Description

TECHNICAL FIELD [0001] The present invention relates to a security document provided with a tactile mark and a region of coarse texture, and a method for manufacturing the security document.

The present invention relates to secure documents provided with tactile marks and areas of coarse texture. The invention also relates to a method for producing such a document.

In the field of fiduciary printing, the security of the printed documents has long been a problem.

To this end, the trust printer not only sees the security books, but also applies a certain number of recognizable and acceptable security books to the documents by touching them.

The latter cognitive skills are particularly relevant to those suffering from visual deficits. Thus, the above-mentioned people are not only people with visual-impairment but also people with amblyopia.

In the first phase, the person with amblyopia or time-impairment proceeds to study the form and size of the document allowing him / her to concentrate on the initial recognition of the latter. The sound generated by waving the paper of the document is also a unique sign, especially when the document is new. However, this distinct sound changes over time.

Finally, the user with ambiguous or time-impaired can not undoubtedly understand the authenticity of the document.

The recognition by the touch may be a means for identifying and authenticating the latter.

In the field of touch-based recognition, Braille languages have been developed and proved to be particularly effective. However, it is not possible for everyone with amblyopia and visually impaired to identify and read the Braille language.

On the other hand, the security printer uses a thin paper having an order thickness of 0.1 mm, which is the size of the reliefs having an order thickness of 0.8 mm to 1 mm coded by the braille language in some cases in French .

However, the so-called " intaglio " printing technique generally used by those skilled in the art for applying raised ink over secure media is limited by the height of the ink to be deposited, do.

In the field of banknotes, "Marks for the Blind" printed with relief by intaglio technology are known. Most frequently, the aforementioned marks are located on a single side of the bill, in this case located on the front side, which may be difficult to identify to a person with the amblyopic or visual impairment. As noted herein, it is interesting that there is no standard for the codification of the marks mentioned above.

Moreover, repeated use of the bill can reduce the latter's surface properties and reduce its tactile sense, making identification of the mark even more difficult.

The determination of a mark by a person with amblyopic or visual impairment generally follows the following procedure:

1. Non-professional inquiry process: This process provides overall information on characteristics such as form, size and direction;

2. SPECIFIC PROCEDURES: These processes provide information on shapes, packaging, contours, and textures.

During this specific process, a person identifies information related to the geometry of the relief elements as well as surface related information such as roughness, rigidity, resilience, and the like.

Also, when a person with amblyopia or visual impairment examines a thin object, he or she uses the index finger as well as the thumb.

In fact, he / she moves the object by touching both of the above-mentioned fingers at two opposite points. The change in distance between the thumb and forefinger informs him / her about the set or branch of the document's relief.

Beginning with this observation, it is an object of the present invention to allow identification of a specific characteristic of the document, such as a facial value in the case of banknotes, as a security document that is typically devised as a " mark for the blind & And solving the above-mentioned problems by proposing a security document for facilitating the positioning of participating protruding marks.

Thus, in accordance with a first aspect, the present invention provides a method for identifying a specific feature of a document, such as a facial value, by touching a mark for participating in an authentication decision of the document, thereby providing at least one tactile protrusion mark wherein the mark comprises at least one area of a first rough texture, that is, a touch feel, such as a tactile protruding mark or a mark for the blind, on at least one of the opposite surfaces, Is characterized by the fact that the rest of the sheet is at least partially surrounded by a different and distinct surface from the second touch's feel of the second coarse texture area.

Due to the presence of a region of coarse texture adjacent to the tactile protrusion mark, the person with amblyopia or visual impairment is more likely to have a touch feeling that is different from the touch feel of the rest of the sheet, And will more easily inform him / her of such a "unique sensory indicator element" which is located in close proximity to the mark.

Furthermore, the specificity and originality of the above-mentioned texture informs him / her about the authentication of the document that he / she is investigating.

According to advantageous and non-limiting features of this document:

The areas of the coarse texture are exactly perpendicular to one another;

The area of coarse texture comprising relief elements protruding on one of the regular planes of the sheet;

The area of the coarse texture consists of at least one pair of parts located on either side of the projecting mark;

The area of the coarse texture completely surrounding the mark;

An area of said coarse texture partially surrounding said mark;

The area of the coarse texture is adjacent to the tactile mark;

The area of the coarse texture is remote from the tactile mark;

The document comprises a tactile mark on each of the faces;

The haptic marks are not exactly perpendicular to each other, and the area of the region of the " embossed " rough texture on the front side associated with the first tactile element is " subtly " rough texture The area of the area of the " embossed " rough texture on the back surface associated with the second tactile element extends perpendicularly to the area of the " intaglio " rough texture area having a complementary shape on the front surface, Regions, wherein the portions located on the same side are complementary and the regions of the " embossed " rough texture resemble each other on the front side and the back side.

The present invention also relates to a method for producing a document that conforms to one of the above features.

According to this method, the method proceeds with simultaneous formation of the regions of coarse texture.

Moreover, according to other non-limiting features of this method:

The process proceeds with the simultaneous formation by intaglio printing;

The process proceeds with an inkless printing, so-called embossing stamp, with no ink;

The process proceeds with intaglio printing using an ink, preferably a colorless or white ink.

The method proceeds with intaglio printing using color ink.

Other features and advantages of the present invention will become apparent upon reading the detailed description of the invention in accordance with certain preferred embodiments. This description will be described with reference to the accompanying drawings, in which:

In Fig. 1, banknotes formed on a single piece of trust paper are schematically illustrated.

Also, the term " sheet " means both a monolayer and a multilayer sheet. If the sheet is a single layer, the sheet particularly comprises 100% natural cotton fibers. However, it is also possible to find, in a very small proportion, other fibers in the sheet, such as flax or manila hemp or even from synthetic fibers. The support can be entirely of petrochemical origin and can be exceptionally constructed, for example, from bi-oriented polypropylene. Finally, in the case of multilayer sheets, paper, cotton and plastic (e.g., polyester, nylon) are adjacent and laminated or molded together.

The opposite front and rear sides of the banknote are referred to as 10 and 11, respectively.

In a known manner, the front side 10 of the bill includes a tactile protruding mark 2, whereby people with amblyopia or visual impairment can identify the face value of the bill and contribute to its authentication decision Can be accepted.

Such a mark is made according to any method known to those skilled in the art, which provides the relative relative ease to the general side of the sheet to enable the person to detect perfectly and accurately by the person with amblyopia or visual impairment It would be possible to provide some of the tactile senses possible to the mark.

Preferably, in order to facilitate positioning, such tactile marks are positioned so as not to fall from the edges of the sheet. However, this is not mandatory in the above case.

According to a main feature of the present invention, said mark 2 has at least one first coarse texture area 3, i.e. a touch feeling is different from that of the rest of said sheet 1 and is quite unique in some cases, Is at least partially surrounded by a region that is at least the same but preferably larger than the extent or surface area occupied by the second face having region 4 of similarity to the second rough texture in this case.

As described above, the area of the coarse texture is defined as having a distinct or unique touch feel that distinguishes it from the rest of the touch feel of the sheet. Thus, the person who wishes to identify the document will be aware of this change in the tactile sense of the proximity to the " identifier " mark.

If the area of the coarse texture has a unique and prominent touch feel that is different from the rest of the feel of the seat, then the coarse texture area can be any feature. Thus, it can be set to provide the following feel (es) as an example, but is not limited to: specific or various geometry, that is to say with the aid elements positioned according to the optionally extended geometry, Soft, downy, felt-like, sticky, granular, hairy bristle, soft, tender, knotty, spiny, Harsh, coarse, veined, grooved, satin-like, silk-painted varnish, and so on.

Thus, when a person with amblyopia or visual impairment touches a document with two fingers and proceeds, when he / she reaches the areas 3 and 4 of the coarse texture functioning as a sensory indication element, he / she It will lead to a confirmation that the touch feeling is distinguishable from the remaining touch feeling of the seat.

To facilitate his / her investigation of such a tactile mark, this information informs him / her of the close proximity of the tactile protrusion mark.

Moreover, it is interesting to note that due to the features and other features of the rest of the document, the areas of the coarse texture described above may themselves be considered as real additional haptic marks simultaneously contributing to the authentication decision of the bill.

However, according to the present invention, it is not excluded that in other regions of the sheet the bill has at least one other rough texture area but is not associated with a haptic mark, for example if the other area is unapproved It is presented as an element that makes cloning more difficult.

Of the techniques that can be used by those skilled in the art to make the aforementioned areas of coarse textures, the most particular attention is directed to applying deformation in the overall thickness of the sheet. Intaglio printing is an example of this technique.

It is also possible to proceed with deformation by embossment, that is, deformation between a male shape and a female shape.

In other embodiments, it is possible to add an external element, such as a plastic film, or an additional ink coating, over the sheet of the document by heat or cooling movement.

Typography and stamping techniques may also be used.

Figures 2 and 3 illustrate possible implementations of areas of coarse texture in accordance with the present invention.

All of the above figures will be read in combination.

In this specific exemplary embodiment, the tactile mark 2 as well as its associated coarse texture areas 3 and 4 are produced by so-called toggle technology.

As all know, this intaglio technique consists in applying a plate onto the paper comprising a set of engravings (in this case, a series of grooves in the form of line segments) Ribs on the face facing the plate and grooves similar to the lips of the plate on the opposite side, causing the complementary deformation of the paper in the thickness of the sheet when the intaglio is applied at high pressure onto the paper.

In the embodiment described herein, the tactile projected mark 2 has a rectangular shape as viewed above, and is delimited on the front side 10 of the sheet by four lips 21 and 20 projecting over the plain side of the sheet.

Due to the intaglio technology used, the lips 21 and 20 occur on the back surface 11 grooves having a substantially complementary shape, while a recess defined by the lips 21 and 20 is formed on the rear surface Resulting in the presence of substantially complementary protruding pads.

This " practically or substantially complementary " indication is used herein spontaneously because the grooves / lips, the niche / pads do not have strictly the same dimensions. This is due to the variations of the sheet and the technique used.

Indeed, the intaglio technique is a method that does not restore the integrity of the plate. It is common to observe relief restoration rates on the paper comprised between 50% and 80% of the depth actually practiced in the plate. This level of restoration may vary depending on the equipment and paper, and may vary, in particular, depending on the pressure performed between the plate-holder cylinder and the fluting cylinder.

In the case illustrated herein, the coarse texture area 3 is composed of one pair of areas 30 and 31 located on either side of the protruding mark 2.

However, in one implementation not shown, this region of coarse texture may completely surround or partially surround the mark, such that when a person with amblyopia or visual impairment reaches the region where the tactile mark is present This is an important point for easy access to the area of the rough texture to be used.

In the case illustrated herein, all of the regions 30 and 31 of the coarse texture region 3 are slightly away from the tactile mark 2.

However, in other embodiments not shown also, the area of such a rough texture may be adjacent to the haptic mark.

According to the custom in Fig. 2, the ribs in which the front side 10 of the sheet is seen are illustrated with black lines of different thickness, while the grooves separating the two neighboring ribs are illustrated as white. The term " groove " taken into account in the front side is actually equivalent regions where the ribs are non-ribbed at the elevation 0 of the face of the sheet, in other words, It corresponds to an altitude of 0.

2, the region 30 comprises a juxtaposition of the groove 301 and the lip 300, wherein the complementary portion 30 'provided by the groove 301 and the lip 300' complementary to the lip 300 and the groove 300 ' Lt; RTI ID = 0.0 > 11 < / RTI >

In the case illustrated herein, the width 11 of the grooves is an order thickness of 200 μm whereas the width 12 of the ribs is 800 μm of order thickness.

At the same time, on the other side of the tactile mark 2, one is treated with a second coarse texture portion 31 having a lip 310 with a width 15 of 200 [mu] m and separated into a groove 311 having a width 16 of 800 [mu] m. Complementary and as already indicated in the left part of the figure, said back side comprises a complementary part 31 'consisting of a groove 310' and a lip 311 '.

The pairs of regions 30 and 31 on one side and the regions 30 'and 31' on the other side respectively form regions 3 and 4 of the first and second rough textures according to the present invention. It is important to note that the region 30 'is similar to, or even semi-identical to, the region 31 and, conversely, the region 31' is similar to the region 30.

Considering the tactile impression, the presence of the ribs will be felt if the ribs are mostly spaced apart, while the presence of the grooves will be felt if they are close to each other, and vice versa. With the Intaglio technique used, the above described elements are manufactured in a single pass in the machine.

In the embodiment illustrated in Figures 2 and 3 above, one is being treated with sets of lips and grooves. However, other types of relief patterns may be possible, which will be shown later in this description and more specifically with reference to FIGS. 7-9.

In Fig. 4, substantially the same structure as the structure of Fig. 3 is schematically illustrated, except that the intaglio plate 6 used to deform the paper sheet is also illustrated. It will be appreciated that such plates include elements 60 and 61 engraved in a complementary manner to the lips and grooves preferably obtained on the paper.

In the case illustrated with reference to the above figures, one has been treated with areas of coarse texture consisting of alternating lines that are bounded by lips and grooves. In cross-section, the latter has an angular shape similar to that of crenellations.

Applicants of the present invention have engaged in a series of measurements that allow their spacing and other categories according to the shape of the associations, the optimal detection of the fabric and the optimal form of determination that best permits sensory perception.

The data obtained are listed in the following table.

Caption:

Thickness : width of relief

Frequency (frequency) or contour (lineation): space repeatedly separated by the relief edge of the same characteristics. Accordingly, the frequency in the present invention corresponds to the thickness and the addition of the space between two lines.

The front and rear skin (tactilities): depending on the sensitivity of the touch feeling provided by the above-mentioned relief elements, the Scoring ohdeul, -, -, + and ++ is the most excellent feeling is obtained as the score ++, The worst touch was assigned to produce a hierarchy of sensitivity levels indicated as -.

Form (Shape): the latter is described in co-planar arrangement, and optionally two each in the form of the presence of a shoulder (shoulder). Accordingly, the above-mentioned form "90 ° and 45 ° shoulder 20" corresponds to a schematic example only located near the table and illustrated in FIG. Other forms shown in the table are also found in Figures 5A-5G. In all of the above tests, the intaglio plate depth of the intaglio plate was made to be 100 μm, and the use of this intaglio without any ink gave the possibility of creating a tactile effect.

However, the use of an ink-containing intaglio has the potential to create a tactile sensation on the surface accompanied by the texture imparted by the ink itself.

For example, the inks used are referred to as covering white ink SICPA 9SP0001S and transparent white ink SICPA 9SP00021. The inks may be used independently of each other or as a mixture in any ratio.

In the case of combining the functionality and security aspects of the marks for the blind and areas of the coarse texture, for the aesthetic reasons and / or technical reasons associated with the arrangement of the intaglio printing, Taglio color inks may be used.

In the case of security provided, the intaglio inks may be fluorescent, infrared irradiated or otherwise visible, provided they are provided with chemical traces and the like. It is also applied to white ink and transparent ink.

The table shows that the profile of the intaglio does not have a significant effect on the detection of the co-incident elements by touch feeling. The profile designed as "90 ° 90 °" having the form of a crenellation appears to be a retained profile. The sawtooth means changing the succession of the respective protruding elements and niches having a cross-section that can be inscribed in a square or a rectangle.

In the same way, a line, i. E., A lip having a width of 200 μm, which is spaced apart from the next by 800 μm spacing, allows optimum tactile touch on the anterior surface.

In addition, a line (lip) with a width of 800 μm, which is 200 μm apart, allows optimal tactile feedback on the back side, and smaller spacing makes it impossible to obtain superior tactile sensation.

Under the conditions described above, the regions 30 'and 31 are sites that provide better " tactile ", i.e., the best sensitivity to the fingers of the " tester ".

The application of the teachings described above is also illustrated in Fig. 6, where two tactile marks 2 located on one of faces 10 and 11, respectively, were illustrated on the same sheet 1. The haptic marks described above are not located exactly perpendicular to each other.

The region 30 of the region 3 of the " embossed " coarse texture on the front side associated with the first tactile element 2 is the region of the " intrinsic " rough texture region 4 having a complementary shape on the rear side 1 While the region 31 'of the region 4 of the «embossed» rough texture on the rear face 11, which is associated with the second tactile element, extends perpendicular to the front surface 10, The regions 30, 31 and 30, 31 'located on the same plane 10, 11 are complementary to each other.

Thus, it is possible to apply by applying the rough texture areas on both sides of the bill in a single technically advantageous step, by means of the intaglio printing technique.

The table below provides the depth of the reliefs obtained according to the technique used, recognizing that the intaglio plate has an intrinsic depth of 100 μm. The prints are produced on a Taglio machine, which is " testing ".

Measurements performed on the Altisurf 500 (registered trade name). Example Line (90 ° 90 ° profile)
Thickness / Spacing (μm) Front side relief
(μm) Back side relief
(μm) Embossing
stamp 200/800 49.3 800/200 43.9 transparent
White 200/800 38.9 800/200 51.1 Covering
White 200/800 58.2 800/200 57.7

The depth of the intaglio plates on the plate would be at least 50 μm, ideally 100 μm.

The thickness of the intaglio line is e and E is the space or gap between the two lines. F is the frequency of the contour, i.e., the distance between two lines in the present invention.

According to definition: e + E = F

The present invention for giving tactile cognitive commands tested by people with amblyopia / visual impairment in one panel would ideally be suitable for the following formulas:

e > 100 [mu] m, and preferably 200 [mu] m

F ≥ 500 μm, and preferably 1,000 μm

The formulas are E = F - e > 400 [mu] m, and preferably 800 [mu] m.

Figs. 7-9 illustrate tactile marks 2 close to the front side of the document as top views and areas of coarse texture adjacent to them. Fig.

Traditionally, the regions are illustrated in a black overhang for the plain plane of the sheet, while the regions illustrated as white are recessed.

The above figures show that, in addition to alternating lines that limit the grooves and ribs, other relief shapes can be used.

Thus, in FIG. 7, one is treated with square-shaped portions illustrated in black and other sizes.

In Figures 8 and 9, four-sided star shapes are used.

Finally, in FIG. 10, this is a tactile mark 2 surrounded by a coarse texture area 3, where the part 31 of the area 3 consists of small protruding squares that are arbitrarily extended, whereas the part 30 is arbitrarily unfolded It has small square voids. The squares are equal in size and do not have any angular rotation relative to each other (i.e., the squares are oriented in the same direction).

Figure 11 is similar to Figure 10, except that it is a form of the protruding or niche elements that may have any form. Moreover, the aforementioned elements are positioned relative to each other in an arbitrary manner.

Of course, the above examples are non-limiting.
