Abstract
The invention relates to a security element comprising an optically variable structure having an embossed structure. Upon tilting of the security element about an axis and thus alternate observation from a first and second observation angle range, a tilting effect arises which shows different colours or brightnesses from the two different viewing angles or at different angles of light incidence. According to the invention, the optically variable structure has at least one second embossed structure which is arranged within the first embossed structure and produces a second tilting effect in addition to the first tilting effect. In this case, the second tilting effect occurs either within the first or second observation angle range or upon the transition from the first to the second or from the second to the first observation angle range.
Description
The present invention relates to a kind of safety element that the structure of variable vision is arranged, this structure has a kind of stamping structure.Stamping structure and one are combined as with the coating that the safety element surface forms contrast, make can the seeing when first range of view angles is observed to the small part district of coating, but are being blocked when second range of view angles is observed.Therefore, when around an axis inclination safety element and thereby during from the first and second range of view angles observation objects, form a kind of gap tilt effect, it is from two different visual angles or by different different color or the brightness of angle of light demonstration.
For this reason for example by the known a kind of data medium that variable vision element is arranged of WO97/17211, it is made up of for printing image or net of lines purpose coating a kind of stamping structure and one in form.Stamping structure or coating change its structure by part here replenishes and to be, or the effect of known variable vision takes place to strengthen, or occurs another kind ofly at least can estimating the effect of identification.The element of variable vision can be estimated identification, yet based on the characteristic of its variable vision, so can not reappear by duplicator.Duplicator can only show single line of vision again, thus lose the effect of variable vision, that is lose the identifiability of different information under different direction of observations.The element of therefore this known variable vision can be used to prevent to duplicate.
By the structure of the known a kind of variable vision of WO02/20280A1, it is made up of coating and the stamping structure that is superimposed upon on the coating.The whole zone that is provided with coating and embossing printing is divided into some subregions, in these subregions or coating or impression change for whole area is unified.Other each several parts in all subregions (impression or coating) are designed to identical, that is to say that other each several parts have identical regularity in all subregions.For example when the part stamping structure is arranged in each subregion to the phase place offsetting each other, for example there is different part stamping structures by WO02/20280A1, different screen rulings or different orientations are arranged, that is to say, the part stamping structure extends each other at an angle.In addition, the part stamping structure in each subregion also can be staggered each other, and the bearing of trend of part stamping structure keeps identical in this case.
The objective of the invention is, improve known safety element and especially further improve anti-counterfeit capability.
This purpose reaches by the feature of independent claims.Of the present invention further developing is the technical theme of dependent claims.
The present invention not only comprises a kind of safety element, a kind of data medium that safety element is arranged, and comprises a kind of coining tool of making safety element.Here, data medium especially has the valency document, for example banknote, marketable securities, credit card, account card or identity card, passport, license and so on, label, seal or other elements that product safety is used.
By the present invention, the structure of described variable vision has at least a second stamping structure, and it is arranged in first stamping structure inside and also produces second gap tilt effect except first gap tilt effect.Here preferably, in first or second range of view angles of first gap tilt effect, or from first gap tilt effect first to the second range of view angles transition or from second during to the first range of view angles transition, second gap tilt effect appears.
Under first kind of selectable situation, that is when second gap tilt effect in first or second range of view angles, occurring, second stamping structure is arranged as on first stamping structure, make it can be in sight in first or second range of view angles, and always just almost can not maybe can not see in another range of view angles.Therefore observer, when he when the range of view angles that almost can not or can not see second stamping structure is therein observed by safety element of the present invention, he can only see first stamping structure.Yet this observer just additionally sees second stamping structure from another range of view angles, and he sees second gap tilt effect when around second inclination safety element being different from first.
In this respect particularly preferably, described at least a second stamping structure is made up of some second impression elements, and they always are placed on the side of the first impression element with the angle of a regulation.Therefore the second impression element stretches out from a side of the first impression element with the angle stump shape of a regulation, and causes second gap tilt effect in this side of the first impression element.Here, the second impression element is placed on first impression element side with an angle, and the angle between second of this angle and first gap tilt effect first and second gap tilt effect is consistent.
Preferably, first and second stamping structures are designed to the mesh structure, and the straight line mesh that particularly preferably is designed to constant screen ruling, its cross section especially is designed to triangle, trapezoidal, sinusoidal or semicircle, and straight line/ripple or the form of similar structures, for example burr that three-dimensional is preferably arranged in substrate.Second stamping structure might not have the cross section identical with first stamping structure.For example first stamping structure has triangular cross section, otherwise the cross section of second stamping structure is semicircular.
Under second kind of selectable situation, that is from first to the second range of view angles transition or from second second gap tilt effect is appearring during to the first range of view angles transition, by partly changing the geometry of the first impression element, described at least a second stamping structure is inserted in the first impression element.The first impression element preferably has longitudinally or the change of change, lateral width or the gradient of transverse height in this respect, and wherein the change of lateral width or gradient can be implemented in the one or both sides of impression element.If now the observer around first inclination, then in second stamping structure is in wherein zone, second gap tilt effect also occurs with safety element except that first gap tilt effect.
For example, the first impression element can be formed each other in the wedge shape arrangement and by the side of different colours by two, and second stamping structure is designed to pinnacle, upper edge, wedge top notch-cut type depression longitudinally.The side of depression has a kind of color again, and it and first color that impresses the element adjacent side form contrast.Therefore when when first axle tilts, the observer at first sees first side of the first impression element, in first side of additionally seeing depression near the end of first range of view angles, extend this parallel sided or first side that almost is parallel to the first impression element.Continuing when first axle tilts, the observer also sees second side and the depression of the first impression element, until final at first first side of the first impression element, and second side of following depression, blocked by second side of the first impression element.Otherwise, wherein not existing in the zone of second stamping structure at those of variable visual structure, the observer only sees two sides of first stamping structure when around first inclination safety element, that is first gap tilt effect only occurs.
First and second stamping structures preferably are designed to blind blocking.Blind blocking is made by use steel engraving printed panel in printing process.Paper is pressed in the recess in blind blocking district and permanently shaping in this way in printing process.The blind blocking district of printed panel is different with the image Printing Zone not to have filling pigment, so the backing material of safe document permanently shaping only in these zones, just impression.When observing blind blocking, cause special 3D vision impression based on the effect of light and shadow.In addition, there is the blind blocking of appropriate size can also be with the easy perception of sense of touch.
If the structure that first or second stamping structure is stamped has different height, then blind blocking is also referred to as the halftoning blind blocking.
Blind blocking also can cause by the thermic method in addition.Here plastic supporting base is by the heat effect thermal deformation, and can prepare than structure meticulousr in the paper substrate this moment.This method is especially used in plastic banknote or money card, account card, credit card, SIM, subscriber card and so on.
By another kind of preferred form of implementation, first and second stamping structures are designed to color impression.Adopt color impression although replace blind blocking in this case, but still keep the effect of the variable vision of safety element.That is to say that the structure of variable vision has same at least and the data medium surface forms second coating that contrasts, the regional superimposed layout that it and stamping structure protrude in the subregion.The advantage that this second coating is brought is the printing process that the stabilisation of stamping structure need not to add.This class safety element also has an advantage in addition, and it can be combined in the printing theme of acupuncture intaglio plate, and thereby can be combined in the design of the look of theme and thing.
When making color impression, the engraved lines of printed panel is filled with pigment.Unnecessary pigment is removed from printed panel by washing barrel or scraper, makes engraved lines all be filled pigment until the edge.At last, the data medium that in printing process, will print by the pressing roller on flexible surface, normally paper is pressed on printed panel with high pressure.Data medium is pressed in the engraved lines of printed panel filling pigment and thereby contacts with printing-ink in this case.When peeling off data medium, it is taken printing-ink out of from the groove of engraved lines.The printing image of so making has track, and they change the thickness of chromatograph according to the degree of depth of engraving.Here, data medium is pressed in the groove of printed panel in this way powerfully, makes it not only to absorb pigment from groove, and meanwhile is stamped.
By a kind of particularly preferred form of implementation, stamping structure has linearity impression element, and they are preferably straight, but also can be waveform and/or crooked.Linearity impression element causes by platen or impression cylinder internal channel shape groove.Groove cross section is designed to, and makes the impression element be formed with at least two opposed sides, and each this side can be seen from different directions.For example form two sides when leg-of-mutton groove design scheme, both all can see when right-angle view.When stravismus, can only see a side, because block opposed with it that side that another side can be seen.Therefore, in vertical and inclination gap tilt effect appears when alternately observing.
Usually the linearity mesh structure of coating and linearity impression element orientation parallel to each other so arrange a kind of line of color on a side of stamping structure, is arranged the line of another kind of color on another side.Therefore if the observer looks side ways the structure of variable vision, he sees one of two kinds of colors according to line of vision, if the structure of his this variable vision of right-angle view, then he sees two kinds of colors.Therefore by the mating reaction of coating and stamping structure, produce the gap tilt effect of colour switching.
By another kind of preferred form of implementation, stamping structure has non-linear shape impression element, as especially by WO2006/018232A1 known.The side of non-linear shape impression element has flat and/or curved surface, and its shape is n incline cone, tetrahedron, the prismoid, cylindrical section, cone, truncated cone body, parabolic body, polyhedron, rectangular parallelepiped, prismatic ball section, ball section, spherical crown, ball segment, hemisphere, barrel-shaped body or annulus especially.Non-linear shape impression element also can be designed as the anchor ring that what is called is cut apart, and anchor ring was parallel to that plane earth that the anchor ring long radius is in wherein and cut apart this moment.Particularly preferably, adopt is the knot fancy impression element of spherical crown or three sides or four incline cones in form.The advantage of non-linear shape impression element is, can in the element of variable vision, hold more than two the information that can see along different viewing angles by simple mode, because non-linear shape impression element has a plurality of sides, these information or partial information can be aimed at and be configured in independently of one another on these sides.
The coating of first and/or second stamping structure and/or formation contrast has at least one information, and it constitutes by the outline line of impression or Printing Zone.Described information is designed to the form of etching and/or alphanumeric reflection, and for example shows numeral, letter, portrait, animal, plant, landscape or building.
The height of stamping structure and/or lateral dimension especially must be greater than 30 μ m owing to the roughness of seal paper money paper.
Particularly preferably, described at least a second stamping structure is divided into subregion one by one, and wherein, second stamping structure plays additional information.Second stamping structure can according to design with each subregion especially block, projection, delustring or obmub.It plays tangible information support effect when identical topology, and by reducing gradually or layout discordantly, it can promote gap tilt effect.
Coating preferably is designed to the form of the flat printed matter of monochrome or polychrome.Here the polychrome printing product particularly preferably are made up of a kind of straight-line pattern, its cathetus direct neighbor or the spacing that separates each other.Under first kind of situation, will preferably be applied on the data medium by dark blue, the pinkish red consistent straight-line pattern of forming with the alternate sequence of yellow three lines of area.The spacing if these straight lines separate each other, then preferably the color of data medium substrate constitutes the wherein straight line of straight-line pattern.Under possible situation, also can make up.If for example on the magenta substrate, print additional the alternate sequence of forming by two adjacent dark blue and yellow line, wherein each line between room of existence, then substrate constitutes this sequence and " lacks " the 3rd line.
Common versicolor line adds on the substrate that is imprinted on data medium side by side.In this case, in first printing process, at first print the line of all first kind of colors, the line of all second kind of colors of printing in second printing process, and in the 3rd printing process, print line of all the third colors or the like.Use oneself a printed panel or oneself a print roller for every kind of color, be coated with corresponding pigments above, and then add on the substrate that is imprinted on data medium.
All in principle colors also can add on the substrate that is imprinted on data medium in single printing process.Various in this case pigment successively or be coated in simultaneously on monolithic printed panel or the single print roller and then add on the substrate that is imprinted on data medium.
Print additional and adopt general printing process to realize, that is to say, especially in lithographic printing, for example use the offset printing method, in letterpress, for example in book and periodical printing or with flexography printing method, in serigraphy, in intaglio printing, for example in silk screen intaglio printing or acupuncture intaglio printing, or use the thermograph method, for example use thermal transfer method.
Preferably adopt complete opaque printed printing ink for coating.Particularly preferably also adopt the printing-ink that the good clear pigment characteristics is arranged, that is the printing-ink of forming by the colored varnish that contains certain share pigment.Equally also can adopt the colored varnish, in them, augment machine-readable feature, for example the material of luminescent substance, conducting particles or absorbing IR or X ray.Here the surface of the coating of machine-readable features and safety element forms contrast, because it does not have machine-readable feature.Certainly, machine-readable feature also can be the part of transparent or opaque printing-ink.
Preferably, the line of coating is designed to straight line, and particularly preferably is arranged in parallel with each other.These lines can be designed as concentric circles or confocal ellipse too, or ellipse, waveform or other Any shape are arranged.In addition also can make up multiple form of implementation.
Described at least a second stamping structure also can form second coating combination that contrasts with the data medium surface with one.In this case, on first stamping structure, apply first coating, and on second stamping structure, apply second coating.Therefore when observing second stamping structure, the observer finds out that is located at the inner additional information of the first stamping structure coating.
Here the coating and first and second stamping structures are tuning.Color of being aimed in the time of for example will looking side ways or pattern separate, strengthen, weaken or make it distortion, and thereby produce another additional information.In vertical view, maybe when observing opposite side, keep hidden this additional information.
Preferably, design has identical local frequency to coating with stamping structure, that is to say that the screen ruling of stamping structure and coating is identical.But also can adopt is similar local frequency, producing difference frequency or ripple effect, or abandons the described relation of local frequency fully.Can produce other visual effects thus, they only just can be seen when observing element from different angles or by different angles of light.
These two processing steps that are used to make variable visual structure, impression and printing can be by carrying out in proper order arbitrarily.For example at first stamping structure can be added in the substrate of data medium, then print additional coating, otherwise or, at first print additional coating, stamping structure is added in the substrate of data medium then.Can also in a common processing step, implement this two processing steps simultaneously equally.
By the information that impression and coating on safety element add, can for example form, but also can form by any symbol, etching element or etching, image, one dimension or 2 d code or other patterns by letter and/or numeral.
The substrate that safety element uses can be one or more layers, and in its surface or in substrate one or more layers ground coating, printing, stickup, compound, glue together or do other processing.In addition, can also be in substrate and/or on, insert or add other (also machine-readable) safe material, they can activate when causing first and/or second tilted image, block, partial destruction or elimination.Here, described other safe material preferably produce another tilted image.
Should mention that here safety element can be made up of any substrate of acupuncture woodburytype that is applicable to.Particularly preferably be paper and stationery substrate.Type to paper is not added any condition, so can use the fibrous common paper by annual plant, especially cotton fiber or paper pulp fiber.Also can use equally those to small part by plastic optical fibre, the preferred paper of forming by Fypro, that is they contain the share of polymeric material in the scope of 0 to 100 percentage by weight.Paper also can be in one or both sides and plastic sheeting combination.
It is 50g/m that ply of paper has weight usually
2To 100g/m
2, 70g/m preferably
2To 90g/m
2Certainly use any suitable weight according to applicable cases.Paper can be processed as individual layer and multilayer.To multi-ply paper, ply of paper can be made up of the paper of identical or different kind, and can make up with plastic sheeting again.
Can consider that in addition backing material is a plastic sheeting, for example polyester film.In addition, film can single shaft or biaxial stretch-formed.The stretching of film especially causes it to obtain polarization characteristic, can utilize them as another security feature.For making full use of the needed servicing unit of these characteristics is that the professional is known, as polaroid filter.
Film also can be designed as the cover plate that hides the substrate part surface, or is designed to along the band of safe document total length or overall with extension.Material as film at first can be considered plastics, especially PET (Polyethylenterephthalat PET), PBT (Polybutylenterephthalat polybutylene terephthalate (PBT)), PEN (Polyethylennaphthalat PEN), PP (Polyproyplen polypropylene), PA (Polyamid polyamide), PE (Polyethylen polyethylene).In addition, film can single shaft or biaxial stretch-formed.
Rightly, backing material also can be a kind of compound of multilayer, and it is made up of paper or paper-like materials one deck at least.This compound is characterised in that high stability, and this durability for safety element is very favorable, in addition also improves anti-counterfeit capability.
But also can consider to use the multilayer materials of no paper as backing material.These materials also can advantageously be used in some climatic province of the earth.
All raw material as backing material can have the additive as authentication feature.At first consider luminescent substance in this respect, they are preferably transparent in visible wavelength region, and can be by the servicing unit that is suitable in the nonvisible wavelength scope, the radioactive source of for example launching UV or IR ray activates, and produces luminous that a kind of visible or available at least supplementary means detects.Also can advantageously use other security features, if they do not influence or only minimal effect to the observation of printed matter.
Other layers of showing pattern or image can be in tilted image-element below/top, but they be basically the plane or adapt with the mesh of tilted image existence.For example make in this way that observer's eyes can be deflected from when straight line is overlooked original inclination information, this information just just becomes high-visible when tilting.
The gradient of the first and second impression elements and side influences the fracture characteristics of substrate.The gradient of each side is steep more, and substrate impression and elongation in this zone is strong more, thereby causes reducing the thickness and thereby the reduction fracture characteristics of substrate.
In addition, the angle between the vertical and press printing roller of first stamping structure, influence makes the danger of paper damaged during making safety element.For example angle is 0 °, that is first stamping structure be parallel to the print roller orientation, the danger of paper damaged is big especially.Yet it causes particularly advantageous slope characteristic, because safety element, for example banknote needn't rotate around axis with respect to the observer, just can directly obtain a tilted image.Therefore preferably adopt about 10 ° or about 45.If the first impression element is not a straight line, and for example be designed to corrugated, then the first impression element vertically be meant the first impression element central authorities vertically.
By the coining tool manufacturing that first indentation is arranged, in first indentation, be added to small part second indentation by stamping structure of the present invention.Here, second indentation or the geometry that changes first indentation by part add in first indentation, or always are applied on the side of first indentation with the angle of a regulation, thereby make the corresponding stamping structure of second indentation and safety element corresponding.
Preferably, this coining tool is a making ide or a bar printing plate, acupuncture gravure printing plate especially, and their indentation is designed to the die cavity in the coining tool surface.The cross section of die cavity is designed to triangle, trapezoidal, sinusoidal or semicircle here.
Particularly preferably, first and second indentations are with graver and/or with laser instrument and/or use etching method, in some process or in a process independently, are applied in the surface of coining tool.Wherein the degree of depth of indentation is about 50% of kerf width, especially equals 10 μ m to 250 μ m, is preferably 50 μ m to 120 μ m, and particularly preferably is 60 μ m to 100 μ m.
Here engraving tool is responsible for the gradient of side.By for example changing engraving tool, can process right flank with a kind of specific purpose tool, and, obtain a kind of wide, flat side with flat tool processes left surface with steep angle by the simplest design.
The advantage that the present invention gives prominence to is, provide a kind of integrated, be the additional information of second gap tilt effect in form, it causes by second stamping structure on the first impression inside, element side or side.This additional information can obtain extra support by appropriate configuration coating.Therefore realize a kind of clear and definite relation of second information by the present invention in the impression geometry inside of first stamping structure.By special arrangement coating with at second stamping structure of the first stamping structure inside, the observer can perceive the variation that with respect to the rapport of environment.
Therefore advantageously be data medium structure safety element, they are combined with each other two kinds of gap tilt effects, and can make under the condition of the machine of typical print factory and speed set-point.
Other advantages of the present invention are by the color of using or part uses finished product data medium inside to exist, to realize straight line or non-directional color gap tilt effect and the multiple color combination of conversion.In addition, people in the street or consumer need not aid and just can well discern by gap tilt effect of the present invention.
Be particularly useful for improving the false proof reliability that the valency document is arranged, for example banknote, check, stock, identity card, admission ticket, ticket, license, credit card and so on by safety element of the present invention.
By what the structure of the variable vision of the present invention especially can be combined in other any security features valency document inside arranged.As being applied on the security thread, with hologram or the combination of other diffraction structures, or it is other or overlapping with it to be arranged on the structure of other variable visions by the structure example of the variable vision of the present invention.
