Description

Being provided with can stereognosis mark and the security document having texture region and preparation method thereof

Technical field

The present invention relates to a kind of being provided with stereognosis to mark and have the security document of texture region.The invention still further relates to a kind of method for making this document.

Background technology

In security printing field, the security of printed document is important.

For this reason, the safety measure of some is applied on document by security printer, and described safety measure is by observing it and being discernible and appraisable by carrying out touch to it.

Rear a kind of recognition technology is correlated with especially, especially for the personnel affected by visual impairment.Therefore these personnel are personnel visually impaired, and also have the incomplete personnel of eyesight.

In the first phase, the incomplete or personnel visually impaired of eyesight carry out the study of the shape and size of document, and this allows him/her to complete to identify first of document.The sound that the paper rubbing document by folding sends also is distinctive signal, particularly when document is newer.But As time goes on this special sound can change because of aging.

Finally, the incomplete or user visually impaired of eyesight can not assess the authenticity of document thus far and away.

Undertaken identifying should be can as identification and the means identifying document by touching.

Undertaken in the field identified by touching, braille code is developed and is proved to be effective especially.But all eyesight incomplete sum personnel visually impaired oneself can both discover and read braille code.

On the other hand, security printer uses the thin paper with the thickness of about 0.1mm to open, this not with the size fit of the relief by braille code coding, braille code has the thickness of about 0.8mm to 1mm, is under any circumstance not always the case within the border in France.

But, the restriction of the level of ink (that is, being approximately 100 μm at the most) that can be subject to depositing for so-called " intaglio plate " printing technology ink exceeded is applied on mounting medium usually used by those skilled in the art.

In field of banknotes, by gravure application, " mark for blind person " that be printed as relief is known.The most normally, these marks are positioned on the one side of bill (being front in this case), can be isolated thus and incomplete or personnel visually impaired can be difficult to perceive for eyesight.Here emphatically point out, there is no standard to manage compiling of these marks.

In addition, reuse bill and can reduce the surface characteristic of bill and reduce its sense of touch, this can make the qualification of mark more difficult.

By eyesight, incomplete or personnel visually impaired determine that mark follows following program usually:

1, non-specifically detect program: this program provides the overall information of the characteristic in such as shape, size and orientation;

2, specific program: this program provides shape, packaging, profile, quality information etc.

During this specific program, personnel recognize the information relevant with surface such as such as roughness, hardness, elasticity and also have the information relevant with the geometry of relief element.

It is further observed that during or article that visually impaired personnel inspection thin incomplete when eyesight, he/her not only uses his/her forefinger but also uses his/her thumb.

In fact, his/her point contrary on two to be taken article then make two to point mobile with these two fingers.Distance change between thumb and forefinger is informed the convergence of the relief of his/her document or disperses.

Summary of the invention

Based on such observation, the object of the invention is to solve the problem by proposing a kind of security document, for this document, facilitate the location of the energy stereognosis mark of the projection being usually designated as " mark for blind person ", the mark of this projection allows the specific features of this document of identification, such as its denomination (when this document is banknote), and participate in the qualification of document.

Thus, according to first aspect, the present invention relates to a kind of security document of the such as banknote formed by a sheet, a surface at least in its opposed surface comprises at least one tactile raised indicia or " mark for blind person " for described sheet, at least one tactile raised indicia described or " mark for blind person " can allow visually impaired or incomplete personnel of eyesight to recognize the specific features of described document by touching described mark, such as its denomination, and the determination of the authenticity of described document can be participated in, described mark first has texture region (textured area) to surround by least one at least in part, described first has texture region i.e. its sense of touch to be different from and can distinguish over the surface of the sense of touch of the remainder of a described sheet, described second surface also has second and has texture region.

Be to be understood that, be close to tactile raised indicia owing to there being texture region to occur, incomplete or the personnel visually impaired of eyesight will more easily distinguish can the position that exists of stereognosis mark, because there is texture region (be different from its sense of touch and can distinguish over the sense of touch of the remainder of a sheet) to inform (by such as " distinguishing sensation indicator element "), he/her is in close proximity to described mark.

In addition, the specificity of these textures and originality inform the authenticity of his/her document (he/her checks).

Detailed description of the invention

In FIG, the banknote formed by the antifalsification paper of one sheet is very schematically illustrated.

Term " sheet " also means that individual layer opens sheet and multilayer opens sheet.When for individual layer, a sheet particularly comprises the natural cotton fiber of 100%.But may open in sheet at individual layer other fiber being derived from flax or abaca or even synthetic fibers found compared with small scale.Carrier can be derived from petrochemical completely and exclusively such as be made up of two-way polypropylene.Finally, when multilayer opens sheet, paper, cotton and plastics (such as: polyester, nylon) are adjacent, and are laminated or pinched together.

The contrary front and back of this bill is denoted as 10 and 11 respectively.

In a known manner, the front 10 of bill comprises tactile raised indicia 2, and this raised indicia 2 can allow the incomplete or personnel visually impaired of eyesight recognize the denomination of described bill by touching this mark 2 and can contribute to determining its authenticity.

This mark is made according to the method that any art technology person people is known, thus make him/her can provide some reliefs relative to the general plane of sheet, and for a sheet provides, some can incomplete or personnel visually impaired be capitally and the sense of touch clearly perceived by eyesight thus.

Preferably, and for the ease of location, the edge that this tactile mark is oriented to apart from a sheet is not very far away.But this is not enforceable situation.

According to principal character of the present invention, mark 2 first is had texture region 3 (be namely different from the sense of touch of the remainder of a sheet 1 to its sense of touch of this region and be all under any circumstance distinguishing especially, and the scope in this region or surface area at least equal but the scope be preferably more than occupied by described mark or surface area) to surround by least one at least in part.Open the second surface of sheet, have texture region 4 for back surface 11 also has second of similar range in this case.

As mentioned above, texture region is had to be defined by having different, distinguishing sense of touch (its sense of touch with the remainder of a sheet differentiates by this sense of touch).Attempt to recognize that therefore the change by sense of touch order is learnt " identification " mark just nearby by the personnel of document.

Described have texture region can have any characteristic, as long as this has texture region to have distinguishing, the significant sense of touch different from the sense of touch of the remainder of a sheet.Thus, this has texture region can be configured to provide following sensation (exemplarily and be not limited thereto): concavo-convex, soft, fine hair, felted, adhesion, granular, bristle, smooth, fragile, dross, thorniness, uneven, coarse, thick and stiff, coarse grain, train of thought, groove, satin shape, silk sliding, dipping, the relief element etc. of locating according to specific or variable geometry (namely optionally extending).

Thus, in eyesight, incomplete or personnel visually impaired continue to touch document with two fingers, when he/her arrive be used as sensation indicating member have texture region 3 and 4 time, he/her can discover the sense of touch to have the sense of touch of texture region 3 and 4 to be different from the remainder of a sheet.

This information notification he/her just very close to tactile raised indicia, find this tactile mark to facilitate him/her.

In addition, meaningfully it is to be noted, can consider these had texture region (due to characteristic distinguishing with the remainder of document) self stereognosis to mark as the additional of practicality of the authenticity contributing to determining bill simultaneously.

But, according to the present invention, do not get rid of the following fact: in another region of sheet, bill also have at least one other but with can stereognosis do not mark be associated have texture region, this other region is such as rendered as and makes the unauthorized of document copy more difficult unit.

In the operable making of those skilled in the art, these have in the technology of texture region, the most it is envisioned that a sheet are applied to those technology of distortion in the whole thickness of a sheet.Intaglio printing is an example of this technology.

Distortion can also be proceeded by concavo-convex, namely be out of shape between convex and spill.

In other embodiments, by hot transfer printing or cold transfer printing, external unit (such as having the plastic sheeting of particular texture) or other ink coating can be added on a sheet of document.

Also typography and stamping technique can be used.

Fig. 2 and Fig. 3 shows according to the possible embodiment having texture region of the present invention.

Fig. 2 and Fig. 3 should combine and carry out reference.

In this certain exemplary embodiments, energy stereognosis mark 2 and the texture region 3 and 4 that has be associated are made by so-called gravure application.

As everyone knows, this gravure application comprises and will comprise one group of rag (in this case, here be the groove of a succession of line segment form) forme be applied on paper, when forme applies high pressure on paper, the thickness of a sheet produces the complementarity distortion of paper, on the surface in the face of forme, present burr thus, and present the groove similar with the groove of forme on opposing surfaces.

In embodiment described here, can stereognosis raised indicia 2 rectangular shaped and burr 21 and 20 above the general plane projecting into a sheet on the front 10 of a sheet by four when observing from top define.

Due to used gravure application, burr 21 and 20 produces the groove with almost complementary shape overleaf on 11, and the recess defined by burr 20 and 21 causes occurring substantially complementary raised pads on the back side.

Here the appointment of " almost or substantially complementary " is used of one's own accord, because groove/burr, recess/raised pads non-critical has same size.This is distortion due to sheet and due to used technology.

In fact, gravure application is the method for whole rag of forme of not reducing.Generally observe on paper be included in the actual rag degree of depth in cutting blocks for printing 50% and 80% between relief percent reduction.This reduced level is according to equipment and paper and particularly variable according to applied pressure between forme holding cylinder and printing cylinder.

In situation shown here, a pair position 30 and 31 on the both sides having texture region 3 to comprise to be positioned in raised indicia 2.

But, in a unshowned embodiment, this has texture region can surround completely or surrounded by mark part by mark, main points be the incomplete or personnel visually impaired of eyesight can easily close to described in have texture region so that the position occurred to Danone stereognosis mark.

When shown here, there are two positions 30 and 31 of texture region 3 slightly apart from stereognosis marking 2 some distances.

But in other embodiment unshowned equally, this has texture region immediately can stereognosis mark.

By convention in fig. 2, the burr that the front 10 of opening sheet presents is shown as the black line of different in width, and is illustrated with white by the groove that two adjacent burrs are separated.Equivalent corresponding without relief areas (contrary without fringe area with intaglio plate) in fact with 0 At The Height of plate plane of the term " groove " that front is considered.

When considering the left part of Fig. 2, position 30 is made up of groove 301 arranged side by side and burr 300 arranged side by side, gravure application for generation of these reliefs presents complementary position 30 ' on 11 overleaf, and complementary position 30 ' is provided with and the burr 301 ' of groove 301 and burr 300 complementation and groove 300 '.

In situation shown here, the width 11 of groove is about 200 μm, and the width 12 of rib is about 800 μm.

Concurrently, the opposite side of stereognosis mark 2 can be furnished with the second have texture position 31, the second to have texture region 31 to have burr 310 that width 15 is 200 μm, burr 310 is that 800 μm of grooves 311 are separated by having width 16.Complementary ground, and as accompanying drawing left part as indicated in, the back side comprises the complementary position 31 ' be made up of groove 301 ' and burr 311 '.

The position 30 and 31 of described one side in pairs and position on the other hand 30 ' and 31 ' form respectively has texture region 3 and 4 according to of the present invention first and second.Be important to note that, position 30 ' is similar to, or is even approximately equal to position 30, and position 31 ' is similar to position 30 on the contrary.

About sense of touch, burr is by farthest isolated position, and the existence of burr will be felt, and the position that burr is close to each other, and the existence of groove will be felt, and the situation of burr is on opposing surfaces like this equally on the contrary.Pass through used gravure application, these elements are made by one way in the machine.

In the embodiment shown in described Fig. 2 and Fig. 3, be furnished with burr in groups and groove.But the embossed pattern of other shape is also feasible, as by subsequently in the description and more particularly with reference to Fig. 7 to Fig. 9 see.

In the diagram, schematically show the structure substantially the same with the structure of Fig. 3, except intaglio plate 6 is used to make paper to open except sheet distortion is also illustrated.It should be noted that this forme comprise in the rag element 60 and 61 of shape being desirably in burr and the groove complementation that paper obtains.

When shown by these accompanying drawings, be furnished be made up of the lines defining burr alternately and groove have texture region.Burr and groove are in cross-section in the angular shape being similar to crenellation.

The applicant completes a series of measurement, thus make it possible to the shape according to relief, the spacing according to relief and other standard determine to make it possible to discover as well as possible with sensibility assess the optimum shape of texture.

The data obtained are listed in the following table.

Table

Illustrate:

Thickness: the width of relief

Frequency or linear structure: the spacing that the relief edge with identical characteristics separates by repeatability ground.The increase of the spacing thus between the increase of frequency and thickness here and two lines is corresponding.

Front sense of touch and back side sense of touch: according to the sensitiveness of the sense of touch provided by these relief elements, score--,-,+and ++ be specified to the classification producing sensitiveness grade, best sense of touch benefits from score ++, and the poorest sense of touch is labeled as--.

Shape: shape is described as two angles arranged side by side and has the form of shoulder alternatively.Thus, shape " 90 ° with 45 ° of shoulders 20 " is corresponding with the sketch being arranged in table immediate vicinity, and this shape is also illustrated in figure 5b.Other shape shown in table can also find in Fig. 5 A to Fig. 5 G.In these tests whole, the rag degree of depth of intaglio plate is formed into 100 μm and when without any using this intaglio plate to provide the possibility producing sense of touch effect when ink.

But, use the intaglio plate with ink to provide the possibility of the sense of touch---it is attended by the texture sensation provided by ink self---on generation surface.

The ink used is for being such as called as those of SICPA9SP0001S (it is for covering white ink) and SICPA9SP00021 (it is transparent white ink).They can use independently of one another or use as the mixture mixed with any ratio.

When for aesthetic reasons and/or the technical reason relevant with the configuration of intaglio printing, or in order to the functional of the mark by being used for blind person and have the functional of texture region combined with security aspect, intaglio plate colored ink can be used.When specify security, base gravure ink can be fluorescigenic, visible or sightless under infra-red radiation, be provided with chemical impression etc.This is also applicable to white ink and transparent ink.

Upper table demonstrates, and the profile of rag does not have large impact to being discovered relief element by sense of touch.Seem, the profile being appointed as the shape of the indentation thing of " 90 ° 90 ° " can be the profile retained.Crenellation means a succession of projection element alternately and has recess, and recess has separately and is carved into cross section with square or rectangle.

In the same way, have the lines of the width of 200 μm, namely burr (it is opened by the spacing of 800 μm and next bar interval) can produce the optimal feel on front.

And, the optimal feel on the back side can be produced by 200 μm of isolated lines (burr) with the width of 800 μm, and less spacing can not make good sense of touch obtained.

Under these conditions, position 30 ' and 31 is to provide the region of " sense of touch " preferably, that is, for the finger of " tester " provides best sensitiveness.

Also show the application of these instructions in figure 6, on same sheet 1, wherein show two energy stereognosis marks 2 on that is positioned at separately in surface 10 and 11.These can not be positioned to coincide with one another by stereognosis mark.

" positive " on the front 10 be associated with the first energy stereognosis element 2 has the position 30 of texture region 3 to have the position 30 ' of texture region 4 to extend with coinciding with " feminine gender " with complementary shape on the back side 1, and can " positive " on the back side 11 that is associated of stereognosis element have " feminine gender " with complementary shape on the position 31 ' of texture region 4 and front 10 to have the position 31 of texture region 3 to extend with coinciding with second, thus be positioned at described position on same surperficial 10,11 30,31 and 30,31 ' complimentary to one another.

By gravure application, therefore can be applied with texture region by single step on two surfaces of bill in order to try, this is particularly advantageous technically.

Following table gives the degree of depth of obtained relief according to used technology, and wherein known intaglio plate has the rag degree of depth of 100 μm.Be printed on " testability " intaglio press and carry out.

Test in the upper execution of Altisurf500 (registration mark).

The degree of depth of the rag on forme should be at least 50 μm, and is desirably about 100 μm.

The width of rag lines is represented and E represents spacing between two lines or gap with e.F, as the frequency of linear structure, is namely the distance between two lines here.

Have according to definition: e+E=F

The present invention in order to meet the directionality of tactile recognition, by one group of eyesight not exclusively/personnel visually impaired test, and should meet following formula in theory:

E >=100 μm, and preferably e >=200 μm

F >=500 μm, and preferably F >=1,000 μm

They ensure that E=F – e >=400 μm, and preferably E=F – e >=800 μm.

Fig. 7 to Fig. 9 shows close energy stereognosis mark 2 on the front of document by top view and it adjacent has texture region.

Traditionally, be projected on the general plane of a sheet with the position shown in black, and be recessed with the position shown in white.

Shown in these accompanying drawings, except the lines of the restriction groove that replaces and burr, also can use other relief form.

Thus, in the figure 7, be furnished with and illustrate with black and there is the square position of different size.

For Fig. 8 and Fig. 9, employ circular and four limit stars.
