Definitions

  • the present descriptive report refers to an application for a patent of invention relative to a process for printing security graphics on laminar elements, the obvious finality of which is to achieve the printing of graphics using inks of all types, incorporating the image on the inner side of two superimposed sheets adjacent to an opaque, translucent, or transparent sheet of plastic, synthetic or cellulose based or not nature, leading to the creation of a three-layered paper in which the imprint of the graphics can only be visualised using transparency, UV light or by the use of a magnetic reader, which will detect the graphics.
  • This invention finds application within the industry dedicated to the manufacture of equipment, devices and security elements applicable on laminar elements.
  • the process for printing security graphics on laminar elements object of the invention comprises performing, on the back of a sheet of paper, consecutive impressions of the graphics using opaque white ink or other covering colours, having luminescent components reactive under the effect caused by UV light, under magnetic effects or having thermovariable reagents, so that, when the sheet is observed against the light, the opaque white ink, or that made of other covering colours, decreases the transparency of the overall set, giving rise to an effect similar to that of conventional watermarks, due to the fact that the impression can be carried out in woven half-tones and consequently gentle Patoscuro effects can be obtained.
  • the invisible impression turns visible, returning to its original state when the laminar support cools down.
  • the printing can also be performed with a colourless fatty ink, which will render the sheet of paper transparent, and due to the incorporation of this type of ink which has a fatty nature, luminescent components reactive to UV light, to magnetic tests or thermovariable reagents can also be incorporated, so that, when the sheet is observed against the light, the fatty ink has increased the transparency of the overall set, and an effect equal to that of a watermark is achieved, as the impression can also be carried out in woven half-tones and, consequently, as in the previous case, gentle Patoscuro effects are obtained.
  • the invisible print becomes visible, returning to its original state when the laminar support cools down.
  • the images will be positioned on the back of one of the two sheets, subsequently laminating upon a central support constituted by an opaque, translucent or transparent sheet manufactured out of a plastic, cellulose-based or synthetic material, such as polyester, vinyl, PVC, etc., etc.
  • the process permits the incorporation of security graphics, giving rise to a laminar support, constituted in a similar manner as the one described earlier, eliminating the incorporation of graphics on the inner side of one of the two laminar elements manufactured in paper, i.e. only one of the paper laminar elements will bear graphics or impressions on its inner side, said graphics being adjacent to the central support, the latter in turn bearing on its opposite side the same paper laminar element.
  • Another solution permits the incorporation of security graphics, both on the inner sides of the laminar elements as well as on the outer side of the central support.
  • a last solution permits the impression of security graphics on the internal faces of the paper sheets, eliminating in this case the central support, thus resulting in the two sheets of paper being adjacent to each other.
  • the graphics may be on one or on both sheets of paper.
  • Figure 1 Corresponds to a side elevational view of a laminar support obtained by the process for printing security graphics on laminar elements object of the invention, which represents the option in which both sheets of paper are printed on their inner faces and are subsequently laminated on a central support.
  • Figure 2. Shows a similar view to that represented in figure number 1, depicting a second embodiment of the invention in which the security graphics are only incorporated on one of the laminar elements.
  • Figure 3. Shows a similar view of the option in which security graphics can be printed both on the internal faces of the laminar elements as well as on the outer face of the central support.
  • Figure 4 represents the option in which the central support disappears, being the security graphics only printed on the internal faces of the laminar elements.
  • a laminar support configured from two sheets of paper (2) and (2'), between which a central support (opaque, translucent or transparent) (4) of plastic, cellulose-based or synthetic material may or may not be incorporated.
  • the internal face of each of the these laminar elements (2) and (2') is imprinted with the graphics, using visible, invisible, opaque, transparent, magnetic, non-magnetic, thermoreactive, non-thermoreactive, light-sensitive or light-insensitive inks, and considering that the images so configured, or graphics (3) and (3') are positioned on their internal faces, they are superimposed adjacent to the central support (opaque, transparent or translucent) of a plastic, synthetic or cellulose-based nature, consequently achieving the creation of a three-layered paper in which the impressions (3) and (3') performed on the external sheets (2) and (2') can only be visualised by transparency, by UV light, or be detected by means of a magnetic reader.
  • a support (10) is obtained, configured as a three-layered paper, in which, the impression performed (12) is carried out on the back or inner face of a sheet of paper (11) placing the sheet of paper (11) at the side bearing the graphics or images (12) adjacent to and upon a central support (opaque, translucent or transparent) (13), in which, on the opposite face, it will be bound to another sheet of paper (11'), which bears no graphics on its faces, external or internal.
  • a support (10) is obtained, configured as a three-layered paper, in which, the impression performed (12) is carried out on the back or inner face of a sheet of paper (11) placing the sheet of paper (11) at the side bearing the graphics or images (12) adjacent to and upon a central support which is opaque, translucent or transparent (13), on which graphics are also printed (12), which, on the opposite face, will be bound to another sheet of paper (11'), which bears no graphics on its faces, external or internal.
  • a support (10) is obtained, configured as a two-layered paper, in which, the impression performed (12) is carried out on the inner face of one or of the two sheets of paper (11) and (11'), eliminating the central support.
