Dal Titolo: By title:
SISTEMA DI MICROINCISIONE MEDIANTE MATRICI REALIZZATE IN MATERIALE PLASTICO DI ELEVATA DUREZZA, E IN PARTICOLARE, INCISIONE OLOGRAFICA SU TONER TERMOPASTICI DEL TIPO UTILIZZATO NELLE STAMPANTI LASER E/O CON OGNI ALTRO TIPO DI INCHIOSTRO TERMOPLASTICO O SUPPORTO PLASTICO MICRO-ENGRAVING SYSTEM USING MATRICES MADE OF HIGH HARDNESS PLASTIC MATERIAL, AND IN PARTICULAR, HOLOGRAPHIC ENGRAVING ON THERMOPASTIC TONERS OF THE TYPE USED IN LASER PRINTERS AND / OR WITH ANY OTHER TYPE OF THERMOPLASTIC INK OR PLASTIC SUPPORT
La presente invenzione concerne un sistema di microincisioni su toner termoplastico o su altri materiali termoplastici, mediante matrici realizzate su film plastici di durezza superiore e temperatura di rammollimento superiore a quella del toner termoplastico, su cui si vanno ad incidere i microsolchi olografici. The present invention relates to a system of micro-incisions on thermoplastic toner or on other thermoplastic materials, by means of matrices made on plastic films of higher hardness and softening temperature higher than that of thermoplastic toner, on which the holographic micro-grooves are engraved.
Le matrici in materiale plastico si ottengono mediante le tecnologie per la produzione di film plastici olografici descritte nei brevetti italiani N. The matrices in plastic material are obtained through the technologies for the production of holographic plastic films described in the Italian patents N.
1.217.385 e 1.275.183 a nome dello stesso autore della presente invenzione. Scopo della presente invenzione à ̈ la realizzazione di un sistema di goffratura adatto alla microincisione di una stampa ottenuta dalle comuni stampanti laser, che hanno la caratteristica di utilizzare un toner termoplastico come inchiostro di stampa. 1,217,385 and 1,275,183 in the name of the same author of the present invention. The purpose of the present invention is the realization of an embossing system suitable for the micro-engraving of a print obtained by common laser printers, which have the characteristic of using a thermoplastic toner as printing ink.
Le necessità di rendere i documenti cartacei per uso legale ad originali con alto grado di protezione contro la contraffazione à ̈ stata già sviluppata mediante i brevetti N.1.2173385 e 1.275.183 dello stesso autore. The need to return paper documents for legal use to originals with a high degree of protection against counterfeiting has already been developed through patents no.1.2173385 and 1.275.183 of the same author.
Tale tecnologia implica che per rendere tali documenti sicuri à ̈ necessario stampare o trasferire l’incisione olografica su supporti termoplastici i quali, in seguito, trasformati in etichette o trasferiti direttamente con trasferimento a caldo, vengono applicati sui documenti. This technology implies that to make these documents secure it is necessary to print or transfer the holographic engraving on thermoplastic supports which, later, transformed into labels or transferred directly by heat transfer, are applied on the documents.
Il processo descritto à ̈ altamente sicuro contro la contraffazione ed à ̈ economicamente appetibile solo se si producono centinaia di migliaia di copie. The process described is highly secure against counterfeiting and is only economically viable if hundreds of thousands of copies are produced.
La presente invenzione permette di trasferire l’informazione olografica personalizzata sul toner della stampa ed a sua volta su una singola copia, mediante la matrice olografica di materiale plastico. The present invention allows to transfer the personalized holographic information on the toner of the print and in turn on a single copy, by means of the holographic matrix of plastic material.
Le microincisioni olografiche vengono incise solo nelle zone stampate con il toner termoplastico e registrano le informazioni nei rilievi termoplastici del toner. Tale sistema implica un enorme risparmio economico di lavorazione dell’ologramma personalizzato dovuto ad i seguenti elementi: The holographic micro-engravings are engraved only in the areas printed with the thermoplastic toner and record the information in the thermoplastic pads of the toner. This system implies an enormous economic saving in processing the customized hologram due to the following elements:
1- Personalizzazione olografica di qualsiasi scrittura, logo o immagine, del documento stampato con il toner termoplastico. 1- Holographic customization of any writing, logo or image of the document printed with thermoplastic toner.
2- Utilizzazione delle matrici olografiche realizzate su materiale plastico migliaia di volte più economiche di quelle utilizzate con struttura metallica (NICHEL) per stampare gli ologrammi con tecnologie dei brevetti N.1.217.385 e 1.275.183; 2- Use of holographic matrices made on plastic material thousands of times cheaper than those used with a metallic structure (NICKEL) to print holograms with technologies of patents N.1.217.385 and 1.275.183;
3- Utilizzazione calibrata delle matrici in plastica per molteplici incisioni a differenza della stampa a caldo dell’ologramma come sulla cartamoneta o la carta di credito dove il film olografico trasferito sulla carta può essere usato una singola volta poiché tale tecnica permette il trasferimento del toner termoplastico preinciso olograficamente sul supporto cartaceo. 3- Calibrated use of plastic matrices for multiple engravings unlike hot stamping of the hologram such as on paper money or credit card where the holographic film transferred to the paper can be used a single time since this technique allows the transfer of the thermoplastic toner pre-engraved holographically on the paper support.
4- Possibilità di trasferire microincisioni multiple sullo stesso documento cartaceo. 4- Possibility of transferring multiple micro-engravings on the same paper document.
5- L’incisione olografica sui toner termoplastici depositati sulla carta stampata crea colori iridescenti olografici sul toner colorato della stampa, lasciando inalterati i colori della stampa. 5- The holographic engraving on the thermoplastic toners deposited on the printed paper creates holographic iridescent colors on the colored toner of the print, leaving the colors of the print unaltered.
Il sistema di microincisione di toner termoplastico utilizza una coppia di cilindri di calandratura costituite da due cilindri in acciaio rivestiti di materiale sintetico di durezza elevata, avente una elevata resilienza superficiale. The thermoplastic toner micro-etching system uses a pair of calendering cylinders made up of two steel cylinders coated with a synthetic material of high hardness, having a high surface resilience.
Le superfici dei cilindri hanno un elevato grado di linearità non inferiore all’ordine di grandezza del grado di risoluzione delle microincisioni presenti sulla superficie di materiale plastico. I due cilindri vengono riscaldati mediante resistenze elettriche che possono essere applicati sia all’interno dei cilindri di goffratura, sia riscaldati mediante irraggiamento di due piccoli forni applicati in prossimità dei cilindri di calandratura. The surfaces of the cylinders have a high degree of linearity not less than the order of magnitude of the degree of resolution of the micro-engravings present on the surface of plastic material. The two cylinders are heated by electric resistances which can be applied both inside the embossing cylinders, and heated by the irradiation of two small ovens applied near the calendering cylinders.
Sonde di temperatura sono applicate in prossimità dei due cilindri di goffratura, in modo da controllare e regolare le temperatura dei cilindri mediante un termoregolatore. Temperature probes are applied near the two embossing cylinders, in order to control and regulate the cylinder temperatures by means of a thermoregulator.
Le caratteristiche del trovato risulteranno più evidenti dalla descrizione che segue relativa ad esempi di carattere non limitativo le cui figure rappresentato schematicamente: The characteristics of the invention will be more evident from the following description relating to examples of a non-limiting nature, the figures of which are schematically represented:

In Figura 1 à ̈ indicato molto schematicamente il gruppo di due cilindri di goffratura per l’incisione di toner termoplastici mediante cliché plastico avente microincisioni olografiche. Figure 4: Compendium of machining composed of the machining application. a) holographic plastic clichà ©; b) sheet printed with thermoplastic toner; c) base â € “cardboard support Figure 5: Separation of the plastic plate from the sheet of paper printed with a laser printer and engraved with iridescent holographic micro-grooves. Figure 1 shows very schematically the group of two embossing cylinders for the engraving of thermoplastic toners by means of a plastic cliché having holographic micro-engravings.
I cilindri A e B devono presentare caratteristiche usualmente richieste per i cilindri goffratori rivestiti di materiale sintetico duro rettificato e lappato ed eventualmente bombato per compensare la flessione dovuta alla pressione di spinta, con grado di finitura molto alto, tale che lungo una generica retta generatrice della superficie cilindrica, la superficie del cilindro presenti un grado di linearità (vale a dire di approssimazione della linea retta) non inferiore all’ordine di grandezza del grado di risoluzione delle microincisioni presenti sul cliché di materiale plastico. The cylinders A and B must have characteristics usually required for embossing cylinders coated with hard synthetic material, rectified and lapped and possibly rounded to compensate for the bending due to the thrust pressure, with a very high degree of finish, such that along a generic line generating the cylindrical surface, the surface of the cylinder has a degree of linearity (ie approximation of the straight line) not less than the order of magnitude of the degree of resolution of the micro-engravings present on the plastic plate.
Un valore tollerabile di linearità potrebbe essere ad esempio dell’ordine di 2000 linee al mm. A tolerable linearity value could be, for example, of the order of 2000 lines per mm.
Per la rotazione, i due cilindri sono sorretti alla loro estremità da due supporti e sono tenuti costantemente in pressione, mediante pressione meccanica o pneumatica. For rotation, the two cylinders are supported at their ends by two supports and are kept constantly under pressure, by mechanical or pneumatic pressure.
Nella figura 2 à ̈ rappresentato schematicamente il cliché costituito da un foglio “a†di materiale termoplastico avente microsolchi con microincisioni olografiche realizzate con le tecnologie descritte nei brevetti N.1.217.385 e 1.275.183. Figure 2 schematically represents the clichà © consisting of a sheet â € œaâ € of thermoplastic material with micro-grooves with holographic micro-engravings made with the technologies described in patents N.1.217.385 and 1.275.183.
Nella figura 3 à ̈ rappresentato schematicamente un semplice foglio “b†di carta stampata con toner termoplastico tipico delle classiche stampanti da ufficio. Figure 3 schematically represents a simple sheet â € œbâ € of paper printed with thermoplastic toner typical of classic office printers.
La figura 4 rappresenta schematicamente il compendium di lavorazione composto da: Figure 4 schematically represents the processing compendium consisting of:
a- clichà ̈ di materiale plastico recante le microincisioni olografiche; b- foglio di carta stampata con toner termoplastici; a-clichà ̈ of plastic material bearing holographic micro-engravings; b- sheet of paper printed with thermoplastic toners;
c- un foglio di base in cartoncino leggero con finitura superficiale super lappata. c- a base sheet of lightweight cardboard with a super lapped surface finish.
Il foglio di carta stampata con il toner termoplastico viene posizionato tra il cliché di materiale plastico e il cartoncino di supporto. Le microincisioni olografiche del cliché plastico sono appoggiate sul foglio di carta stampata con toner termoplastico e sono tenute insieme mediante collegamento (non indicato in figure) del cliché termoplastico a un lato del cartoncino di supporto del compendium. The sheet of paper printed with the thermoplastic toner is positioned between the plastic plate and the support cardboard. The holographic micro-engravings of the plastic plate are placed on the sheet of paper printed with thermoplastic toner and are held together by connecting (not shown in the figures) the thermoplastic plate to one side of the supporting cardboard of the compendium.
Durante il funzionamento i tre elementi (cliché plastico, foglio di carta stampato con toner termoplastico e cartoncino di supporto) vengono posti uno sull’altro congiuntamente e vengono inseriti manualmente o automaticamente tra i due cilindri di goffratura. I due cilindri sono riscaldati mediante resistenza elettrica all’interno dei cilindri o mediante piccoli forni di irraggiamento situati in prossimità dei due cilindri, in modo da assicurare sul compendium abc (Fig 1) in transito una temperatura idonea in funzione della pressione e della velocità . Tale temperatura nei cilindri risulterà funzione della pressione e delle velocità operativa in quanto, a velocità inferiori dovranno corrispondere, a pari temperature sul toner termoplastico, temperature dei cilindri maggiori. During operation, the three elements (plastic clichà ©, sheet of paper printed with thermoplastic toner and backing cardboard) are placed one on top of the other jointly and are inserted manually or automatically between the two embossing cylinders. The two cylinders are heated by means of an electric resistance inside the cylinders or by means of small irradiation ovens located near the two cylinders, in order to ensure a suitable temperature on the compendium abc (Fig 1) in transit according to pressure and speed. . This temperature in the cylinders will be a function of the pressure and the operating speed since, at lower speeds, higher cylinder temperatures must correspond to the same temperatures on the thermoplastic toner.
Da quanto descritto appare chiaro come sia possibile e come avvenga il trasferimento sul toner termoplastico in transito delle microincisioni presenti sul cliché olografico plastico. From what has been described it is clear how it is possible and how it is possible to transfer the micro-incisions present on the plastic holographic cliché onto the thermoplastic toner in transit.
Durante il passaggio del compendium il toner termoplastico presente sul foglio b prestampato deve raggiungere nelle zone di contatto l’opportuna temperatura e pressione sullo strato superficiale. Di conseguenza il cliché plastico à ̈ in grado di imprimere le microincisioni sullo strato del toner termoplastico, microincisioni che dopo l’uscita del compendium dai rulli goffratori, resteranno permanentemente impresse. During the passage of the compendium, the thermoplastic toner present on the pre-printed sheet b must reach the appropriate temperature and pressure on the surface layer in the contact areas. Consequently, the plastic clichà © is able to imprint the micro-incisions on the layer of the thermoplastic toner, micro-incisions which, after the compendium comes out of the embossing rollers, will remain permanently impressed.
Fondamentale à ̈ il rapporto tra la pressione e la temperatura dei due cilindri, al fine di permettere alle microincisioni sulla matrice plastica di penetrare nel toner termoplastico per lasciare permanentemente l’impronta delle microincisioni stesse. The relationship between the pressure and the temperature of the two cylinders is fundamental, in order to allow the micro-engravings on the plastic matrix to penetrate into the thermoplastic toner to permanently leave the imprint of the micro-engravings themselves.
Grazie ad un sistema motorizzato e di compressione meccanica o pneumatica i cilindri sono in continua rotazione e spinti l’un l’altro permettono il trascinamento della piccola pila del compendium abc dal lato dell’inserimento al lato di fuoriuscita dove ci sarà un vassoio apposito D di raccolta (fig 1). L’operatore può prelevare il compendium direttamente dal vassoio D di fuoriuscita. Una volta prelevato dovrà sollevare il lembo del cliché plastico olografico (fig 5, a) per separare il cliché di plastica dal foglio di carta stampato con toner termoplastico (fig 5, b). Il foglio di carta stampato con toner termoplastico presenterà le iridescenze olografiche mentre i colori del documento stampato resteranno inalterate. La sequenza delle operazioni appena descritta può essere immediatamente rieseguita su un nuovo foglio di carta stampato con toner termoplastici, il quale può essere composto da altre scritture, altri loghi e altre immagini, mentre il cliché olografico di materiale plastico può essere lo stesso o di altro disegno artistico. Sia riutilizzando lo stesso clichà ̈ che cambiando il disegno con un nuovo cliché le informazioni/iridescenze olografiche andranno nuovamente ad imprimere il toner termoplastico, dopo aver eseguito le operazioni in precedenza, lasciando ancora una volta inalterati i colori originali della stampa. Thanks to a motorized and mechanical or pneumatic compression system, the cylinders are in continuous rotation and pushed together, they allow the small pile of the compendium abc to be dragged from the insertion side to the exit side where there will be a special collection tray D (fig 1). The operator can take the compendium directly from the output tray D. Once picked up, you will have to lift the edge of the holographic plastic plate (fig 5, a) to separate the plastic plate from the sheet of paper printed with thermoplastic toner (fig 5, b). The sheet of paper printed with thermoplastic toner will show holographic iridescences while the colors of the printed document will remain unchanged. The sequence of operations just described can be immediately re-executed on a new sheet of paper printed with thermoplastic toners, which can be composed of other writings, other logos and other images, while the holographic plate of plastic material can be the same or other artistic design. Either by reusing the same clichà ̈ or by changing the design with a new clichà ©, the information / holographic iridescences will again imprint the thermoplastic toner, after having performed the operations previously, leaving once again the original colors of the print unaltered.
Strategicamente si può stabilire una vita di utilizzo del cliché plastico secondo le esigenze di utilizzo. La vita del cliché dipenderà dalle caratteristiche fisico-chimiche del supporto su cui à ̈ stato inciso. It is possible to strategically establish a life of use of the plastic clichà © according to the needs of use. The life of the clichà © will depend on the physico-chemical characteristics of the support on which it was engraved.
Nel sistema secondo l’invenzione sopra descritto come esempio di riferimento; la microincisione di toner termoplastico à ̈ eseguita su fogli di carta, per esempio del tipo A4. In the system according to the invention described above as a reference example; the micro-engraving of thermoplastic toner is performed on sheets of paper, for example of the A4 type.
Risulta tuttavia che lo stesso sistema può essere adottato per microincisioni su toner, vernici, inchiostri plastici, fogli di plastica aventi caratteristiche di temperatura di rammollimento inferiore a quella del cliché di plastica utilizzato per l’incisione. However, it appears that the same system can be used for micro-incisions on toner, paints, plastic inks, plastic sheets with softening temperature characteristics lower than that of the plastic clichà © used for engraving.
Tutte le microincisioni olografiche trasferite sul toner termoplastici possono essere relative ad ologrammi o reticoli di diffrazione, a Criptogrammi, a nano strutture comprese le antenne R-FID. All the holographic micro-engravings transferred on the thermoplastic toner can be related to holograms or diffraction gratings, to Cryptograms, to nano structures including R-FID antennas.
Secondo il predetto sistema i fogli di carta stampati con toner termoplastici ed incisi con le iridescenze olografiche sono ottenuti mediante processo di calandrature aggiustando i valori della temperatura, della pressione e della velocità di lavorazione dei cilindri di calandratura. According to the aforementioned system, the sheets of paper printed with thermoplastic toner and engraved with holographic iridescences are obtained by means of a calendering process by adjusting the values of the temperature, pressure and processing speed of the calendering cylinders.
