Summary of the invention
Thus, technical assignment of the present invention is, provide a kind of secure file and for the manufacture of the method for this secure file be used for the device of this secure file of check, this secure file has the validity feature at the imitation improvement, this validity feature preferably can visually easily be checked.
According to the present invention, this technical assignment solves by secure file and the method with claim 14 feature with claim 1 feature and the device with claim 31 feature.
Design of the present invention is, applies at least two kinds of different fluorescent inks with different concentration curves in a zone like this, obtains perceptible change color curve (rainbow or iris).This means that the concentration ratio of described at least two kinds of different printing ink changes along label orientation on this zone.Concentration curve and selected like this by the concentration ratio change curve that these concentration curves obtain makes that the district of the marker color impression that the color stack of the fluorescence by described at least two kinds of different printing ink forms can be discovered.The color impression that serves as a mark can be selected the color impression that obtained by the stack of the color of fluorescent ink.Described at least two kinds of printing ink are selected like this, make described at least two kinds of printing ink have the different life-spans.This concept of the life-span of printing ink relates to printing ink with respect to the stability of aging, decay, transformation, decomposition etc. all the time at this.The life-span of fluorescent ink is described a time period thus, after this time period, has the dyestuff of corresponding fluorescence when being excited, the quantity of for example molecule is reduced to 1/e.At this, e is Euler's coefficient.The life-span of printing ink can be relevant with the different factors.At this, in a kind of situation, the life-span for example can be by light resistance, namely provide by the stability with respect to radiation.In another kind of situation, the life-span for example can provide by the stability with respect to surrounding environment, and for example the life-span can limit by the oxidation of carrying out by means of airborne oxygen.In another kind of situation, the life-span for example can provide by internal-response.Because the concentration ratio change curve is not constant, be that concentration ratio changes according to the position along label orientation along label orientation, so the different aging district that causes of described at least two different printing ink is along with the time is laterally mobile in this zone---described district causes the marker color impression and is also referred to as the district of marker color impression in the back.Size and concentration curve that this is regional are selected like this, make the perceptible movement in the district that perceives the marker color impression after secure file is made in predetermined valid expiration date.Thus, a kind of secure file is especially proposed, in this secure file, at least can apply at least two kinds of different printing ink (color) from the zone that a page is seen, described at least two kinds of different printing ink have the concentration curve that differs from one another along a label orientation in this zone, thus, the concentration ratio of described at least two kinds of different printing ink changes along label orientation according to the position on this zone, wherein, described two kinds of different printing ink are fluorescent inks.Select concentration curve like this, make that perceiving the limited district and the described at least two kinds of printing ink that cause the marker color impression when fluorescence excitation has the different life-spans, wherein, concentration curve and this regional size are selected like this along label orientation, make the perceptible movement that causes the district of marker color impression after making in predetermined valid expiration date.The available plain mode of movement that causes the district of marker color impression is discovered.According to the present invention, a kind of device of the validity for the test safety file is proposed, this device comprises an excitaton source, this excitaton source is used for exciting described two kinds of different printing ink to fluoresce, wherein, show that at least one information that compares the characteristic of change color curve is stored in the memory, be used for comparing with the change color curve that when the described two kinds of printing ink that excite this secure file fluoresce, perceives the ageing state of described relatively change color curve representative this secure file when described predetermined valid expiration date expires.
Comparing and be on which position and decide in the position in the district in the district of sighting target note color impression and the comparison change color curve, can judge whether the valid expiration date of secure file expires.Can compare with the position of storing thus simply in current position of trying to achieve.Memory can be such media, shows that the information of the characteristic of comparison change color curve can be stored on this media.Different with the validity date of encoding in alphanumeric symbol, the valid expiration date of encoding in the position in the district of marker color impression can obviously be difficult to imitation or copy.
In a preferred implementing form, select described at least two kinds of different printing ink like this, make and when the color stack of fluorescent ink, perceive a white color by the observer.The marker color impression thus preferably white color impression.The color impression of white is especially obviously different with other blend color that occurs in the change color curve.It is irrelevant that this and people differentially discover white color under may situation: one is perceived as white color general red, and another is perceived as blueing with this white color.
Because the life-span difference of described at least two kinds of different printing ink, the ratio of two printing ink shares is along with the time changes on the position in being applied with the zone of printing ink.This ratio advantageously changes the printing ink with longer life at this.Move along with the time thus the position that the concentration ratio of marker color impression occurs causing.Thus, the district of marker color impression is also along with the time moves.
In order for example (to realize that also the movement in the district of marker color impression can be discovered well among the 85.6mm * 54mm) at ID 1 calliper lattice under the situation of small documents, in a particularly preferred form of implementation of the present invention, propose, extend in the whole extension of this document along label orientation in described zone, especially extending abreast than longitudinal edge with respect to the file of a substantial rectangular.Thus, preferably be applied with the zone of different printing ink along the longitudinal direction extension of file substantial rectangular, card shape ground structure.If long as far as possible, then the movement that takes place in the predetermined time interval is also big especially for the length---concentration curve changes (and concentration ratio also changes thus) according to the position along label orientation on this length---of extending abreast with respect to label orientation.Make mobile discovering easily thus.At this, the displacement of time per unit is more big, and then this displacement more is easy to discover.
In that for example ((among the 125mm * 88mm) and in big label, the zone that is applied with described at least two kinds of printing ink also can selected differently aspect size and/or the orientation for 105mm * 74mm) or ID 3 specifications in ID 2 specifications under the situation of big file.Especially in the secure file made from big specification, it is favourable applying along short file limit.
In a preferred implementing form, propose, when making secure file, make a plurality of different ink compositions, these ink compositions comprise the different shares of described at least two kinds of different printing ink and are applied in adjacent area on the roller of printing machine, wherein, with these ink compositions by other roller pass to forme and from this forme pass to document body the layer.The permission that applies of carrying out strip with narrow as far as possible bar applies printing ink with the concentration curve that changes along the direction parallel with respect to the pivot center direction of roller.
Can use for the known letterpress method of professional, lithographic process, gravure process and stencil printing method and other is for the known technology that applies of professional as printing process.The printing image that produces can relate to the known arbitrary configuration for the professional, especially comprehensively, grid, half tone image or line structure.
For the printing ink transmission that realizes linking up as far as possible, namely in order to set up the continuous concentration curve of different printing ink, in a preferred implementing form, propose, described other roller is one of at least as wavers work, described wavers carries out the axial vibration campaign, in order to realize the mixing of the ink composition that is adjacent to apply by side direction string China ink.
Be proved and particularly advantageously be, carry out ink composition applying to the described zone like this, make that the concentration curve of a kind of printing ink in described at least two kinds of printing ink is that dullness reduces (increase), preferred continuous functions in described zone.This means that wherein a kind of concentration of printing ink reduces (increase) along the label orientation dullness, preferably reduce (increase) continuously.Preferred especially such form of implementation in this form of implementation, is carried out ink composition applying to the described zone like this, makes that the concentration curve of a kind of printing ink wherein is that linearity reduces the function of (increase) along label orientation on described zone.This can realize simply like this: the difference that is included in the share in the ink composition is selected constantly for the ink composition that is adjacent to be applied on the roller.Preferably apply at the edge of roller (ink foundation roller) and comprise the wherein ink composition of a kind of lion's share of printing ink (minimum share, especially wherein a kind of printing ink does not comprise fully).On opposite end, preferably apply the minimum printing ink share that comprises a kind of printing ink wherein together, do not comprise the ink composition of share (lion's share of this printing ink) especially fully.For the ink composition that is applied between it, wherein a kind of share of printing ink reduces (increase) with identical step.
Has the printing ink of ink composition as mentioned above if apply at printing process, wherein, described other roller one of at least, be that wavers carries out axially-movable and therefore causes side direction string China ink, then obtain a preferred implementing form, in this form of implementation, wherein a kind of concentration curve of printing ink reduces (increase) along the label orientation linearity on described zone.Guarantee that at this any time can see that on secure file the district of marker color and this district are along with the time moves continuously.Being proved particularly advantageous is such form of implementation, and in this form of implementation, the concentration curve of the another kind of printing ink in described at least two kinds of printing ink increases (reducing) along the label orientation linearity on described zone.This means, distinguish linearly but the concentration curve of the described two kinds of different printing ink of slope opposite in sign ground structure.
Because the district of marker color impression show as exponential relationship with movement time correlation, so one of at least life-span of described printing ink, life-span of exactly having more short-life printing ink are selected suitablely with predetermined valid expiration date.Preferred especially select so described at least two kinds of printing ink than short life, namely select to have the printing ink in corresponding life-span like this, make the described life-span be in the scope of the order of magnitude of predetermined valid expiration date.What be worth expectation is, the function of the district of descriptive markup color impression and position time correlation can by linear function approach or time range in being in the valid expiration date order of magnitude in do not have excessive deviation with linear function at least.Preferred especially such form of implementation of the present invention, in this form of implementation, being in the order of magnitude of predetermined valid expiration date or less than predetermined valid expiration date than short life of described two kinds of different printing ink, preferably than an at the most little factor 8 of predetermined valid expiration date, preferably roughly corresponding to half of valid expiration date to 1/4th.Other form of implementation proposes, and the life-span differs one more than the order of magnitude each other, and one of especially described at least two kinds of printing ink have and level off to the infinitely-great life-span.
If select concentration curve respectively like this, make that these concentration curves change linearly for the corresponding printing ink in described at least two kinds of printing ink between 100% to 0% or 0% to 100%, then save in the described zone at least one position along label orientation by described at least two kinds of printing ink absolute adjustable ratio to each other, on described position, the district of marker color impression was perceived in the moment of making secure file.The absolute ratio of preferred especially selection like this, make described zone along be distinguished into two sub regions along label orientation of label orientation by the marker color impression, the big zone in these subregions preferably along label orientation occupy this zone whole extension 66% to 90%, preferably roughly 80%.The preferred structure like this of concentration curve, make along with described at least two kinds of different printing ink produce aging, the district of marker color impression is mobile like this in this zone, makes that at first bigger subregion diminishes.
For the color impression that realizes the marker color impression improves---especially when relating to the color impression of white, in a form of implementation of the present invention, propose, apply the 3rd printing ink in described zone, the 3rd printing ink has concentration curve, have and the similar characteristic of the concentration curve of one of described two kinds of printing ink, and the 3rd printing ink has and the similar life-span of one of described two kinds of printing ink.Such form of implementation also comprises the use of mixed ink, and this mixed ink has the same life-span for two parts of mixed ink.Propose in another form of implementation, the 3rd printing ink is applied in the described zone all sidedly.Also can use other printing ink.
If can not find to have the suitable life-span and mix the speech complementation in order to cause the suitable fluorescent ink of white color impression with regard to printing ink to each other for the valid expiration date of expectation, then in another form of implementation, propose, apply the 3rd printing ink in described zone, the 3rd printing ink has the concentration curve that changes along the direction vertical with respect to label orientation.In this case, the district of marker color impression exactly be configured to point-like and along with the time not only along label orientation but also along the direction vertical with this label orientation, namely consequently move along the line of bending.
Carry out the aging check of secure file for available simple mode, preferably apply a time ruler along a curve, cause that the district of marker color impression moves along this curve, wherein, on this time ruler, preferably put on a validity limit.If the printing ink that uses two kinds of concentration curves and linearly and oppositely extend along label orientation, then described curve is straight line.Only when the 3rd printing ink that the working concentration change curve vertically extends with respect to marker color, time ruler just extends along the curve of bending.
In order under the situation of no verifying attachment, to make aging the reading simply of secure file, propose in a preferred implementing form, at least one that will obtain in the moment that valid expiration date stops relatively change color curve is printed on the described page on next door, described zone with long-life printing ink.In a further configuration, can use the long-life ink printing on next door, described zone a plurality of relatively change color curves, these long-life printing ink demonstrate the different ageing state of secure file.Thus, when fluorescence excitation, can compare with the comparison change color curve with the long-life ink printing by the change color curve that fluorescence triggers.Can realize reliable identification thus: whether the valid expiration date of file expires.
In a form of implementation, use the inspection card that is used for the comparison change color curve test safety file, that have printing like this, make inspection personnel vision ground under the situation of corresponding irradiation observe this inspection card and secure file.
Propose in a form of implementation of the present invention, the memory that is used for the device of test safety file is a face of using the long-life ink printing with described at least one comparison change color curve.
Propose at a further configuration according to the device for the test safety file of the present invention, excitaton source can be regulated aspect excitation intensity, in order to can make the intensity of fluorescence and the normal intensity that observe suitable.Because aging ink, the quantity of current printing ink pigment reduces, and thus, fluorescence intensity is also along with the time reduces.Therefore advantageously, exciting of fluorescence can be regulated, so as thus can be adaptive based on the intensity of the resulting change color curve of fluorescence.Directly after producing secure file, only need a little excitation intensity.File is more old, and excitation intensity should be selected more highly, in order to observe change color curve fluorescence, that intensity is almost identical based on two kinds of printing ink.Preferably carry out related between the position of detecting in the excitation intensity of regulating and the district of marker color impression at this, because between the two, there is fixing relation.In this way, described feature is avoided being copied more reliably.

The specific embodiment
In order to make the secure file with validity feature, two kinds of different printing ink are applied on this secure file along a label orientation with different concentration curves.Schematically correspondingly show the concentration curve 1,2 that for example is used for red and cyan ink at label orientation 3 among Fig. 1, this label orientation is drawn along the abscissa of the diagrammatic view of Fig. 1.The ordinate 4 of diagrammatic view is described the concentration of printing ink or is included in the concentration of the pigment in the printing ink.Preferred select different printing ink like this, make the color stack speech of the fluorescence that these printing ink send with regard to these printing ink under the situation of mixing suitable (concentration ratio is suitable) cause white color impression.If for example select redness and be distributed in the concentration curve that is provided with reference number 1 among Fig. 1 and represents as solid line for this first printing ink as first printing ink, select cyan and be distributed among Fig. 1 shown in the with dashed lines for this second printing ink and with the concentration curve of reference number 2 marks as second printing ink, if and also hypothesis causes white color impression when the cyan pigment of as much and red pigments produce fluorescence, then obtain the secure file 5 that illustrates extremely simplifiedly among Fig. 2, this secure file preferable configuration is orthogonal and can be by a plurality of secure files 5 that form that close layer by layer.Also can include valency printing and security printing through last gloss varnish or without secure file 5, especially paper substrate, fabric base or the plastic base of last gloss varnish, and the composite material of these materials or composite.Secure file 5 for example can preferably connect to a brochure by the page or leaf of paper structure with other in the travelling passport in other form of implementation.Shown in secure file 5 in, be applied with, especially extend at the full page of file 5 in the printing zone 7 of having gone up two kinds of different printing ink.These two kinds of different printing ink, be that cyan and red concentration curve change along label orientation 3 at this, this label orientation is orientated abreast with respect to the longitudinal edge 8 of secure file 5.
When the fluorescence of two kinds of different printing ink is excited, serve as to distinguish 9 with reference to perceiving one at the middle part of document theme with label orientation 3, this district causes white color impression, is the marker color impression.Be adjacent to be provided with district 10 and 11 with the district 9 that causes the marker color impression, these districts cause the color impression of cyan or correspondingly cause red color impression.If suppose: the printing ink pigment of cyan ink is shorter than the printing ink pigment life-span of red ink, namely has the short life-span, and then the printing ink pigment of cyan solves many than red printing ink pigment time per unit branch.Move against label orientation 3 thus the position that the quantity of cyan pigment and the quantity of red pigments equate, namely is moved to the left in the view of Fig. 2, and thus, mark zone 9 is moved to the left along with the aging increase of printing ink.This movement is the yardstick that wears out and the valid expiration date that can be used to test safety file 5 thus.If the district 9 of marker color impression is lower than a threshold value to the distance 12 of short left seamed edge 13 of secure file 5, then this can be used as for the valid expiration date of secure file 5 overdue feature use.
Schematically show a printing machine among Fig. 3, can make secure file according to Fig. 2 by means of this printing machine.In the example shown, roller (ink foundation roller) 22 that be used for to receive printing ink is also referred to as the territory 24 that ink separator 23 that branch stirs device is divided into four equal sizes in the axial direction by a plurality of.In one of any in these territories 24, carry one of four different ink compositions for roller 22.Flow to the ink composition of roller 22 by comprising inking roller 25,25 " and at least one wavers 25 ' other roller pass to forme 26 and be printed onto on the layer 27 from this forme, should layer preferred laminated or secure file of laminated one-tenth.Described at least one wavers 25 ' axis 28 carries out oscillating movement except be rotated the motion also along the longitudinal around longitudinal axis 28.The infinitely variable side direction string China ink of ink composition takes place thus, thus, forms the dullness, continuous of two kinds of different printing ink and preferred linear concentration curve---described ink composition is made of these printing ink along label orientation 3 at layer 27.
Among Fig. 4 at label orientation 3 diagrams show concentration curve 1 for red and cyan ' with 2 ', if side direction string China ink does not take place, then expect this concentration curve.Be that in this starting point described four ink compositions are by cyan, red by two parts cyan and a part, red and only be made up of redness by a part of cyan and two parts.So by the black concentration curve that obtains according to Fig. 1 of side direction string.Self-evident, for the professional, can use four above ink compositions.
In order in the district of marker color impression, to realize in some form of implementation, proposing best white impression, additionally the 3rd printing ink is applied on the described zone, the 3rd printing ink also is fluorescigenic printing ink.At this, preferably use concentration curve similar concentrations change curve with one of described two different printing ink along label orientation for the 3rd printing ink.This means that the concentration curve of the 3rd printing ink also increases (reducing) monotonously along label orientation, preferred linear increase (reducing).
