Description

PRE—PRINTING OR OVERPRINTING METHOD FOR RENDERING
UNIQUE, VIA AIRBRUSHING OR LASER ENGRAVING, ANY PRINTED SIGN, LOGO, OR ALPHANUMERIC CODE AND RENDERING IT DISTINGUISHABLE FROM A COPY THEREOF
DESCRIPTION
Technical sector of the invention
The invention relates to an innovative, simple method that is applied on printing machines or accessories and makes it possible to obtain, via airbrushing, a unique sign that, once detected and filed so that it is available for future comparison, serves to distinguish the original from a copy. In various preferred applications, the invention regards, in particular, the way of applying distinguishing marks on each individual print or two-dimensional alphanumeric code, via erosion of the colour or overprinting obtained with an airbrush jet. In the case of the two-dimensional alphanumeric code, the method also makes it possible to distinguish between an original and its photocopy.
Prior art
In the sector of graphic printing in general, there is known the idea of micro-encapsulating the colours to be printed for creating unique and differentiated patterns that are then filed for future comparison of authenticity. These solutions are described in the international patent application documents Nos. W02008059552 and W02010001203 filed in the name of the present inventor. In this printing system, which is principally suited to offset printing, the micro-capsules of different colours are mixed with a paint or using a purposely provided accessory, randomly sprinkled over a base medium, and then pressed and squeezed, thus generating unique printed signs, which are then detected, using a camera, and filed.
The patent No. EP 1953684 discloses a pre-printing or overprinting method for rendering unique a printed logo or an alphanumeric code, using a nonlinear sign created by an ink-jet airbrush, where the airbrush is mounted on an arm so as to generate, on each print, a random and differentiated sign.
The method that is described herein differs from the teachings of the known art as regards simplicity of application and innovation since it excludes some constraints and steps that were previously necessary and enables a greater flexibility of application on any type of printing machine.
Purpose of the invention
The purpose of the present invention is to propose a new method for rendering unique any print, logo, or datum that differs from the methods described in the aforementioned documents of the prior art since it intervenes on a sign already printed via pre-printing or overprinting obtained with a jet of colours or erosive liquids by means of an airbrush or using a laser beam. The airbrush or the device for printing or engraving using a laser beam acts via a mechanics with random oscillating movement, continuously creating differentiated and unique etches or engravings directly on the stabilized sign of the print or using a silicone-based or erosive jet prior to printing.
Furthermore, according to a peculiar characteristic of the invention, to distinguish an original sign from a photocopied one, a further overprint is envisaged on the nonlinear mark obtained using the airbrush or device for laser printing or engraving, with security colours that are iridescent at the wavelengths of the visible and are hence such as to change when viewed from different angles.
Summary of the invention
The above purposes are achieved with a method and an apparatus according to at least one of the annexed claims .
A first advantage lies in the fact that, with the invention, it is possible to apply, via a simple accessory arm, one or more airbrushes directly on any offset-printing or flexographic line, and intervene on the process in order to produce a number of unique signs, without reducing the machine speed.
A second advantage lies in the fact that the iridescent security colour is overprinted using a normal printing process in a machine with a photoengraved cliche or plate.
A third advantage lies in the fact that, with this new system, for example, a two-dimensional barcode can be rendered unique and immediately distinguishable from a photocopied one.
Finally, a fourth advantage lies in the fact that it is possible to position the airbrush of the laser with millimetric precision on the portion of the print on which it is intended to intervene to render it unique.
List of the drawings The above and further advantages will be better understood by any person skilled in the branch from the ensuing description and the annexed drawings, which are provided purely by way of non-limiting example and in which:
Figure 1 is a schematic illustration of the various steps for rendering an alphanumeric code unique and distinguishable from a possible copy, via overprinting;
Figure 2 is a schematic illustration of the various steps for rendering an alphanumeric code unique and distinguishable from a possible copy, via pre¬ printing; and
Figure 3 shows the difference between some prints of alphanumeric codes that are the same but are rendered unique by applying the method illustrated hereinafter .
Detailed description
The method forming the subject of the present invention has the purpose of rendering any sign, logo, or datum different and personalized.
Presented herein as illustrative example is direct intervention on the printing line or off-line through an accessory line in order to render an alphanumeric code of any kind unique. In Figure 1, directly on the printing line on the machine, an ink-jet printer 1 prints an alphanumeric code la. Then, proceeding towards the right, said alphanumeric code passes under an industrial airbrush 2, which, with a nozzle, sprays a jet of white colour on the print, thus creating a nonlinear asymmetrical and undulated mark, which in part covers said alphanumeric code, giving rise to a different alphanumeric code, here designated by the reference 2a. The nonlinearity of the mark is due to the random and differentiated movement of the spray of the industrial airbrush, which is mounted on an oscillating mechanical arm (not visible in the figure) . The differentiated randomness of the spray that intersects the static print of the alphanumeric code creates a print that is unique and different from the serial prints similar to it.
Currently, one of the problems of counterfeiting an original sign is represented by a copy obtained using a high-definition photocopier.
According to the present invention, to overcome this problem, it is envisaged, via a photoengraved cliche or plate 3, to print, on the white spray created by the industrial airbrush, a series of dots designated by 3a, with colours that are iridescent at the wavelengths of the visible and are hence such as to change when viewed from different angles.
Hence, in the original it will be possible to appreciate the iridescent variant of a combination of two colours, whereas on the copy there will be just a single colour different from the original.
After printing, the alphanumeric code passes under a UV lamp 4, which dries and stabilizes the colour to give rise to the final alphanumeric code designated by 4a. Finally, the alphanumeric code, thus rendered unique, together with its uniqueness, is detected by a high-definition camera 5, which, using a software, processes a datum 5a, which is then sent to an archive for future comparison of originality.
Represented schematically in Figure 2 is the same method with the difference that, by means of the industrial airbrush 6, using a nozzle, an asymmetrical and oscillating jet of silicone-based liquid is sprayed, limited to the space 6a where the alphanumeric code will be printed. As has already been said, the nonlinearity of the spray is due to the oscillation of the industrial airbrush, which is mounted on a mechanical arm. Then, the code passes under an ink-jet printer 7, which prints an alphanumeric code designated by 7a. Since the ink of the printer does not adhere where the liquid containing silicone has been sprayed, a print is created that is unique and different from the serial prints similar to it.
To distinguish the original from a possible photocopy on the code 7a, via a photo-engraved cliche or plate 8, a series of dots 8a will be printed with colours that are iridescent at the wavelengths of the visible and are hence such as to change when viewed from different angles.
As the print advances in the process, a UV lamp 9 dries and stabilizes the ink of the alphanumeric code 8a. The final result is designated by 9a. Lastly, this alphanumeric code is then detected via a high- definition camera 10, which, via a software, processes a datum 10a, which is then sent to an archive.
Highlighted in Figure 3 is how intervention of the nonlinear spray of the airbrush renders each individual alphanumeric code different from the others and unique (11-12-13) . The present invention has been described and illustrated by way of example according to preferred embodiments, but equivalent variants may be devised without thereby departing from the sphere of protection granted.
