Definitions
- the present invention relates to a method of printing a security element for securities, such as bank notes, checks, credit cards, passports or identity documents and other similar documents.
- the present invention also relates to a security element for securities, such as for example bank notes, passports, identity documents and the like.
- Such security elements use, for example, specific inks such as optically variable inks ("ONI” ®) and other inks having iridescent properties, these inks being used to print particular patterns or geometric shapes on the substrate of the paper-value, optically variable elements (“OND” ®) in the form of metallic patches (called “foils”) or holograms, and also moire and other similar patterns, all being, on the one hand, very difficult or even impossible to copy with current devices but, on the other hand, very easy to control visually or with the naked eye.
- Other security elements are formed by combinations of overlapping lines and / or patterns with colors, which are only visible under certain conditions, for example UN light or in transparency. Again, the advantage of such security elements is that they are easy to print or place on the document to be protected and they can be controlled by simple devices, even with the naked eye, but they are impossible to reproduce with current printers, scanners and photocopiers.
- US Pat. No. 6,050,606 incorporated by reference in the present application, describes a security element for securities, for example for banknotes.
- This security element is formed by a background having at least two juxtaposed regions, each region having its own geometric designs, said regions having a different color density.
- the security element further comprises a pattern corresponding to the region with the lowest color density which is printed superimposed on said region in a chosen color so as to compensate for the difference in color density between said two regions.
- the security element appears uniform and without pattern to the naked eye, but the pattern appears clearly during a photocopy of said element.
- Another specific technique uses watermarks in which the substrate, for example paper, is marked with lines or a pattern which are visible only in transparency.
- a development of this technique relates to pseudo-watermarks formed by the creation of a window in the substrate, a technique used in particular with paper substrates which are themselves not normally transparent, said window being itself transparent.
- the layer having specific optical properties has a dark color, for example black.
- black layer prevents the detection of the difference in contrast so that the information formed by the demetallization disappears completely on a copy of this element of security.
- a laser is used either to mark the substrate directly or to mark a layer applied to said substrate and thus create security elements impossible to reproduce by photocopying or scanning.
- An object of the invention is to define an improved printing method for a security element used in particular on securities. Another object of the invention is to create a security element for securities improving the elements already known and requiring a simple and easy to implement method.
- Another object of the invention is to provide a security element which is very difficult to copy and counterfeit with modern standard scanners and photocopiers and other equivalent devices but which can be easily printed with current printing means.
- Figure 1 shows a block diagram of the printing process forming a security element according to the invention.
- FIG. 2 shows a first embodiment of a security element according to the invention.
- FIG. 3 shows a second embodiment of a security element according to the invention.
- FIG. 4 shows a security paper comprising a security element according to the invention.
- a background is first printed on the substrate, for example using an offset method known in the state of the art.
- the background can be monochrome or polychrome, such printing can be carried out by the methods known from the state of the art.
- the pattern which will be printed is transferred from an offset plate cylinder inked by ink rollers to a blanket cylinder which in turn transfers the pattern to the substrate, for example paper.
- Patent application FR 2 222 214 describes an offset printing process and an offset printing machine. The content of this request, in particular the part relating to offset printing, is incorporated by reference into the present request.
- US Pat. No. 6,101,939 the content of which is incorporated by reference to the present application, describes another printing machine using the offset process.
- This background can extend to the entire surface of the security paper or be limited to a particular area thereof.
- a semi-transparent pattern is then printed using an appropriate printing process using an optically variable ink.
- inks which have iridescent properties, contain metal particles and are generally applied in the form of an opaque pattern on the security papers, said pattern forming a security element.
- these patterns formed from optically variable ink change color depending on the angle from which they are viewed, the colors depending both on the color of the ink itself. - even and metal particles.
- Such inks are particularly effective in forming security elements because it is not possible to reproduce the iridescence effect with color photocopiers or scanners: during copying, the pattern formed from optically variable ink loses in particular its iridescence properties so that a copy is easy to identify with the naked eye.
- the semi-transparent pattern in optically variable ink is printed by a screen printing process.
- a screen printing process is known in itself in the state of the art.
- the pattern to be printed is formed by a sieve through which the ink is applied to the substrate, for example value paper.
- the holes in the screen are closed outside the pattern, so that the ink passes through the screen to form the pattern itself on the substrate, while for negative printing, the holes corresponding to the pattern are closed and the ink marks the outline of the pattern, the pattern itself being created by the absence of ink on the substrate.
- US Patents 6,109,172 and US 5,671,671 the contents of which describe screen printing machines, are incorporated by reference into the present application.
- a determined printing process is combined, for example a screen printing process as described above and in the mentioned US patents, with optically variable ink but the fineness of the screen for screen printing, that is to say the size of the holes in the sieve, is chosen so that the pattern created in screen printing with optically variable ink is semi-transparent.
- the background printed on the substrate is seen through the semi-transparent pattern in optically variable ink, nevertheless, on the other hand, said pattern being formed in optically variable ink, it retains iridescent properties. due to optically variable ink.
- the fineness of the screen is of the order of 180 to 230 lines per inch, in each direction X and Y of the screen.
- a fineness of the order of 230 lines per inch is chosen.
- the fineness of the screen can be adapted as a function of the optically variable ink used and in particular of the size of the metal particles contained in said ink, the aim being to obtain a semi-transparent impression with the optically variable ink.
- the optimization of these parameters can of course be done by simple printing tests to adjust the size of the holes - and consequently the amount of ink deposited during - printing to obtain the desired effect.
- a printing form is preferably used with a screen fineness of the order of 60 to 120 lines per centimeter, the screen angle of which can vary from 0 ° to 75 ° and whose the depth of the etched cells is between 10 microns and 50 microns.
- These parameters can of course be adapted according to the type of optically variable ink used and the degree of transparency that it is desired to obtain. The adjustment of these parameters can in particular be done by comparative tests.
- an anylox cylinder is used having a linearity of the order of 100 to 120 lines per centimeter, the cell depth of which is between 30 microns and 50 microns.
- the parameters can be adapted according to the type of optically variable ink used and the degree of transparency that it is desired to obtain.
- a step of dry embossing of the security element is then carried out.
- This step makes it possible to form an additional, raised pattern in the security element created by the superposition of the background and the semi-transparent printing, a raised pattern which it is of course also impossible to reproduce by photocopying or scanning. .
- a conventional intaglio process can be used in the printing field, omitting the use of ink to obtain a dry embossing.
- This pattern is also only visible according to a particular viewing angle of the security element, which, in such an embodiment, combines color effects, iridescence and a tactile effect by the relief pattern.
- FIG. 2 shows a security element according to the invention with a bottom 1, printed for example in offset, and which includes the alphanumeric characters "2000" placed one next to the other.
- a pattern 2 was printed in semi-transparency with an optically variable ink.
- optically variable ink is used for pattern 2, which pattern is normally opaque due to optically variable ink
- the printing process for pattern 2 is such that said pattern is semi-transparent, so that the bottom 1 is visible through the pattern 2.
- a process that can be used to create the semi-transparent pattern with optically variable ink is a screen printing process in which the screen has a fineness particular, namely from 180 to 230 lines per inch.
- a pattern is thus obtained having both the properties of a pattern printed with optically variable ink and also having a semi-transparent effect allowing the background on which it is printed to be seen.
- FIG. 3 the various elements making up the security element according to the invention have been brought out in a particular embodiment.
- the background 1 comprising the characters "2000" repeated regularly, then we distinguish the pattern 2 semi-transparent in optically variable ink through which we can see the characters of the background thanks to the effect of semi -transparency.
- a relief pattern 3 in this case a face, which has been formed, for example, by dry embossing of the security element.
- a degree of security is thus added to the element, in that not only is it semi-transparent, it has the characteristics of a security element in optically variable ink, but in addition a relief is added by dry embossing, all these different properties being very difficult, if not impossible, to reproduce with a modern photocopier or scanner.
- a security paper 4 is shown by way of example with a security element according to the invention.
- This value paper 4 in this case, a schematic bank note, has in its lower corner a security element with a bottom 1, a semi-transparent pattern 2 in optically variable ink and a dry embossing 3 as shown with reference to FIG. 3 of the present application. It should be noted that the bottom 1 may extend over the entire surface of the security paper.
