Description

ID, VALUE OR SECURITY DOCUMENT AND THE PROCESS AND DEVICE FOR PRODUCING SUCH

The present invention relates to an identity document, document of value or security document with a base body which comprises a surface on which or in which a labeling field is applied which is designed, a document-proof one

Colorant when it is applied, especially when writing on it

Add and / or add labeling field. The invention also relates to a method and a device for producing an identity card, valuable or

Security document.

In business dealings, it is still common practice to conduct a large number of legal transactions by handwritten declarations of intent

to be legally binding. Examples include signing sales contracts, signing checks or bank instructions, etc.

mentioned. In order to authenticate and assign a signature to a person, it is common for identification, value or security documents that are assigned to a person to be provided with a signature of this person.

In some embodiments, it is common for the person to sign, for example, on a paper form which is an inlay, i. H. as an inner layer, is inserted into the polymer layer composite. Other

Embodiments provide that based on the signature template a

Laser engraving is carried out in a preferably inner polymer layer.

The disadvantage of this method is that it is marked with the signature is only possible with a high outlay on equipment or the signature must be provided before the security document is created.

In order to be able to apply the signature to an identification document, value document or security document at a later date, as is common with credit and bank cards, for example, these are provided with a labeling field that can be placed on or in a

Surface, which consists of a plastic material, is applied. Such a labeling field, which is also referred to as a signature field, consists of a material which accepts and accepts a colorant that is indelible to documents, for example in the form of a pen color, in particular in the form of the ink of a ballpoint pen.

Taking on and taking on document-proof color is a

Labeling field understood that the color applied during labeling leads to permanent and visible identification of the labeling field. A colorant that is indelible to documents is to be understood as one that is used in his

Applying or labeling on and into the material of the labeling field is introduced in such a way that this colorant cannot be removed again from the labeling field without damaging the latter. In particular, labeling fields that are made from a paper material or based on a paper material are suitable here. As a rule, these have an irregular and slightly roughened microstructure and therefore do not only accept ink on an external surface. Rather, part of the ink penetrates the microstructured surface, so that the paint or ink cannot be removed without leaving any residue, even with the use of solvents, or without changing the labeling field.

To ID, value or security documents that contain a variety of

Include security features to provide such a labeling field, it is common in the prior art to provide a labeling field, i. H. for example a strip of security paper on the outside of a stack of substrate layers

to be laminated to the security document body.

Here, the substrate layer stack is arranged together with the Labeling field arranged between so-called laminating sheets, through which the heat and pressure are applied to the substrate layers.

In DE 10 2008 032 563 A1 by the applicant, a writing field based on paper is heated under the action of ultrasonic waves on its contact surface with an underlying polymer layer. The cooling takes place under the action of pressure, so that the paper-based labeling field forms a non-destructive detachable connection with the underlying polymer layer. The identification, value or

Security document, the manufacturing process described therein and the device described therein for manufacturing the ID, value or

Security document have proven themselves well in practice.

It is therefore the object of the present invention to specify an alternative identity document, value document or security document, an alternative method and an alternative device for producing an identity document, value document or security document.

The above tasks are carried out with an ID, value or

Security document with the set of features of claim 1, solved with a method with the set of features of claim 7 and with a device with the set of features of claim 11. Advantageous configurations with expedient developments of the invention are given in the dependent

Claims stated.

The identification, value or security document according to the invention is characterized in particular by the fact that the inscription field comprises or consists of a layer of a lacquer that can be written on or written on by means of the colorant.

A lacquer is a liquid or powdery coating material that is applied thinly to objects and is built up into a continuous, solid film through chemical or physical processes (e.g. evaporation of the solvent). In the present case a so-called functional lacquer is used, is provided with special properties. It fulfills the function of accepting and / or taking up a document-proof colorant. The lacquer can be formed as a pigment-free, colorless clear lacquer. Alternatively, the lacquer can also be colored and thus provided with pigments.

The colorant is a coloring substance that can be applied to or incorporated into the paint. The colorant can be an indelible dye that is dissolved in a solvent and / or a binder.

The dye is typically formed as a writing instrument and / or inkjet ink. In the case of a colorant in the form of a writing instrument ink, one speaks of a “pen color”. It should be noted that the colorant can alternatively also be a document-proof pigment or pigment dispersion which is applied to or incorporated into the paint.

The use of the writable varnish or the writable ink has the advantage that the inscription field can be applied to the base body in a simple manner using printing technology, which at the same time saves time in the production of the identity document, security document or security document.

The identification, value or security document is preferably in ID 1, ID 2, ID 3 or any other format, for example in booklet form, as in the case of a passport-like object. The identity document, value document or security document is generally a laminate made up of several document layers that are precisely connected to one another under the action of heat and under increased pressure. These products should meet the standardized requirements, for example ISO 10373, ISO / IEC 7810, ISO 14443.

As an ID, value or security document, for example

Passport, an identity card, a driver's license or another ID card or an access control card, a driver's license (e.g. FSD, "Driver's license

Germany "), a driver qualification certificate (" FQN "), a vehicle registration document, a vehicle registration document, a visa, a check, other means of payment, in particular a bank note, a check, a bank card, a credit or cash card, a customer card, a Health card, chip card, company ID, proof of eligibility, membership card or other ID document question, whereby it should be ensured that this has a labeling field or is attached to it.

The lacquer preferably comprises a matting powder. This promotes the sticking of the pen color. The lacquer preferably comprises 40-95% (preferably 50-80%) polyethylene glycol di (meth) acrylates with a relative molecular weight of about 400 to about 1000, which favors film formation. In addition, the lacquer preferably comprises 5-50% (preferably 10-30%) mono (meth) acrylates such as ethylene glycol mono (meth) acrylate or polyethylene glycol mono (meth) acrylate with a relative molecular weight of 120 to approx. 1000, which makes the Label field improved. In addition, the lacquer preferably comprises 0-30% (preferably 2-15%) of crosslinkers, for example polyfunctional esters with at least 3 (meth) acrylic acid groups, which corresponds to the reaction rate and

Film hardness improved. In addition, the paint preferably comprises 0.5-5%

(preferably 1 -3%) photoinitiators such as benzil dimethyl ketal, α-hydroxyketone, phosphine oxide and the like. a., which contributes to the hardening of the paint. To a

To enable the inscription field to be written on with a graphite pen (pencil), the lacquer can also contain 0-6% (preferably 0-3%) microfine fillers such as polyamide powder, polymethyl methacrylate spheres or silica gel. Solvent can preferably be added to the paint, preferably in a ratio of up to 5 parts of solvent to 1 part of paint, which leads to a reduction in viscosity and an improvement in the

Surface structure can contribute.

The layers of the base body preferably consist of a material that is suitable for lamination. For this purpose, in particular at least one layer of the base body is formed from a thermoplastic. The identity document, valuable or security document, however, preferably comprises several polymer layers connected to form a monolithic polymer layer composite, which are formed from a polymer selected from a group comprising polycarbonate (PC), in particular bisphenol A polycarbonate or a polycarbonate, formed with a geminally disubstituted bis (hydroxyphenyl) cycloalkane, polyethylene terephthalate (PET), their derivatives such as glycol-modified PET (PETG), polyethylene naphthalate (PEN), polyvinyl chloride (PVC), polyvinyl butyral (PVB), polymethyl methacrylate (PMMA), polyimide (PI), polyvinyl alcohol (PVA), polystyrene (PS), polyvinylphenol (PVP), polypropylene (PP), polyethylene (PE), thermoplastic elastomers (TPE), especially thermoplastic polyurethane (TPU), acrylonitrile butadiene Styrene copolymer (ABS) and their derivatives. In addition, the document can also be made from several of these materials. It preferably consists of PC or PC / TPU / PC. The polymers can be either filled or unfilled. In the latter case, they are preferably transparent or translucent. if the

Polymers are filled, they are opaque. The above information relates both to films to be joined together and to liquid formulations that are applied to a preliminary product, such as a protective or topcoat.

The document is preferably produced from three to twelve, preferably four to ten, films. The foils can also have printed layers. A laminate formed in this way can then be coated on one or both sides with the protective or topcoat or with a film. The film can in particular be a volume hologram, a film with a surface hologram (for example a kinegraphic element) or a scratch protection film. Overlay layers formed in this way protect a security feature arranged underneath and / or give the document the required abrasion resistance.

In this context, the possibility is also opened up that at least one area of a polymer layer of the base body covered by the inscription field has an imprint with one or more security features, the inscription field being designed in such a way, at least partially electromagnetic radiation

to let through. In this way, it is possible that there is an imprint with a security feature on the base body, which can be detected due to the translucent or transparent inscription field. In order to detect a level 1 security feature, it has also proven to be useful if the electromagnetic radiation that is transmitted is selected from one

Spectral range of the light visible to a person. The security feature can be a special pattern, an ornament or the like, which is preferably a guilloche print. The commitment of others

Security features is also possible. The method according to the invention for producing an ID, value or security document discussed above is characterized in particular by the following steps:

A) providing a base body comprising a surface,

B) printing on at least one layer or the surface of the

Base body with a layer of a writable lacquer, and

C) drying the printed layer of the writable lacquer and

thereby forming an inscription field that is formed

document-proof colorant when it is applied, in particular when writing on the labeling field.

This indicates an alternative production to a paper-based labeling field in which the labeling field

is applied by printing on the base body. The advantages and various embodiments described in connection with the identification, value and security feature apply equally to the method according to the invention.

In order to provide a drip-free application of the labeling field, in particular with a labeling field of predetermined dimensions, it has been found to be advantageous if the layer or the surface is printed by means of a pad printing device which has a cliché comprising an engraving, the lacquer being incorporated into the engraving of the cliché by means of a

Ink application unit is introduced, with excess varnish being removed from the cliché by means of a doctor blade, and with the varnish in the engraving being transferred to the layer or the surface of the base body by means of a pressure pad.

Reliable curing and permanent adhesion of the paint to the

The base body can be achieved in that the layer from the

writable lacquer is dried by irradiation with electromagnetic waves from the ultraviolet spectral range. In order to be able to provide a plurality of security features in a composite, thus in a laminate of a base body, it has proven to be advantageous if the base body is formed from a plurality of polymer layers which, before it is made available, form a stack of polymer layers

collected and laminated to a monolithic polymer composite.

The device according to the invention for producing an identity document, document of value or security document discussed above comprises a pad printing device, which uses a cliché comprising an engraving, an ink application unit

Incorporating the lacquer into the engraving of the cliché, a squeegee for removing excess lacquer from the cliché, and a pressure pad for transferring the lacquer in the engraving to a layer or a surface of a base body provided. The lacquer is also designed in such a way that a colorant that is indelible to documents, in particular a

indelible pen color is applied to and / or recorded in his orders, in particular his writing on a labeling field formed from the lacquer.

Such a device enables the printing technology to apply a

Labeling field on a base body. Those in connection with the ID, value or security document as well as in connection with the

inventive method mentioned advantages and advantageous

Refinements also apply accordingly to the device according to the invention.

In order to be able to provide the base body in a multilayer composite, it has been found to be advantageous if a lamination device is present for laminating a stack of assembled polymer layers to form a monolithic composite which forms the base body provided.

For permanent attachment of the inscription field and for hardening of the inscribable lacquer, it is advantageous if a drying device is present for drying the lacquer or the paint which has been applied to the layer or the surface of the base body. In this context it has proven to be useful if the

Drying device comprises a light source which is formed

emit electromagnetic radiation from the ultraviolet spectral range. This brings about a particularly fast and efficient curing of the paint.

To reduce cycle times in the production of a plurality of identity, value or security documents, it has proven to be advantageous if the devices of the device are arranged in a line, thus inline, along which a transport device is guided at the same time. The

The transport device can for example be a conveyor belt. However, it can also comprise a gripper or transfer gripper. At the same time, a movable robot gripper can be used to approach the individual devices of the device.

The present invention is explained in more detail below with reference to figures, the examples shown being merely exemplary and not representing any restriction with regard to the scope of the invention described. They show in detail:

1 shows a schematic perspective illustration of an identity document, value or security document in the form of a card with a

Labeling field;

Fig. 2 is a schematic plan view of an inscription field provided

ID, value or security document;

Fig. 3 shows a device for producing an identity card, value or

Security document; and FIG. 4 shows a schematic detailed view of the application process of the

Labeling field on a base body by means of a

Pad printing device. FIG. 1 shows an identification, value or security document 100 provided with a labeling field 108, which can be used as a personal document such as a passport, an identity card, an access badge or the like, a check card or a driver's license or a driver qualification certificate or another document can be formed. The ID, value or

In the present case, security document 100 comprises a base body 102 which comprises an upper surface 104 to which or in which the inscription field 108 is applied. Of course, there is also the possibility that the lower surface 106, shown covered in FIG. 1 and therefore not visible, has been provided with such an inscription field 108. The labeling field 108 is designed to accept and / or receive a colorant that is indelible to documents, in particular the ink of a pen, when writing on the labeling field 108. In the present case, the inscription field 108 is formed from a layer 112 of a lacquer that can be written on using the indelible colorant. Of course, the inscription field 108 can also comprise several such layers 112. The writable lacquer preferably comprises matting powder, as a result of which the colorant which is indelible to documents can adhere even more reliably. As can also be seen from FIG. 1, the base body 102 is formed in the present case from a plurality of polymer layers 110, which preferably consist of polycarbonate. The individual layers can be unfilled or provided with fillers. In the latter case they are opaque, otherwise transparent. Because the individual

Polymer layers 110 can form a monolithic block which practically cannot be split, in the present case the polymer layers 110 that were still isolated prior to lamination are only shown visibly for illustration purposes, the interfaces no longer being visible in the finished laminate. Individual polymer layers 110 can additionally be provided with a printing layer in order to embed security features in the polymer layer composite 114, for example.

In the alternative embodiment of an identity document, value document or security document 100 according to FIG. 2, a security feature 500, for example in the form of a

Guilloche is printed under the polymer layer 110 forming the upper side 104. The top 104, and therefore its polymer layer 110, is preferably formed as a plastic protective film or as a protective lacquer, this being transparent, so that underlying information remains visible from the outside. In this refinement, the inscription field 108 is designed to allow electromagnetic radiation to pass through. In the present case, this electromagnetic radiation is one from the spectral range of light that is visible to a person. Thus, the inscription field 108 is also transparent or at least translucent, so that the area of the base body 102 lying below the inscription field 108, in particular the security feature 500, remains visible or recognizable.

In FIG. 3, a device 300 is shown which is designed to produce one of the above-mentioned identity, value or security documents 100. Using this device 300, the method for production is also explained in more detail.

In the present case, the device 300 has a gathering station 316 at which a plurality of the polymer layers 110 are gathered. By means of a transport device 308, the assembled stack of polymer layers 110 is fed in a transport direction 310 to a lamination device 302 of the device 300. All devices of the device 300 are preferably aligned inline with one another, so that the transport device 308 can be formed as a linear transport device 308, which means that it is significantly faster with a transport device that is not linearly adjustable. The lamination device 302 comprises laminating sheets, between which the stack becomes a monolithic one under the action of heat and pressure

Polymer composite layer 114 is laminated. Optionally, a printing device 314 is downstream of the lamination device 302, which is designed to provide a surface 104, 106 of the polymer layer composite 114 with printing, in particular with a security feature 500. Of course, the

Printing device 314 also of the lamination device 302 or also the

Gathering station 316 can be upstream, so that one of the intermediate polymer layers 110 can be provided with printing. Of the

Polymer layer composite 114 can be cut to size or punched out by means of a cutting device if this composite is not yet the desired

Has dimensions for the identification, value or security document 100 to be produced. But there is also the possibility that the layer composite is already after has the desired dimensions after lamination. Then there is the base body 102 on which the varnish that can be written on with the colorant, which is suitable for documents, is applied by means of a pad printing device 200. This pad printing device 200 will be discussed in greater detail below. After the application of the writable varnish, the ID, value or security document 100 is fed to a downstream drying device 304 which comprises a light source 306 which is preferably designed to emit electromagnetic radiation from the ultraviolet spectral range (UV drying). After the lacquer has dried, the identification, value or security document 100 produced in this way is preferably collected at a collection point 312 and then removed from the device 300.

The pad printing device 200 is explained in more detail with reference to FIG. 4 in a view perpendicular to the transport direction 310 in the device 300. This includes a paint container 212 in which the paint of the

Labeling field 108 is kept ready. The paint can be introduced into an engraving 202 of a cliché 204 by means of an ink application unit 206 (A).

Excess paint is removed from the cliché 204 by means of a doctor blade 208 (B) before a pressure pad 210 mounted on a manipulator sucks up the paint located in the engraving 202 and transfers it to the surface 104, 106 of the base body 102 (C). For printing another ID card, value card or

Security document 100, the steps explained above are carried out again.

In summary, it can be stated that the identification, value or security document 100 according to the invention can be produced particularly efficiently due to the printing technology attachment or application of the

Inscription field 108. The method according to the invention also allows the cycle time in the production of a plurality of identity cards, value cards or

Reduce security documents 100. The device 300 according to the invention is also distinguished by a significant cycle time reduction. REFERENCE LIST
