Description
Proti ponarejanju in/ali prenarejanju zaščiten dokument ter postopek izdelave tovrstnega dokumentaProtected document and / or falsified document and the process of making such document
Izum spada na področje tiskarstva, še zlasti pa se nanaša na izdelavo listin, izkaznic in podobnih proti ponarejanju in/ali prenarejanju karseda zaščitenih dokumentov.The invention relates to the field of printing, and in particular relates to the production of documents, cards and the like against the forgery and / or forgery of as many protected documents as possible.
Pri tem je izum osnovan na problemu, kako zasnovati proti ponarejanju in/ali prenarejanju zaščiten dokument, pri katerem bo kot eden od zaščitnih elementov uporabljena takoimenovana skrita oz. latentna slika, ki bo po izbiri zaznavna tudi na otip, vsekakor pa pod določenim kotom vidna pri naravni ali umetni dnevni svetlobi in jo bo mogoče z zahtevano natančnostjo izdelati na razmeroma preprost način ter pri tem po potrebi zagotoviti, da bo med uporabo dokumenta zaščitena proti poškodbam, hkrati pa naj bi bila zahvaljujoč načinu izvedbe omenjene skrite slike proti poškodbam in prenarejanju varovana tudi pred tem pripravljena, z vsakokrat potrebnimi podatki in drugimi zaščitnimi elementi opremljena vsakokratna podatkovna stran dokumenta.In doing so, the invention is based on the problem of how to design a security document that uses the so-called hidden or non-counterfeit document as one of the security features. a latent image that will optionally be palpable, but in any case visible from natural or artificial daylight at a certain angle, and can be produced with the required precision in a relatively simple manner, ensuring that it is protected against use when using the document In the meantime, thanks to the method of performing said hidden image against damage and tampering, the previously prepared data sheet, together with the necessary data and other security features, should be equipped with the respective data page of the document.
Ena izmed možnosti zaščite dokumentov proti ponarejanju je opremljanje le-teh z optično spremenljivimi grafičnimi elementi. Tako je v WO 93/22146 oz. PCT/US93/03697 (TRAPLETTI, Claude) opisan postopek tiskanja in zaščite dokumenta z optično spremenljivo sliko na površini. V omenjenem postopku je uporabljena tehnika takoimenovanega intaglio tiska, ki omogoča doseganje velike natančnosti odtisa, sama zasnova optično spremenljive slike pa omogoča, da je slika vidna zgolj v primeru, če svetloba nanjo pada pod določenimi koti. Kadar svetloba pada nanjo npr. pravokotno glede na ravnino dokumenta, je slika namreč nevidna. Tak način zaščite je učinkovit v primeru preprečitve zlorab oz. ponarejanja s pomočjo fotokopiranja, ker je pač pod kotom osvetlitve pri fotokopiranju omenjeni zaščitni element neviden in zato na kopiji preprosto izgine.One option to protect documents against counterfeiting is to equip them with optically variable graphic elements. Thus, in WO 93/22146 respectively. PCT / US93 / 03697 (TRAPLETTI, Claude) outlines the process of printing and protecting a document with an optically variable surface image. The technique uses the so-called intaglio printing technique, which enables high accuracy of the print, and the design of the optically variable image allows the image to be visible only if the light falls on it at certain angles. When light falls on it, e.g. orthogonal to the plane of the document, the image is invisible. This type of protection is effective in preventing abuse or counterfeiting by means of photocopying, since, at the angle of illumination, the photocopying element is invisible and therefore simply disappears on the copy.
Nadaljnjo zvrst optično spremenljive slike je v skladu z rešitvijo po WO 00/76784 oz. PCT/AU00/00629 (SECURENCY ΡΤΥ. LTD.) možno dobiti na ta način, da se preko ustreznega substrata nanese gladko plast z visoko reflektivnostjo, na katero se spet s tehniko intaglio tiska na določenih mestih nanese razmeroma debelo plast tiskarske barve oz. črnila ustrezne sestave. V tem primeru se med osvetljevanjem dokumenta pod različnimi koti barva odtisa spreminja, zato gre spet predvsem za zaščito dokumenta proti fotokopiranju.A further type of optically variable image is in accordance with the WO 00/76784 solution. PCT / AU00 / 00629 (SECURENCY LTD. LTD.) Can be obtained in such a way that a smooth, high-reflective layer is applied over the appropriate substrate, and again a relatively thick layer of printing ink or, in particular, is applied to the intaglio printing technique. inks of appropriate composition. In this case, when the document is illuminated at different angles, the color of the print changes, so again it is primarily to protect the document against photocopying.
V evropski patentni prijavi EP 0 540 455 Al (Gili Picoy, Palmira) je bil razložen postopek priprave tiskovin z optičnimi učinki. Pri tem se v prvem koraku eno od površin lista papirja na običajen način potiska, nakar se v drugem koraku preko potiskane površine nanese smolo, termoplastičen lak ali drugo transparentno gradivo, kar zagotavlja impregnacijo omenjenega papirja. Zatem se v tretjem koraku s pomočjo temperature in pritiska vsaj določeno območje tako obdelane površine opremi z ustrezno gravuro, ki omogoča doseganje želenih optičnih učinkov. Temu sledi razrez na želene izmere posamičnih delov. Omenjeno smolo je možno polimerizirati s pomočjo ultravijoličnih žarkov, kar se vrši neposredno po izvedbi gravure. Postopek je nemara primeren za uporabo drugih zaščitnih elementiv, tiskanje skrite oz. latentne slike pa ni možno.The European patent application EP 0 540 455 Al (Gili Picoy, Palmira) explained the process of preparing printed matter with optical effects. In the first step, one of the surfaces of the sheet of paper is normally pressed, and in the second step a resin, thermoplastic varnish or other transparent material is applied over the printed surface, which ensures the impregnation of said paper. Then, in the third step, the temperature and pressure of at least a certain area of the surface so treated is equipped with an appropriate engraving to achieve the desired optical effects. This is followed by cutting into the desired dimensions of the individual parts. The resin can be polymerized by means of ultraviolet rays, which is done immediately after engraving. The process may not be suitable for the use of other protective elements, printing hidden or. however, no latent image is possible.
Nadalje je v W0 90/12694 oz. PCT/AU90/00167 (COMMONWEALTH OF AUSTRALLA; Department of Foreign Affairs & Trade) opisana izdelava zaščitne slike, pri čemer se sliko izdela s tiskanjem na sloj visokotemperatumega lepila, ki se ga nanese na sloj transparentnega medija. Tiskanje se vrši s pomočjo spojin na karbonski osnovi, ki v stiku s plastjo lepila ne tečejo. Sestav transparentnega medija, visokotemperatumega lepila in slike se zatem s segrevanjem na primemo temperaturo nalepi na substrat, s čimer dobijo laminat iz transparentnega medija in substrata. Med lepljenjem naj bi se slika ne poškodovala in naj bi zato ostala dobro vidna skozi transparentni medij. Kot transparentni medij je mogoče uporabiti poliestrsko smolo ali plast iz drobcev stekla, dispergiranih v lepilo. Če želijo omenjeni sestav še ojačiti, na substrat pritrdijo še vsaj eno dodatno plast. Omenjeni način temelji na prenosu barve s polepljenega transparentnega medija na substrat, pri čemer gre za visokotemperatumo lepilo, ki se med lepljenjem tali. Povsod v tistih območjih, kjer je preko sloja lepila nanešena barva, je adhezivnost lepila proti substratu vprašljiva, kar lahko privede do razslojevanja. Pri nanašanju barvil na površino pri dovolj visoki temperaturi in ustreznem pritisku nadalje pogosto obstoji možnost takoimenovanih migracij, t.j. pojava, ko delci barvila migrirajo tudi v območja, ki za to sicer niso predvidena. Posledice so vidne kot lise ali razmazanost slike. Za izvedbo takoimenovane skrite slike, kjer je zahtevana izjemna natančnost slike, je tak proces torej v osnovi neprimeren.Further, in W0 90/12694 respectively. PCT / AU90 / 00167 (COMMONWEALTH OF AUSTRALLA; Department of Foreign Affairs & Trade) described the manufacture of a protective image, the image being produced by printing on a layer of high-temperature adhesive applied to a layer of transparent medium. Printing is done using carbon-based compounds that do not flow in contact with the adhesive layer. The composition of the transparent medium, the high-temperature adhesive and the image is then glued to the substrate by heating to a suitable temperature, thereby obtaining a laminate from the transparent medium and the substrate. During bonding, the image should not be damaged and should therefore remain clearly visible through transparent media. As a transparent medium, a polyester resin or a layer of fragments of glass dispersed in the adhesive can be used. In order to further strengthen said composition, at least one additional layer is attached to the substrate. This method is based on the transfer of color from the translucent transparent medium to the substrate, which is a high-temperature adhesive that melts during bonding. In all areas where paint is applied over the adhesive layer, adhesive adhesive to the substrate is questionable, which can lead to delamination. In addition, the application of dyes to the surface at a sufficiently high temperature and appropriate pressure also often leads to the possibility of so-called migrations, i.e. the occurrence of when the dye particles migrate to areas not otherwise provided for. The consequences are seen as spots or smudges on the image. Therefore, the implementation of the so-called hidden image, where extreme precision of the image is required, is fundamentally inappropriate.
Nadalje je v WO 93/22147 oz. PCT/JP93/00596 (HITACHI MAXELL, LTD.) opisan nosilec latentne slike skupaj s postopkom njegove izdelave in čitalnikom latentne slike. Pri tem gre za latentno, t.j. prikrito sliko, kije nanešena na podatkovnem nosilcu in sestoji iz fosfornih delcev, ki so dispergirani in nameščeni na substratu. Pri osvetlitvi s svetlobo določene valovne dolžine znaša luminiscenca omenjenih fosfornih delcev vsaj 20%, zaradi česar omenjena prikrita slika postane vidna. Kot rečeno, je za identifikacijo prikrite slike potrebna osvetlitev dokumenta s svetlobo posebne vrste, kar terja uporabo posebnih pripomočkov. To potrebo po osvetljevanju s posebno svetlobo gre v kontekstu uvodoma zastavljenega problema šteti kot pomanjkljivost.Further, in WO 93/22147, respectively. PCT / JP93 / 00596 (HITACHI MAXELL, LTD.) The latent image carrier described along with its manufacturing process and the latent image reader. This is latent, i.e. a covert image applied to a data carrier consisting of phosphorus particles dispersed and mounted on a substrate. In the case of illumination with a certain wavelength, the luminescence of said phosphorus particles is at least 20%, which makes the said obscure image visible. That being said, document identification with a special type of light is required to identify the hidden image, which requires the use of special aids. This need for illumination with special light is considered to be a disadvantage in the context of the problem posed initially.
Še nadalje je iz WO 95/23698 oz. PCT/NL95/00080 (SALLMETAL B.V.) znan postopek laminiranja večplastnega transparentnega filma, potiskanega na osnovi tkzv. inkjet tehnike, namreč z brizganjem črnila na ustrezen nosilec. Opisan je tudi laminat, ki je dobljen po tem postopku. Ta rešitev temelji na potrebi, da bi se izognili že v predhodnem patentnem dokumentu omenjenemu transfernemu nanašanju slike, namreč prenosu le-te z neke vmesne plasti, npr. silikoniziranega papirja, na nosilec, ki je zmožen sprejeti barvo oz. črnilo, pri čemer se po odstranitvi te vmesne plasti potiskan nosilec združi z zaščitno folijo, tako da se ju medsebojno zlepi, pri tem pa se slika nahaja med omenjenima nosilcem in zaščitno folijo. Z eliminacijo prenosa slike naj bi bilo možno izboljšati kakovost slike, hkrati pa naj bi bil izboljšan proces tudi bolj preprost. V kontekstu te reštve laminat sestoji iz nosilnega sloja, slike, lepilnega sloja ter iz transparentne pokrivne folije, skozi katero je slika vidna. Postopek v skladu z nazadnje obravnavanim virom naj bi potekal na ta način, da bi v prvem koraku pripravili transparentno pokrivno folijo, preko katere je nanešen lepilni sloj, preko slednjega pa še sloj, ki absorbira črnilo. Zatem se na nazadnje omenjeni sloj s pomočjo inkjet tiskalnika, t.j. z brizganjem črnila, izdela sliko, kije glede na nosilni sloj invertirana, t.j. zrcalno obrnjena. Nato se pripravi nosilec, ki sestoji npr. iz papirja ali iz umetne mase v obliki folije ali toge plošče, nakar se pokrivno folijo, na kateri se nahaja slika, poveže z nosilnim slojem, in sicer tako, da se ta nosilni sloj prilepi na lepilno folijo s pomočjo lepilnega sloja, tako daje slika nameščena med nosilnim slojem in pokrivno folijo. Pri tem se povezovanje pokrivne folije z nosilnim slojem prednostno vrši s stiskanjem med valji, pri čemer se na osnovi primemo visoke temperature in pritiska aktivira lepilo. Če je nosilec izveden iz transparentnega gradiva, je dobljeni laminat lahko transparentnen. Nosilec je lahko tudi lesena ali plastična pošča debeline 10 ali 20 mm, pri čemer znaša debelina pokrivne plasti približno 100 pm, debelini lepilnega sloja in sloja za absoborbcijo črnila pa znašata vsga nekaj pm. Lepljenje pokrivne folije z nosilcem tudi v tem primeru poteka preko lepilnega sloja, ki pa je prevlečen s slojem za absorpcijo črnila ter v območju slike tudi s črnilom. Stik med lepilnim slojem in nosilcem je torej tudi v tem primeru obremenjen s prisotnostjo drugih snovi, ki imajo na sam proces lepljenja nedvomno lahko bolj ali manj neugoden vpliv. Čim debelejši je sloj za absorpcijo črnila, tem bolj neugoden pa je lahko vpliv te plasti na proces lepljenja. Po drugi strani tanjšanje te plasti lahko okrni možnost absorbcije črnila, kar ima za posledico razmazanost slike, hkrati pa se poveča možnost migracije delcev črnila pod vplivom temperature in pritiska. Na ta način je povsem nemogoče zadostiti zahtevam, ki jih narekuje izdelava skrite slike na dokument, ki naj bi bil zaščiten proti ponarejanju oz. prenarejanju.It is further from WO 95/23698 respectively. PCT / NL95 / 00080 (SALLMETAL B.V.) a known process for laminating a multilayer transparent film printed on a so-called. inkjet techniques, namely by spraying ink onto a suitable carrier. The laminate obtained by this process is also described. This solution is based on the need to avoid in the previous patent document the aforementioned transfer of the image, namely, transferring it from an intermediate layer, e.g. siliconized paper, on a carrier capable of accepting color or. ink, whereupon after removal of this intermediate layer, the printed support is combined with the protective film so that they are glued to each other, the image being between said media and the protective film. By eliminating image transfer, it is possible to improve the quality of the image, while making the process even simpler. In the context of this arrangement, the laminate consists of a carrier layer, an image, an adhesive layer and a transparent cover film through which the image is visible. The process according to the last discussed source should be carried out in such a way that in the first step a transparent cover film is applied over which an adhesive layer is applied, and an ink absorbing layer is applied over the latter. Then, to the last mentioned layer, use an inkjet printer, i.e. by ink spraying, produces an image that is inverted with respect to the carrier layer, i.e. mirror-inverted. Next, a carrier is prepared consisting e.g. of paper or plastic in the form of a foil or a rigid plate, after which the cover film on which the image is attached is bonded to the carrier layer by adhering the carrier layer to the adhesive film by means of an adhesive layer so that the image placed between the carrier layer and the cover film. In this connection, the bonding of the cover film to the carrier layer is preferably done by pressing between the cylinders, whereby the adhesive is activated on the basis of high temperatures and pressure. If the support is made of transparent material, the resulting laminate may be transparent. The carrier can also be a 10 or 20 mm thick wooden or plastic sack, with a coating thickness of about 100 pm and an adhesive and ink absorbent thickness of only a few pm. In this case, too, the adhesive film is bonded to the carrier by means of an adhesive layer, which is coated with an ink absorption layer and ink in the image area. In this case, the contact between the adhesive layer and the carrier is also burdened by the presence of other substances, which can undoubtedly have a more or less unfavorable effect on the bonding process. The thicker the ink absorption layer is, the more unfavorable the impact of this layer can be on the bonding process. On the other hand, thinning this layer may impair the possibility of ink absorption, resulting in smudged images, while increasing the possibility of migration of ink particles under the influence of temperature and pressure. In this way, it is completely impossible to meet the requirements dictated by the production of a hidden image on a document that is supposed to be anti-counterfeiting or. reorder.

Over said surface 1, a multi-layer coating 2 is applied to said surface 11, which generally consists of an adhesive layer 20 as well as a first transparent coating layer 21 and a second transparent coating layer 22 and a protective coating layer 23 colors.
Na sl. 1 je prikazan prvi primer izvedbe dokumenta po izumu, pri katerem je omenjena večslojna obloga 2 tako izvedena, da je na za zaščito predvideno stran 1 vsakokratnega dokumenta prilepljena s pomočjo svojega - gledano v smeri proti dokumentu - najbolj zunanjega lepilnega sloja 20, preko katerega je nanešen sloj 23 zaščitne barve. Preko slednjega je nanešen skrito sliko 4 obsegajoč drugi sloj 22 transparentnega premaza, preko katerega je nanešen prvi sloj 21 transparentnega premaza. Pred nanašanjem na pripadajočo stran 1 dokumenta so omenjeni sloji 20, 21, 22, 23 obloge 2 nanešeni na silikonizirano nosilno folijo 3, kije po zlepljenju obloge 2 z za zaščito predvideno stranjo 1 dokumenta odstranljiva.In FIG. 1 shows a first embodiment of a document according to the invention, in which said multilayer lining 2 is so arranged that the page 1 of the respective document is affixed to the security provided by its outer glue layer 20, through which it is viewed in the direction of the document. applied coat 23 of protective paint. Through the latter, a hidden picture 4 is applied, comprising a second transparent coating layer 22, through which a first transparent coating layer 21 is applied. Prior to application to the corresponding page 1 of the document, said layers 20, 21, 22, 23 of the liner 2 are applied to a siliconized carrier film 3 which, after adhesion of the liner 2 with the protective page 1 of the document, is removable.
Na sl. 1 je na levi strani prikazana nosilna folija 3, kije na eni svoji strani 30 opremljena s silikonsko plastjo 31. Preko slednje je nanešen prvi sloj 21 transparentnega premaza, preko slednjega drugi sloj 22 transparentnega premaza s skrito oz. latentno sliko 4, preko tega drugega sloja 22 lakaje nanešen sloj 23 zaščitne barve, preko slednjega pa še lepilni sloj 20. Kot rečeno, omenjeni sloji 20, 21, 22, 23 tvorijo večslojno oblogo 2, ki je s pomočjo lepilnega sloja 20 namestljiva na vsakokrat za zaščito predvideno stran 1 dokumenta, hkrati pa je z nje zahvaljujoč silikonskemu sloju 31 odstranljiva omenjena nosilna folija 3.In FIG. 1 shows on the left side a carrier foil 3, which is provided with a silicone layer on one side 30 thereof. The first layer of transparent coating 21 is applied over the latter, and the second layer 22 of the transparent coating with concealed or transparent coating is applied over the latter. latent figure 4, through this second layer 22, is applied a protective layer 23 of protective color, and through the latter also an adhesive layer 20. As mentioned, said layers 20, 21, 22, 23 form a multilayer coating 2 which is adjustable by adhesive layer 20. in each case the page 1 of the document provided for protection, and at the same time the said carrier film 3 is removed thanks to the silicone layer 31.
Nanašanje omenjenih slojev 20, 21, 22, 23 kot tudi silikonskega sloja 31 se smiselno vrši v okviru postopka izdelave dokumenta po izumu, ki obsega spodaj navedene korake.The application of said layers 20, 21, 22, 23 as well as the silicone layer 31 is conveniently carried out in the process of producing a document according to the invention, comprising the steps below.
V prvem koraku se pripravi nosilno folijo 3, ki je vsaj na eni strani 30 silikonizirana oz. prevlečena s silikonskim slojem 31, namreč s slojem iz vsakokrat izbrane snovi, ki pripada skupini spojin na osnovi silikonov, ki ustrezajo v nadaljevanju opisanim zahtevam. Nosilna folija 3 je lahko poliestrska folija debeline približno 30 do 100 pm, preko katere je nanešen silikonski sloj 31 debeline približno 3 pm. Omenjeni silikonski sloj 31 je predviden za začasen prejem preko njega nanešenih dodatnih slojev z možnostjo kasnejše neproblematične odstranitve le-teh. Enake ali podobne folije s silikoniziranim slojem so uporabljive npr. kot nosilci samolepilnih etiket in podobnih izdelkov, ki jih je potrebno kasneje nepoškodovane odstraniti z omenjene folije.In the first step, a carrier film 3 is prepared which is siliconized or at least on one side 30. coated with a silicone layer 31, namely, a layer of a substance selected from each group belonging to the group of silicone-based compounds which meet the requirements described below. The carrier film 3 may be a polyester film about 30 to 100 pm thick, through which a silicone layer 31 about 3 pm thick is applied. Said silicone layer 31 is intended for the temporary receipt of additional layers applied thereon, with the possibility of subsequent unproblematic removal thereof. The same or similar siliconized film films are useful e.g. as holders of self-adhesive labels and similar articles, which must be subsequently removed undamaged from said foil.
V nadaljnjih korakih postopka se na nosilni foliji 3, namreč preko silikoniziranega sloja 31, tvori za laminiranje predvideno oblogo 2, in sicer na ta način, da se v drugem koraku preko silikoniziranega sloja 31 nosilne folije 3 nanese prvi sloj 21 transparentnega premaza, nakar se preko prvega sloja 21 transparentnega premaza nanese drugi sloj 22 transparentnega premaza, pri čemer se na drugi sloj 22 transparentnega premaza prednostno s pomočjo sitotiska natisne zrcalno podobo takoimenovane skrite slike 4, tako da je reliefna invertirana oz. zrcalna podoba skrite oz. latentne slike 4 obrnjena proti omenjenemu prvemu sloju 21 transparentnega premaza, nakar se preko drugega sloja 22 transparentnega premaza nanese sloj 23 zaščitne barve, preko slednjega pa Še sloj 20 lepila. Kot lepilo se izbere primemo termoaktivno lepilo, ki je pri sobni temperaturi oz. temperaturi okolice v trdnem stanju, pri ustrezno povišani temperaturi pa se stali in izkazuje ustrezno adhezivnost proti vsakokratni površini, predvideni za lepljenje. Po realizaciji omenjenih korakov je na nosilni foliji 3 nanešena večslojna 2 obloga, ki je pripravljena za laminiranje. Temu sledeči korak laminiranja se izvrši na ta način, da se folijo 3 oz. na ustrezne izmere obrezan del le-te (kar je na sl. 1 in 2 ponazorjeno z vertikalno črtkano črto pod levim robom za zaščito predvidene strani 1 dokumenta) z na njej nanešeno večslojno oblogo 2 namesti preko vsakokrat razpoložljive površine omenjene strani 1 dokumenta, nakar se vse skupaj, t.j. nosilno folijo 3 z oblogo 2 ter omenjeno podatkovno stran 1 izpostavi povišani temperaturi in zadostnemu pritisku, tako da se z aktiviranjem lepilnega sloja 20 oblogo 2 prilepi na omenjeno podatkovno stran 1, čemur sledi ustrezno razbremenitev v smislu odprave pritiska, zatem pa še ohlajanje.In the further steps of the process, a coating 2 is formed on the carrier film 3, namely through the siliconized layer 31, in such a way that a first transparent coating layer 21 is applied over the siliconized layer 31 of the carrier film 3 in the second step, and then a second transparent coating layer 22 is applied through the first transparent coating layer 21, whereby a mirror image of the so-called hidden image 4 is printed on the second transparent coating layer 22, such that the relief is inverted or. mirror image of the hidden or. latent images 4 facing said first transparent coating layer 21, and then a protective paint layer 23 is applied over the second transparent coating layer 22, and another adhesive layer 20 is applied over the latter. An adhesive is selected as a thermoactive adhesive which is at room temperature or at room temperature. ambient temperature in a solid state, and at a suitably elevated temperature it melts and exhibits adequate adhesion to the surface intended for bonding. Following the implementation of the above-mentioned steps, a multilayer 2 coating is applied to the carrier foil 3, which is ready for laminating. This next laminating step is performed in such a way that the foil is 3 oz. to the appropriate dimensions, the trimmed portion thereof (as illustrated in FIGS. 1 and 2 by the vertically dashed line below the left edge to protect the intended page 1 of the document) is applied to the multilayered coating 2 applied over the surface of the said page 1 of the document available at each time. all together, ie the carrier film 3 with cover 2 and the said data page 1 are exposed to elevated temperature and sufficient pressure, by activating the adhesive layer 20, the coating 2 is glued to said data page 1, followed by a corresponding relief in terms of pressure relief and then cooling.
Zaključni korak obravnavanega postopka obsega zgolj še odstranitev nosilne folije 3 s pripadajočim silikoniziranim slojem 31 z omenjene večslojne laminirane obloge 2, ki s tem ostane neodstranljivo nameščena na vsakokrat razpoložljivi za zaščito predvideni strani 1 dokumenta po izumu.The final step of the present process involves only the removal of the carrier film 3 with its associated siliconized layer 31 from said multilayer laminated liner 2, which thus remains non-removably mounted on each of the pages 1 of the document according to the invention available for protection.
Pri tem je za realizacijo dokumenta po izumu in obenem tudi za izvajanje postopka po izumu kot gradivo prvega sloja 21 transparentnega premaza potrebno izbrati primeren transparentni premaz, npr. ustrezen lak, z zadostno adhezivnostjo proti silikonskemu sloju 31 na nosilni foliji 3, kot tudi s površinsko napetostjo na slikonizirani podlagi, ki omogoča doseganje enakomernega odtisa barve na tovrstni površini. V enakem kontekstu je kot gradivo drugega sloja 22 transparentnega premaza smiselno izbran ustrezen transparenten lak ali drug transparenten premaz, ki je prednostno primeren tudi za izvajanje sicer znane tiskarske tehnike sitotiska, pri čemer je mogoče računati z razmeroma veliko natančnostjo tiska, kjer debeline črt lahko znašajo npr. vsega 0,08 mm ter razmeroma izrazito reliefnostjo tiskane površine, ki je posledica razmeroma velikih debelin tako dobljenih odtiskov za izvedbo skrite oz. latentne slike 4. Spet v okviru taistega konteksta je kot lepilni sloj 20 izbrano transparentno, takoimenovano termoaktivno lepilo, ki je v osnovi lepilo, ki ga je možno na vsakokrat izbrano nosilno površino nanašati v razmeroma tenkem sloju in ki je pri sobni temperaturi trdno in transparentno, aktivirati pa ga je mogoče s taljenjem pri ustrezno povišani temperaturi, pri čemer ob zadostnem pritisku omogoča medsebojno zlepljenje površin, med katerima oz. katerimi se nahaja.In order to realize the document according to the invention and at the same time to carry out the process according to the invention, it is necessary to select a suitable transparent coating, such as the material of the first transparent coating layer 21, e.g. suitable lacquer, with sufficient adhesion to the silicone layer 31 on the carrier foil 3, as well as surface tension on the photonized substrate to allow a uniform color impression on this surface. In the same context, a suitable transparent lacquer or other transparent coating is preferably selected as the material of the second transparent coating layer 22, which is preferably also suitable for the implementation of an otherwise known screen printing technique, which can be calculated with relatively high printing accuracy where the line thicknesses may be e.g. only 0.08 mm and a relatively high relief of the printed surface, which is a consequence of the relatively large thicknesses of the prints thus obtained for concealed or imprinted. 4. Again, in the context of the same context, a transparent, so-called thermoactive adhesive is selected as the adhesive layer 20, which is basically an adhesive that can be applied to the selected carrier surface in a relatively thin layer and which is firmly and transparently at room temperature. , it can be activated by melting at a suitably elevated temperature, with sufficient pressure to allow the surfaces between which or between them to be glued together. which is located.
V drugem primeru izvedbe dokumenta po izumu, ki je prikazan na sl. 2, je omenjena večslojna laminatna obloga 2 tako izvedena, da je na za zaščito predvidene stran 1 vsakokratnega dokumenta prilepljena s pomočjo svojega - gledano v smeri proti dokumentu - najbolj zunanjega lepilnega sloja 20, preko katerega je nameščen skrito sliko 4 obsegajoč drugi sloj 22 transparentnega premaza, preko katerega je nanešen sloj 23 zaščitne barve, preko slednjega pa še prvi sloj 21 transparentnega premaza.In another embodiment of the document of the invention shown in FIG. 2, said multilayer laminate coating 2 is so constructed that it is glued to the document page 1 by means of its outermost adhesive layer 20, through which a hidden picture 4 comprising a second transparent layer 22 is applied. a coating through which a protective paint layer 23 is applied, and through the latter a first transparent coating layer 21.
Na sl. 2 je na levi strani prikazana nosilna folija 3, kije na eni svoji strani 30 opremljena s silikonsko plastjo 31. Preko slednje je nanešen prvi sloj 21 transparentnega premaza, preko slednjega pa sloj 23 zaščitne barve. Preko nazadnje omenjenega sloja 23 je v tem primeru nanešen drugi sloj 22 transparentnega premaza, obsegajoč skrito oz. latentno sliko 4, preko tega drugega sloja 22 transparentnega premaza pa še sloj 20 lepila. Tudi v tem primeru omenjeni sloji 20, 21, 22, 23 tvorijo večslojno oblogo 2, kije s pomočjo svojega lepilnega sloja 20 namestljiva na za zaščito predvideno stran 1 dokumenta, hkrati pa je z nje zahvaljujoč njenemu silikonskemu sloju 31 odstranljiva omenjena nosilna folija 3.In FIG. 2 shows a carrier film 3 on the left side, which is provided with a silicone layer on one side 30 thereof. The first layer of transparent coating 21 is applied over the latter and the protective paint layer 23 over the latter. In this case, a second transparent coating layer 22 is applied over the last-mentioned layer 23 in this case, comprising hidden or non-transparent layers. latent figure 4, and through this second layer 22 of the transparent coating, a layer 20 of adhesive. In this case, said layers 20, 21, 22, 23 also form a multilayer coating 2, which, by means of its adhesive layer 20, can be used to secure the page 1 of the document provided for protection, and thanks to its silicone layer 31, said carrier film 3 is removed.
Nanašanje omenjenih slojev 20, 21, 22, 23 se tudi pri tej različici dokumenta po izumu smiselno vrši v okviru alternativne zasnove postopka izdelave dokumenta po izumu, ki obsega v nadaljevanju opisane korake.Applying said layers 20, 21, 22, 23, even with this version of the document according to the invention, is reasonably carried out within the alternative design of the process of making the document according to the invention, comprising the steps described below.
V prvem koraku se spet pripravi nosilno folijo 3, ki je smiselno lahko povsem enaka kot pri predhodni različici postopka po izumu in torej opremljena s silikonskim slojem 31.In the first step, the carrier foil 3 is again prepared, which can reasonably be exactly the same as in the previous version of the process according to the invention and thus provided with a silicone layer 31.
V nadaljnjih korakih postopka se na nosilni foliji 3, namreč preko silikoniziranega sloja 31, tvori za laminiranje predvideno oblogo 2, in sicer na ta način, da se v drugem koraku preko silikoniziranega sloja 31 nosilne folije 3 nanese prvi sloj 21 transparentnega premaza, nakar se preko tega prvega sloja 21 transparentnega premaza nanese sloj 23 zaščitne barve, nato se preko omenjenega sloja 23 zaščitne barve nanese drugi sloj 22 transparentnega premaza, pri čemer se na drugi sloj 22 transparentnega premaza prednostno v tehniki sitotiska natisne zrcalno podobo takoimenovane skrite slike 4, tako da je reliefna zrcalna oz. invertirana podoba skrite oz. latentne slike 4 obrnjena proti omenjenemu prvemu sloju 21 transparentnega premaza. Zatem se preko drugega sloja 22 transparentnega premaza nanese še sloj 20 lepila. Kot lepilo se izbere primemo termoaktivno lepilo, ki ustreza enakim zahtevam kot v predhodno opisanem primeru izvedbe dokumenta po izumu. Na ta način je po realizaciji omenjenih korakov na nosilni foliji 3 nanešena večslojna 2 obloga, ki je pripravljena za laminiranje. Temu sledeči korak laminiranja se spet izvrši na ta način, da se folijo 3 z na njej nanešeno večslojno oblogo 2 namesti preko vsakokrat razpoložljive za zaščito predvidene strani 1 dokumenta, nakar se vse skupaj, tj. nosilno folijo 3 z oblogo 2 ter omenjeno podatkovno stran 1 izpostavi povišani temperaturi in zadostnemu pritisku, tako da se z aktiviranjem lepilnega sloja 20 oblogo 2 prilepi na omenjeno podatkovno stran 1, čemur sledi razbremenitev v smislu odprave pritiska in zatem ohlajanje. Zaključni korak postopka tudi v tem primeru obsega zgolj še odstranitev nosilne folije 3 s pripadajočim silikoniziranim slojem 31 z omenjene večslojne laminirane obloge 2, ki s tem ostane neodstranljivo nameščena na vsakokrat razpoložljivi strani 1 dokumenta.In the further steps of the process, a coating 2 is formed on the carrier film 3, namely through the siliconized layer 31, in such a way that a first transparent coating layer 21 is applied over the siliconized layer 31 of the carrier film 3 in the second step, and then a first layer of protective paint is applied over this first transparent coating layer 21, and then a second transparent coating layer 22 is applied over said protective coating layer 23, whereby a mirror image of the so-called hidden picture 4 is printed on the second screen printing technique, that the embossed mirror or. inverted image of the hidden or. latent images 4 facing said first transparent coating layer 21. Then, a second layer of adhesive is applied over the second transparent coating layer 22. An adhesive is selected as a thermoactive adhesive that meets the same requirements as in the previously described embodiment of the document of the invention. In this way, after the implementation of the above-mentioned steps, a multilayer 2 coating is applied to the carrier film 3, which is ready for laminating. The subsequent laminating step is then carried out in such a way that the foil 3 with the multilayer coating 2 applied to it is placed over the one available to protect the intended page 1 of the document, and then all together, ie. the carrier film 3 with cover 2 and the said data page 1 are exposed to elevated temperature and sufficient pressure, by activating the adhesive layer 20, the coating 2 is glued to said data page 1, followed by relief in terms of pressure relief and then cooling. The final step of the process in this case also involves the removal of the carrier film 3 with the associated siliconized layer 31 from said multilayer laminated lining 2, which thus remains unbearably mounted on the page 1 of the document available at each time.
Med izvajanjem obeh različic postopka se v fazi laminiranja pod vplivom temperature in pritiska zaradi reliefnosti drugega sloja 22 transparentnega premaza v območju skrite slike 4 prvi sloj 21 transparentnega premaza deformira, s čimer je dobljen optični učinek skrite slike 4. Ta skrita slika, ki je bila na drugem sloju 22 transparentnega premaza nanešena v zrcalni oz. invertirani podobi, je na obravnavani strani 1 dokumenta na voljo v nasprotni t.j. v svoji pravi podobi. Vidna je pri naravni ali umetni navadni oz. dnevni svetlobi, vendar le v primeru, če je osvetljena pod ustreznim kotom glede na površino 11 za zaščito predvidene strani 1, sicer pa je nevidna.During the implementation of both variants of the process, during the lamination phase under the influence of temperature and pressure due to the relief of the second transparent coating layer 22 in the area of hidden image 4, the first transparent coating layer 21 deforms, thereby obtaining the optical effect of hidden image 4. This hidden image, which was on the second layer 22 of the transparent coating applied in the mirror or. in the inverted image, on the page 1 of the document under consideration is available to the contrary i.e. in its true image. It is visible in natural or artificial ordinary or. daylight, but only if it is illuminated at an appropriate angle to the surface 11 to protect the intended side 1, otherwise it is invisible.
Pri tem je tudi pomembno, da je večslojna obloga 2 neodstranljivo nameščena na za zaščito predvideni strani 1 dokumenta, kar pomeni, da odstranitev večslojne obloge 2 ali tudi že zgolj poskus odstranitve na dokumentu povzroči tolikšne poškodbe, da jih je mogoče identificirati že na prvi pogled. Strokovnjakom s tega področja bo razumljivo, da je na ta način možno realizirati proti ponarejanju in prenarejanju ustrezno zaščiten dokument, pri katerem je kot eden od zaščitnih elementov uporabljena skrita slika 4, ki je torej pod določenim kotom vidna tudi pri navadni, bodisi naravni ali umetni, dnevni svetlobi in jo je mogoče z zahtevano natančnostjo izdelati na razmeroma preprost način ter pri tem zagotoviti, da je med uporabo dokumenta zaščitena proti poškodbam. Hkrati je zahvaljujoč načinu izvedbe omenjene skrite slike 4 proti poškodbam in prenarejanju varovana tudi pred tem pripravljena, z vsakokrat potrebnimi podatki in drugimi zaščitnimi elementi opremljena vsakokratna za zaščito predvidene stran 1 dokumenta.It is also important that the multilayer lining 2 is unbearably attached to the intended page 1 of the document, which means that removing the multilayer lining 2 or merely attempting to remove it on the document causes such damage that it can be identified at a glance . It will be appreciated by those skilled in the art that in this way it is possible to realize an appropriately protected document against counterfeiting and falsification, using a hidden figure 4 as one of the security features, which is therefore also visible at a certain angle in ordinary, natural or artificial art. , daylight and can be manufactured with the required precision in a relatively simple manner, ensuring that it is protected against damage when using the document. At the same time, thanks to the method of performing said hidden image 4 against damage and tampering, the security is also prepared beforehand, with the necessary data and other security features being provided at each time to protect the intended page 1 of the document.
Tretja različica dokumenta po izumu je prednostna v primerih, kadar je zaželeno, da je skrita slika 4 ob ustrezni osvetlitvi še posebej dobro vidna, še zlasti pa, daje zaznavna tudi na otip. V tem primeru na proti dokumentu obrnjeni površini 30 nosilne folije 3 nanešeni silikoniziran oz. silikonski sloj 31 sestoji iz dveh plasti 311, 312, in sicer iz motne oz. brezsijajne oz. mat silikonske plasti 312 ter iz sijajne silikonske plasti 311, v kateri so na voljo potrebni elementi podobe skrite slike 4. Omenjena sijajna silikonska plast 311 je obrnjena proti prvemu sloju 21 transparentnega premaza, preko katerega sta spet eden nad drugim ali eden po drugim nanešena drugi sloj 22 transparentnega premaza in sloj 23 zaščitne barve, preko slednjih pa sloj 20 lepila za pritrditev tako sestavljene obloge 2 na vsakokrat ustrezno stran 1 dokumenta. Omenjeni silikonski plasti 311, 312 se odlikujeta po zadostni medsebojni adhezivnosti, ki je večja od njune adhezivnosti proti drugim površinam sosednjih elementov 3, 21. Po laminiranju sta silikonski plasti 311, 312 odstranljivi s strani 1 dokumenta skupaj s folijo 3, vendar na površini sloja 21 transparentnega premaza v območju skrite slike 4 in v preostalih območjih izven slike 4 pustita različna odtisa. Ker se na foliji 3 skrita slika 4 nahaja v območju sijajne silikonske plasti 311, je tudi odtis na površini sloja 21 v območju skrite slike 4 sijajen. Nasprotno pa je površina sloja 21 transparentnega premaza po odstranitvi folije 3 skupaj s silikonskima plastema 311, 312 zaradi predhodnega kontakta zgolj z motno silikonsko plastjo 312 temu ustrezno motna oz. brezsijajna, mat. Kot posledica kontrastnosti površin v območju skrite slike 4 in izven območja le-te je tako dobljena skrita slika 4 sicer šele ob primerni osvetlitvi temu ustrezno bolj kontrastna in zato še bolje vidna. Po drugi strani je v tem primeru skrita slika 4 na voljo na zunanji površini sloja 21 transparentnega premaza, zato je zaznavna tudi na otip, kar pri dokumentu predstavlja možnost uvedbe še enega zaščitnega elementa.The third version of the document according to the invention is preferred in cases where it is desirable that the hidden figure 4, when properly illuminated, is particularly well visible and, in particular, that it is also palpable. In this case, the surface facing up to the document 30 of the carrier film 3 is applied siliconized or. silicone layer 31 consists of two layers 311, 312, namely opaque or. lightless or mat silicone layer 312 and glossy silicone layer 311, which contains the necessary elements of the image hidden picture 4. Said glossy silicone layer 311 faces the first transparent coating layer 21, through which they are applied one above the other or one after the other a transparent coating layer 22 and a protective paint layer 23, and through the latter a glue layer 20 for attaching the coating 2 thus formed to the respective page 1 of the document. Said silicone layers 311, 312 are characterized by sufficient adhesiveness greater than their adhesiveness to other surfaces of adjacent elements 3, 21. After lamination, silicone layers 311, 312 are removable from page 1 together with the film 3, but at the surface of the layer 21 transparent coatings leave different prints in the area of hidden picture 4 and in the remaining areas outside of picture 4. Because the hidden image 4 on the foil 3 is in the area of the glossy silicone layer 311, the imprint on the surface of the layer 21 in the area of the hidden image 4 is also glossy. In contrast, the surface of the transparent coating layer 21 after removal of the foil 3 together with the silicone layers 311, 312, due to prior contact with only a cloudy silicone layer 312, is correspondingly opaque. lightless, matt. As a result of the contrast of the surfaces in the area of the hidden image 4 and beyond the area, the hidden image 4 thus obtained is only more appropriately contrasting and therefore even better visible under suitable illumination. On the other hand, in this case, the hidden image 4 is available on the outer surface of the transparent coating layer 21, so it is also palpable, which in the document represents the possibility of introducing another security element.
