Definitions

  • the present invention relates to a high resolution perforation with color shades and a method for protection, verification and authentication of originality of products.
  • Document WO9718092A1 reveals a method for perforating an image by means of holes with such a size, that the image is visible in transiting light and invisible under reflected light
  • US2006006236A1 describes a method, where the perforated holes have an elliptic shape , which are cross oriented in different directions in order to obtain different images depending on a viewing angle, but non of them describes a method for achieving a perforated image with high resolution and color levels(shades).
  • Document EP0936975B1 discloses a method for obtaining the color levels by means of round holes with different diameters depending on the grey level.
  • a major disadvantage of this method is that it is not possible to achieve a high resolution image - a high number of perforated holes with small distance in between - perforated over a very small area, because in such a case due to the small distance between the holes and the different hole diameters there will be an overlapping of holes, which will significantly deteriorate a quality of the perforated image.
  • the perforation must be carried out with the distance of 200 ⁇ between the hole centers which will result in the overlapping of the holes, and will lead to lower quality of the perforated image as well as to destruction of the structure of the protected object.
  • the last can cause its rupture or breaking and destruction either during the perforation or later when the protected object is utilized.
  • the perforation proposed in the present invention and the method do not have such problems and disadvantages since the perforation is carried out with the same fixed size of the holes and same distance between them and at the same time the perforated image features the high density of perforated holes and resolution.
  • the security perforation represents the perforation of a certain image, like a photograph of an owner of an identity document, a logo, a number or other image.
  • the said images have their digital format obtained by scanning, digital photographs or other means for digitalisation.
  • the digital image represents a set of digital values, called picture elements or pixels, which describe the color shades of the image and can be different in quantity (number) depending on a image classification. For instance 256 shades of gray in so-called gray-scale digital images or 65536 colors - respectively color levels, and in some cases only two - black and white for so-called monochromatic (binary) images.
  • any of the respective color levels are represented by the holes with a different shape and the same size (diameter, sides, etc.) where for a certain color level is juxtaposed a perforated hole with an exact predetermined shape and for the other level - another shape of the hole.
  • the shape of the holes is defined in such a way, to be with rising or decreasing filling depending on the shades of the colors.
  • the so-acquired high resolution and high quality perforated images serve as an unique security feature for protection against counterfeiting and forgery of a large spectrum of documents, such as passports, ID (identity) cards, driving licenses, access authorization documents (permits), Visa stickers, etc., as well as of any securities - banknote, cheques, excise labels, package lists, etc.
  • the applied perforation itself can be a serial number of a protected object, a face image of a holder of the identity document or any other image - a logo, a coat of arms, etc. Counterfeiting will be very difficult because of the high quality and resolution of the perforated image, which facilitates its clear recognition and authentication.
  • identity documents are protected by means of perforation of the face image of the document owner, can his identity and the authenticity of the document be verified unambiguously, due to the high resolution and quality of the perforation even in cases of attempts to forge the owner's photograph printed over the document.
  • the high density of the perforated image permitting its application over smaller areas of the document creates additional difficulties to counterfeiting.
  • the perforation can be carried out be means of mechanical, laser, ion or any other kind of perforation - cutting holes.
  • Laser and micro perforation are particularly appropriate in order to achieve very high resolution and quality of the perforated image over different groups of materials depending on the wavelength of the lasers. 10600 nm wavelength is used for different types of paper and plastic material, while for metals is used the 1064nm wavelength, etc.
  • Fig.1. - shows a perforation of an image by means of holes with the constant size and shape and the constant distance between the holes.
  • Fig.2. - shows a perforation of an image by means of holes with the same size and same distance between them, where the holes have different rounded shape depending on the shade of gray.
  • Fig.3. - shows a perforation of an image by means of holes with the same size and same distance between them, where the holes have different non-rounded shape depending on the shade of gray.
  • Fig.4. - shows a perforation of an image by means of holes with the same size and shape and the same distance between the holes, where the image is converted to black and white.
  • Fig.l shows an example of the invention, where the input is a black and white (monochromatic) image (1) and the said image is transformed to the resolution for perforating by resizing the image.
  • the ready image is perforated by means of holes with the same size, which are spaced over the predefined fixed distance between them.
  • the shade of white (2) or the shade of black (3) depending on the preferred visual perception effect will be perforated only the shade of white (2) or the shade of black (3).
  • white shade perforation we obtain a negative image, that is better perceived in the transitting rather than in reflected light
  • a positive perforated image which is better perceived in reflected light.
  • a color image that is at first transformed to black and white and then perforated as described above.
  • Another preferred embodiment is in the case of an image of gray-scale type with 256 color shades of the gray color is shown in fig.2, where depending in the color level (1) holes are perforated with a relevant shape (2) and for a group of color levels(shades) the holes are perforated with the same shape (2) in order to have the perforated image (3) for the protection of a passport (4).
  • a black and white image - in this particular example is used the Floyd-Steinberg method, which is perforated for protection against counterfeiting by means of the holes with the same size, spaced over the same predefined distance and again depending on the preferences for the visual effect either only white shade (2) or only black shade (3).
  • Another methods can be used for obtaining of a halftone image, like Jarvis, Stucki, Cardinality-Distribution, simple thresholding, et c, which are well known and are not an object of the present invention, and to obtain a black and white image the holes are perforated with the same size and the same distance in a perforation matrix(grid) for obtaining a high resolution security perforation, like (2) and (3) for protecting a passport (4) or an identity card (5).
  • a perforation matrix(grid) for obtaining a high resolution security perforation, like (2) and (3) for protecting a passport (4) or an identity card (5).
