Description

PROCESO PARA LA GENERACIÓN DE IMÁGENES VARIABLES DIMTRO DE PELÍCULAS METALIZADAS Y PELÍCULAS HOLOGRÁFICAS METALIZADAS  PROCESS FOR THE GENERATION OF VARIABLE IMAGES DIMTRO OF METALIZED FILMS AND METALLIZED HOLOGRAPHIC FILMS
Campo de la invención La invención se relaciona con la generación de imágenes variables dentro de películas metalizadas y holográficas utilizadas en documentos oficiales, tarjetas plásticas valores, billetes de lotería, certificados, timbres fiscales, diplomas, boletería de espectáculos, todo tipo de identificaciones, seguros, y en general todo tipo de formas valoradas para evitar fraudes, adulteraciones y falsificaciones . Field of the invention The invention relates to the generation of variable images within metallized and holographic films used in official documents, securities plastic cards, lottery tickets, certificates, tax stamps, diplomas, show tickets, all types of identification, insurance , and in general all kinds of ways valued to avoid fraud, adulteration and forgery.
Cada vez es más imperante la necesidad de contar con elementos contra la falsificación y el fraude en documentos y productos. La falsificación y adulteración se presenta en una gran variedad de artículos, tanto en medicamentos, documentos, tarjetas de identificación, valores, formatos, alimentos, licores, confecciones, calzado, software, fonogramas, video, repuestos, etc. The need for counterfeiting and fraud in documents and products is increasingly prevalent. Counterfeiting and adulteration is presented in a wide variety of articles, both in medicines, documents, identification cards, values, formats, food, spirits, clothing, footwear, software, phonograms, video, spare parts, etc.
Los elementos contra la falsificación son más efectivos y fácilmente reconocibles e identificables por el consumidor y la autoridad, utilizando tecnología que impide la imitación y la copia ilícita. Estas barreras se obtienen mediante el desarrollo permanente de sistemas de alta tecnología fuera del alcance inmediato del falsificador común. Elements against counterfeiting are more effective and easily recognizable and identifiable by the consumer and authority, using technology that prevents imitation and illegal copying. These barriers are obtained by the permanent development of high-tech systems out of the immediate reach of the common forger.
Entre los elementos de seguridad se cuenta con el holograma, el cual genera seguridad en la protección contra la falsificación, debido a la tecnología de punta involucrada en su manufactura, así como del equipo especializado requerido para su fabricación. El holograma es fácilmente identificable por cualquier observador por su tridimensionalidad, sin generar ambigüedad. Motivo por el cual ha desplazado a otros sistemas como son la marca de agua, la impresión intaglio, y el uso de tintas o sustratos especíales, colocándose a la vanguardia en lo que a protección contra falsificación y fraude se refiere. Among the security elements is the hologram, which generates security in the protection against counterfeiting, due to the cutting-edge technology involved in its manufacture, as well as the specialized equipment required for its manufacture. The hologram is easily identifiable by any observer for its three-dimensionality, without generating ambiguity. Reason why it has displaced other systems such as the watermark, intaglio printing, and the use of specific inks or substrates, placing itself at the forefront in terms of protection against counterfeiting and fraud.
La holografía es el único proceso, que genera verdaderas imágenes en tercera dimensión {bidimensionales , tridimensionales, etc.), porque recrea exactamente las ondas de luz (patrón de interferencia) después de reflejarse sobre un objeto real. Todas las características de la luz se graban sobre placas de película fotosensible, mediante montajes ópticos y un láser especifico. Existen hologramas 2D-3D, colorgramas, estereogramas , hologramas con efectos de micro textos, validación con láser tipo apuntador, validación con decodificador, etc. Holography is the only process, which generates true third-dimensional images {two-dimensional, three-dimensional, etc.), because it recreates exactly the light waves (interference pattern) after being reflected on a real object. All the characteristics of the light are recorded on photosensitive film plates, by means of optical assemblies and a specific laser. There are 2D-3D holograms, colorgrams, stereograms, holograms with micro text effects, laser validation type pointer, validation with decoder, etc.
Los hologramas se suministran grabados sobre gran variedad de sustratos, siendo los mas representativos la etiqueta auto-adhesiva en diversos sustratos, tales como papel, poliéster, PVC, polipropileno, materiales intransferibles, para aplicación manual o automática, y las películas de transferencia térmica para aplicación automática haciéndolos aplicables sobre cualquier producto, independientemente del material, tipo de presentación o empaque del que este hecho el articulo a proteger. The holograms are supplied with engravings on a wide variety of substrates, the most representative being the self-adhesive label on various substrates, such as paper, polyester, PVC, polypropylene, non-transferable materials, for manual or automatic application, and thermal transfer films for automatic application making them applicable to any product, regardless of the material, type of presentation or packaging from which the item to be protected is made.
La producción en serie de hologramas conocida mas ampliamente, se efectúa mediante la aplicación de presión y calor en una lámina de metal (sobre la cual existe una imagen holográfica) contra una película plástica metalizada, o recubierto con un dieléctrico transparente. Esto produce los hologramas típicos para la autentificación de todo tipo de productos, que son los más representativos de la industria holográfica. Un nolograma 2D - 3D, es elaborado en dos planos, uno superficial y otro de profundidad, mediante los cuales se produce la sensación de tercera dimensión, en colores arco iris . El avance tecnológico y la permanente investigación relacionada con la protección contra la falsificación, ha hecho que mediante la holografía se puedan obtener varias clases de efectos ópticos fácilmente visibles, asi como otros escondidos o encriptados, los que solo se evidencian mediante ángulos de iluminación específicos y con dispositivos diseñados para tal fin. The series production of holograms known more widely, is effected by the application of pressure and heat on a sheet of metal (on which there is a holographic image) against a metallized plastic film, or coated with a transparent dielectric. This produces the typical holograms for the authentication of all types of products, which are the most representative of the holographic industry. A 2D - 3D nologram is made in two planes, one superficial and one deep, through which the third dimension sensation is produced, in rainbow colors. Technological progress and ongoing research related to protection against counterfeiting, has made it possible to obtain various kinds of easily visible optical effects through holography, as well as hidden or encrypted ones, which are only evidenced by specific lighting angles and with devices designed for this purpose.
Dentro de los efectos visibles se pueden enunciar, el efecto arco iris, el efecto tridimensional, el efecto 2D/3D, el efecto colorgrama, el efecto estereograma, o los obtenidos por medio de matriz de puntos. Los hologramas han demostrado cumplir ampliamente todos los requisitos exigidos por la seguridad contra falsificación y fraude, debido a que son claramente visibles en un amplio rango de condiciones de iluminación. Within the visible effects, the rainbow effect, the three-dimensional effect, the 2D / 3D effect, the colorgram effect, the stereogram effect, or those obtained by means of a dot matrix can be stated. Holograms have been shown to fully comply with all the requirements demanded by security against counterfeiting and fraud, because they are clearly visible in a wide range of lighting conditions.
Para la elaboración o manufactura de un holograma, se elabora el diseño de la imagen deseada con sus correspondientes efectos de seguridad, con lo cual se genera el molde holográfico. Posteriormente se generan las placas de grabado por medio de un proceso de electroforinado, las cuales se montarán en los equipos de grabado para generar las películas o materiales holográficos del ancho y espesor deseado. Todo lo anterior implica que toda modificación requerida sobre el diseño inicial aprobado, generará nuevos costos de generación de moldes holográficos, y la repetición del proceso descrito anteriormente, por lo que se tiene que invertir una cantidad importante de tiempo y recursos. Los hologramas de matriz de punto también apoyan las imágenes de CLR (lectura secreta por láser), donde un dispositivo simple del láser se puede utilizar para verificar la autenticidad del holograma . Procesar imágenes es una tarea matemática complicada que implica solucionar grandes problemas. For the elaboration or manufacture of a hologram, the design of the desired image is elaborated with its corresponding security effects, with which the holographic mold is generated. Subsequently, the engraving plates are generated by means of an electroforming process, which will be mounted on the engraving equipment to generate the holographic films or materials of the desired width and thickness. All of the above implies that any modification required on the design initial approved, will generate new costs of generating holographic molds, and the repetition of the process described above, so you have to invest a significant amount of time and resources. Dot matrix holograms also support CLR (secret laser reading) images, where a simple laser device can be used to verify the authenticity of the hologram. Processing images is a complicated mathematical task that involves solving big problems.
Los hologramas variables son del tipo en donde la información variable es proporcionada por los recubrimientos transparentes y producida mediante láser. Por ejemplo la numeración secuencial alfanumérica en hologramas realza perceptiblemente la seguridad y proporciona facilidad del seguimiento material. La imagen óptica incluye información variable que no puede ser quitada sin su destrucción. La información variable aparece en los colores de esas superficies en las cuales se ponga el holograma. The variable holograms are of the type where the variable information is provided by the transparent coatings and produced by laser. For example, alphanumeric sequential numbering in holograms significantly enhances security and provides ease of material tracking. The optical image includes variable information that cannot be removed without its destruction. The variable information appears in the colors of those surfaces on which the hologram is placed.
En la Patente 7,368,217 de los Estados Unidos, 6 de mayo de 2008, denominada "Imagen de múltiples capas, particularmente una imagen multicolor. La invención se .relaciona con un proceso para la producción de una imagen de múltiples capas, preferiblemente una imagen multicolor. Se utiliza una película de transferencia que se aplica a un substrato de papel y que se trata con la irradiación del láser. La película de transferencia tiene una capa sensible al láser y una capa inferior dispuesta como fondo. La capa sensible al láser comprende por ejemplo pigmentos sensibles al láser u otros agentes colorantes sensibles al láser. Eso da lugar a un componente inducido por láser superpuesto de imagen. Pues es transparente o en parte transparente, la capa del fondo puede tener una imagen impresa que llega a ser visible en esa región. Dando por lo tanto una imagen de múltiples capas formada por el componente de imagen inducida por láser y por la capa de fondo en común. En donde es posible imprimir texto variable. In US Patent 7,368,217, May 6, 2008, called "Multilayer Image, particularly a multicolored image. The invention is It relates to a process for the production of a multilayer image, preferably a multicolored image. A transfer film is used that is applied to a paper substrate and treated with laser irradiation. The transfer film has a laser sensitive layer and a bottom layer arranged as a bottom. The laser sensitive layer comprises, for example, laser sensitive pigments or other laser sensitive coloring agents. That results in an image-induced laser-induced component. As it is transparent or partly transparent, the background layer may have a printed image that becomes visible in that region. Giving therefore a multilayered image formed by the laser induced image component and the background layer in common. Where it is possible to print variable text.
