess fixedly the time on printed substrates---for example be inhaled in recess but also automatically be matched with the corresponding embossment structure of printed substrates and also stand the corresponding embossment shape distortion of protuberance form at this point.
Protuberance can be outstanding pin or the beam from the surface of printed substrates for example.
In method of contact printing in application for the manufacture of the first pattern and the second pattern, can during printing, stock additionally be pressed onto on the surface of printed substrates.For example, in offset printing method and in method for printing screen, by impression cylinder or the die that uses in serigraphy, stock is pressed onto on printed substrates, thereby additionally can realizes that stock closely is attached on the surface of printed substrates.
In a kind of particularly preferred embodiment of the present invention, by the off-contact printing method, printed.The corresponding shaping on surface that in this case, also can be by printed substrates makes the distortion of stock embossment shape ground.For this reason, as previous explanation, can stock be drawn onto on the surface of printed substrates by low pressure.But certainly additionally from printed side, stock is not pressed onto printed substrates in this case.
The off-contact printing method can be especially ink jet printing method, wherein can use all general ink jet printing methods, especially drop on demand ink jet method (Drop On Demand-Verfahren:DOD), wherein each ink droplet is ejected on stock, perhaps can use the continuous spraying method of the use of ink and water (Continuous Ink Jet-Verfahren:CIJ), it is expelled to continuous ink-jet on stock.
Under any circumstance, by corresponding printing process in the situation that form printed layers method printing in a conventional manner the first main pattern, and the embossment shape of the form of desirable pattern for the second time by stock is out of shape to revise the printed layers of the described first main pattern form, thereby produce the second pattern with the first pattern overlapping ground.
As set forth above, the difference that produces printing images in corresponding method is revised, and it causes the overlapping of the first pattern and the second pattern.In planographic, the second pattern preferably appears in printed layers by different colored shadows, and in the situation of printing images dot matrix and especially in the printed layers produced by the off-contact printing method the second pattern with the modification of printing points shape, manifest.
