Abstract

Secured document in the form of a card consisting of a laminate of polycarbonate layers with permanent markings, personalized markings and a lenticular composite image compatible with lenticular lenses shaped in the external layer of the card. The lenticular composite image (307L) is personalized and multi-colored, the personalized lenticular composite image being applied to a layer (304) that is farther from the outer layer (301) with the lenticular lenses (306) than the layer (303) containing the fixed indicia ( 308).

Description

Pattern description

The subject of the utility model is the security document.

Security documents are known in the form of cards made of a laminate of several layers. These documents are marked with various types of markings, such as fixed texts (document name, document publisher's name) on the offset-printed sub-printing layer, or personalized markings (data of the document holder in text form, for example name, surname, address, or in graphic form, for example a photo face) printed using ink-jet technology on the underprint layer or on a separate layer. The markings can also cover different types of dates, such as the date of birth of the holder of the document, vesting date, and expiry date of the document. Preferably, the indicia are applied to one document by several different techniques, which makes it difficult to counterfeit the document. For this purpose, for example, secured inks, special ink additives or various types of lasers are used, causing different color and organoleptic effects on the surface of the card. The documents also use security features containing images that change depending on the viewing angle. One of this type of security is the so-called lenticular effect, consisting of a set of parallel and adjacent lenticular lenses, under which there is a properly prepared lenticular image. The lenticular image may be an image composed of several, for example two, images, one of which is visible through the lenticular lens from one viewing angle and the other is visible from a different viewing angle.

To ensure the appropriate usability of the document, it is important to use the optimal number of security features - that is, one that will ensure an appropriate level of security, but will not reduce the legibility of the document and the comfort of using it.

Security documents are known in the form of cards that are a laminate of plastic layers, one of the layers having fixed markings offset by means of an offset technique, including, inter alia, a lenticular composite image that is compatible with lenticular lenses formed in at least one outer layer of the card. For example, such a document may be an identity card, and a lenticular composite image may show different variants of the representation of the flag of the country that issued the ID card. This image is constant for all documents of this type.

It would be desirable to develop a security document with a lenticular composite image with a security level superior to that of prior art documents.

The object of the utility model is a document secured in the form of a card which is a laminate of polycarbonate layers, on which permanent markings are applied, personalized markings 1 lenticular composite image compatible with lenticular lenses shaped in the outer layer of the card, characterized by the fact that the lenticular composite image is personalized and multicolored , wherein the personalized lenticular composite image is applied to a layer that is farther from the outer layer with the lenticular lenses than the layer containing the solid indicia.

Preferably, the lenticular lenses are formed on a portion of the outer surface of the card smaller in size than the entire outer surface of the card.

The use of a multi-color lenticular composite image in a document that is personalized is an effective security feature for the document, thereby making it difficult to counterfeit.

The subject of the utility model is presented in the examples in the drawing, where:

Fig. 1 shows schematically the document in top view.

Fig. 2 is a schematic representation of a card layer constituting a utility model document.

The document secured according to the utility model is in the form of a plastic card 100 constituting a laminate of several polycarbonate layers. A document, which all layers are made of polycarbonate, is highly durable and is difficult to counterfeit as its layers permanently integrate with each other during lamination.

Fig. 1 shows schematically the document in top view. The document has the constants 108, i.e. the so-called overprint, such as background 108A, names of information fields 108B

Claims (2)

and document name 108C. The document also has personalized markings 107 such as picture 107A or the values of information fields 107B. Fig. 2 is a schematic representation of a card layer constituting a utility model document. The utility model card 100 is comprised of a laminate of several polycarbonate layers 301-305 including outer layers 301,305 and inner layers 302-304. To make the drawing easier to read, the layers are shown spaced apart and not to scale. The outer layers 301, 305 are preferably transparent to show the images thereunder in the form of personalized indicia 307 and solid indicia 308. Inner layer 304 includes solid indicia 308 such as background 108A, information field name 108B, document name 108C or other indicia. Preferably, the indicia 308 are offset-printed. Another inner layer 302 includes personalized indicia 307 in graphic or text form, such as photo 107A, information field values 107B, and others. The personalized markings 307 are made by ink-jet technology before lamination of the card or by laser engraving after lamination of the card (in this case, they are present in the volume of layer 302 and not as a coating on layer 302, as indicated in Fig. 2 for simplicity). Between layers 302 and 304 there may be another layer 303 containing other images, integrated circuits, or other security features. The structure of the card is not limited to the layer arrangement shown in the embodiment, and may relate to arbitrarily stacked layers including the indicia 307, 308. The card comprises on an inner layer 304 which is further from the outer layer 301 with lenticular lenses 306 than the layer 303 containing permanent markings 308, lenticular composite image 307L. Over the lenticular composite image 307L, the outer layer 301 is formed with lenticular lenses 306 compatible with this image. The lenticular lenses 306 cause the user to see its individual component images depending on the viewing angle at the composite image 307L. The remaining personalization elements 307 may be applied to layer 302 which is closer to layer 301 with leticular lenses 306 than layer 303. It is important then that the images 307, 308 contain empty unprinted fields revealing image 307L beneath them, so that image 307L is was visible through the lenticular lenses 306. The lenticular lenses 306 are positioned only over a portion of the top surface of the card, that is, only in the area where the lenticular image occurs. In a utility model solution, at least a portion of the lenticular composite image 307L is personalized, i.e. its content is specific to the card. The personalized lenticular composite image 307L can be multicolored and printed on layer 304 using ink-jet technology. Solvent ink, in particular eco-solvent ink or solvent-free ink, is particularly suitable for printing a personalized lenticular complex image 307L. For example, a personalized lenticular composite image 307L may include component images specifying different strings (for example, the name of the document holder, date of birth, and document issue date) or component images specifying different graphic images (for example, left and right pictures of the document holder. ). Security claims 1. A security document in the form of a card which is a laminate of polycarbonate layers with permanent markings, personalized markings and a lenticular composite image compatible with lenticular lenses shaped in the outer layer of the card, characterized in that the lenticular composite image (307L) is personalized and multi-color, wherein the personalized lenticular composite image is applied to a layer (304) that is further away from the outer layer (301) with lenticular lenses (306) than the layer (303) containing the fixed indicia (308). 2. The security document according to claim 1 The method of claim 1, wherein the lenticular lenses (306) are formed on a portion of the outer surface (301) of the card smaller in size than the entire outer surface (301) of the card.
