Description

The invention relates to a method for identifying a data page, in particular for a value and / or security document, and a device by which a data page is identified.

To increase the security against forgery of value and / or security documents, data pages are provided with personalization data and / or security features. Such a data page usually consists of several layers which are connected to one another by lamination. At least the outer layers consist of a thermoplastic elastomer. For a data page, a middle layer, which can also consist of paper, is printed, for example, with a portrait of the document holder. The printed transparent layer is protected from manipulation by the outer transparent cover layers of the data carrier. The data page is thus personalized during its production and integrated into a value and / or security document.

However, there are requirements to provide such a data page as a blank in a value and / or security document so that decentralized personalization can take place. Such decentralized personalization can be carried out by subsequent laser irradiation, a layer adjacent to the cover layer being written on and blackened. As a result, characteristics such as a font or an image can only be generated in black and white.

From the DE 10 2015 202 252 A1 a method for decentralized individualization of value or security documents is known. It is provided that at least one non-individualizing security print is provided on at least one of the two outer sides of the document and that this is overlapped with an individualizing security feature in the same printing plane. The printing ink or printing ink for this security feature is printed with a digital printing process on overlay layers of the document body, which are made of polycarbonate.

From the DE 195 31 740 A1 a piezoelectric ink jet head is known, through which a printing ink or printing ink is output on a medium. Such an ink jet head is used, for example, in copiers or fax machines.

From the DE 10 208 012 437 A1 a method for producing a security or value document with protected personalized information is also known. A polymer layer base composite comprises at least one polymer cover layer, each of which has a printing substrate layer. This printing substrate layer is receptive to a diffusible colorant. After the diffusible colorants have been applied, this diffuses into the printing substrate layer of the polymer cover layer.

From the EP 2 580 065 B1 a method for decentralized personalization of a data page is known, in which a colored portrait of the document holder is produced. This is desirable because it further increases the security against forgery. This colored portrait is achieved by laser inscription, in which areas of a colored preprint on the data page are processed with laser radiation on a layer adjacent to a transparent layer, so that the colored preprint is locally covered with shades of gray and the remaining ones that are not treated by the laser radiation Color areas give a colored impression. The flexibility in the design of the labeling in the case of decentralized personalization of such a data page is restricted with such a method. There is also a low level of color saturation.

From the DE 602 10 063 C2 a needleless injection device is known in which particles are mixed into a gas flow and discharged together with the gas flow. The gas flow with the particles is introduced into a tissue of a vertebrate subject, which enables a needleless injection of particles into the tissue.

The invention is based on the object of proposing a method for identifying a data page, in particular for a value and / or security document, by means of which carriers of dyes are introduced into the data page for their identification. Furthermore, the invention is based on the object of proposing an injection device by means of which the identification of such a data page is made possible.

This object is achieved by a method in which the data side comprises a data carrier which comprises at least one carrier layer and at least one outer cover layer connected to the carrier layer, with a dye or, respectively, carrier through a nozzle of an injection device which is aligned with the cover layer of the data carrier Ink carriers are output accelerated and penetrate the at least one top layer and penetrate into an underlying layer. This enables simple and tamper-proof, decentralized personalization. By marking the data page, in which the carriers of dyes penetrate the at least one outer cover layer and into the layer below penetration, an additional application of a further layer on the cover layer is no longer necessary to protect the marking printed on the cover layer. In addition, the security against counterfeiting is increased since the carriers of dyes that have penetrated into the at least one cover layer and the underlying layer can no longer be detached. At the same time, a detachment of the cover layer from the layer below can be recognized. Adequate saturation of the individual indicators can also be made possible.

The carriers of the dyes discharged through the nozzle by the injection device can be supplied to the injection device in liquid form.

The carriers of the dyes can be supplied as liquid preparations or as a solid powder. Liquid preparations can consist of organic dyes which are dissolved in an organic solvent or solvent mixture. Examples of organic dyes are carbonyl dyes, quinones, indigoid dyes, quinacridones, but also cyanine dyes such as di- and triphenylmethane dyes and azo dyes.

Depending on the material properties, saturated unbranched and branched hydrocarbons, esters, ketones, glycol ethers etc. are used as solvents. An example could be the liquid preparation of a solution of an amino-anthraquinone dye "Solvent Blue 35" in methyl-ethyl-ketone (2-butanone), which wets or even solves the surface of the data page to be printed.

Furthermore, the carriers of dyes can alternatively be supplied in solid form to the injection device. For example, powdered pigments can be added. These can also penetrate into the cover layer and be anchored in it to identify the data page.

The solid supports of the dyes can be provided, for example, solid colored supports, such as indigo, quinacridone (for magenta). So that the color pigments do not shatter on the rather hard card surface, it may be advisable to impregnate microcelolites with organic dyes and to inject these ceramic vehicles onto the card surface.

Furthermore, the ink carriers are preferably provided in different colors and successively fed to the injection device and output to identify the data page. In a decentralized personalization, this enables the introduction of a colored marking, in particular personalization, in a simple manner. For example, a portrait of the document holder can be included in color. Additional characteristics, such as the colors of a nation or other color samples, can also be added subsequently to identify the data page.

The ink carriers are preferably dispensed by the injection device at a pressure of 50 to 500 bar. This ensures that the individual ink carriers penetrate at least into the outer cover layer of the data page. External application is not intended.

The ink carriers are preferably provided with a size that is smaller than 50 μm (d90). This also enables the production of a graphic image with a high resolution and / or a high color saturation.

Furthermore, a data page is preferably marked with at least one outer cover layer with a thickness of at least 1 μm, preferably of at least 5 μm. The thickness of the cover layer is preferably less than 100 μm, in particular less than 50 μm. Due to the mutual adaptation of the thickness of the at least one outer cover layer by the ink carrier, the ink carrier applied by the injection device can penetrate only into the outer cover layer or into the outer cover layer and into at least one underlying cover layer and / or carrier layer.

The data page preferably comprises at least one outer cover layer made of a thermoplastic elastomer, in particular of polycarbonate, polypropylene, polyethylene, polyethylene terephthalate.

In the disclosures DE 10 2010 044 025 . DE 10 2012 200 235 and DE 10 2012 222 742 Functional materials with controllable networks are described. With appropriate parameters, such materials enable the dyes to penetrate easily and change their properties when the corresponding parameters change.

Furthermore, the outer cover layer of the data carrier is heated. This can reduce the stability of the crosslinking of the outer cover layer and facilitate the penetration of the carrier of dyes.

The outer cover layer is preferably heated by supplying hot air. In this way, heating of the outer cover layer for specific introduction of the carrier of dyes can also be achieved in some areas.

For decentralized personalization, the data page is preferably provided as a blank card in order to personalize this blank card decentrally by the injection device, in particular to personalize it in color. Such a blank card consists of the at least one carrier layer and at least one outer cover layer, which are at least free of information regarding the document holder. This blank card can already contain security features or country-specific indicators. Thanks to the decentralized personalization, the portrait of the document holder as well as the name and data of the document holder can be brought into an ICAO zone according to the ICAO standard.

The carriers of the dyes for identifying the data page are preferably output by means of a drive device of the injection device, which controls a linear, periodic movement of a working cylinder. In this way, a targeted penetration of the ink carrier into the at least one outer cover layer can be controlled.

The ink carriers are preferably fed to the pressure chamber via at least one outlet. This enables a simple change in the color and / or type of the color carrier for the production of a colored marking in particular.

A Venturi or Laval nozzle is preferably positioned on the outlet side of the pressure chamber. As a result, the ink carriers can be additionally accelerated in order to penetrate securely into the at least one outer cover layer of the data page. Alternatively or additionally, the pressure chamber of the injection device is supplied with a gas stream for introducing the ink carrier into the at least one outer layer of the data side. The color carriers can be mixed in the gas stream and fed to the data page.

The object on which the invention is based is further achieved by an injection device which has a drive device which controls a working cylinder in a pressure chamber, which is assigned to a connection for supplying carriers of dyes and with a nozzle arranged on the outlet side of the pressure chamber. The connection for feeding the ink carrier is provided downstream of the nozzle arranged on the outlet side of the pressure chamber. The working pressure generated in the pressure chamber, in particular gas pressure of the carrier gas, accelerates the carrier gas through the nozzle. The ink carriers are introduced into this accelerated working flow of the carrier gas and are fed specifically to the data side.

Alternatively, the connection for supplying the ink carrier is provided in the pressure chamber of the drive device.

With this injection device, ink carriers can thus be accelerated in a targeted manner and output with high pressure in order to penetrate the outermost layer of the data page and at least penetrate into the layer below. This also makes manipulation difficult, since an exchange of the cover layer is immediately visible.

The drive device is preferably formed by a piezo drive or a voice coil drive. These can be controlled in a targeted manner and at high frequencies in order to generate periodic movements of a printing cylinder. A compact drive device can thereby be created, by means of which high pressures for discharging the ink carriers are also generated at the same time.
