  • Patent number: 9168730
    Abstract: A method of partially imaging a substrate, for example glass, with a print pattern comprising layers of ceramic ink in substantially exact registration. The method relies on a mask ink layer defining the print pattern and differential thermal expulsion of ceramic ink medium during a heat fusing process between the areas outside the print pattern and within the print pattern. This results in pigment and glass frit forming a durable image material adhered to the substrate within the print pattern and non-durable material outside the print pattern, enabling its removal outside the print pattern to leave the desired layers of ceramic ink within the print pattern in substantially exact registration.

  • Patent number: 8832980
    Abstract: An assembly includes a flexurally deformed panel, which is connected to a membrane tie by a linear connector and is tied by the membrane tie to form a geometrically stable pre-stressed structure. More than one panel may be flexurally deformed and tied together in an assembly and more than one membrane tie may be present within an assembly. Panels are typically semi-rigid sheet materials, for example metal sheets, plastic sheets, or sheets of composite materials, such as glass or carbon fiber reinforced plastics or resins. Membrane tie members are typically flexible, for example plastic films, fabrics or nets or arrays of rods or cables. The assemblies have many different geometric forms and many different practical applications. Assemblies may be relatively large, for example demountable and reusable shelters or flat-pack point-of-purchase display assemblies, or may be relatively small, for example a photograph or postcard display system.

  • Patent number: 8784932
    Abstract: A glass panel is partially printed with a plurality of layers in the form of a print pattern which subdivides the panel into a plurality of discrete printed areas and/or a plurality of discrete unprinted areas, the layers being in substantially exact registration. Exact registration is achieved by the application of a plurality of superimposed layers to a sheet of glass. One layer contains-ceramic ink comprising glass frit. The glass sheet and layers are subjected to a heat treatment process which causes the glass frit to fuse to the glass and bind at least one other layer of ink within the print pattern. Ink outside the print pattern is burnt off and/or vaporised during the heat treatment process and/or removed by a subsequent finishing process, to leave the desired layers in substantially exact registration within the print pattern.

  • Patent number: 8500268
    Abstract: This invention concerns vision control panels and a method of UV inkjet printing vision control panels. A substantially imperforate light permeable material is partially printed with a ‘print pattern’ comprising a base layer and a design layer comprising a design colour layer. The method is limited to digital UV inkjet printing of all the superimposed layers required to make such panels. Optionally, the method uses a novel printhead array with a novel order of ink color supply and/or novel software to enable the required build-up of ink layers, for example of black, optional silver, white, cyan, magenta, yellow and process black colors. Printing is preferably arranged so that the base layer and design color layer are printed in the minimum number of passes of the printhead assembly of the digital UV inkjet printer to achieve the desired effect, preferably in one pass of the printhead assembly.

  • Patent number: 8136278
    Abstract: An electroluminescent (EL) one-way vision, see-through graphics panel comprises a sheet of light permeable material with a uniform electrically conductive coating. A print pattern comprising an electroluminescent ink system partially covers the sheet of light permeable material forms an ‘EL lamp’. A design is superimposed on, or forms part of, the print pattern such that the design is visible from only one side of the panel. The design can be a uniform color, but is typically a multi-color graphic image. The EL lamp illuminates the design when subjected to an electrical current. If the light permeable material is transparent, through vision is possible from the other side of the panel through the unprinted portions of the transparent material. A dark colored opaque mask layer faces in the direction of the other side of the panel to mask the other print pattern layers and enable good through vision.

  • Patent number: 8065829
    Abstract: A sign assembly includes a base material, a filmic substrate imaged with a design, and a sign assembly frame that includes a sign framing member of fixed position in relation to the base material. The sign framing member includes a projecting portion terminating at an inside edge of the sign framing member. The display sign is adhered to the base material. The inside edge of the sign framing member is located within the projected area of the display sign and is spaced from the base material and the filmic substrate. The display sign is capable of being applied through an opening defined by the inside edge of the sign framing member. The space between the inside edge of the projecting portion and the display sign includes a void.

  • Publication number: 20090025869
    Abstract: A method of making a vision control panel includes cutting film material in a cutting pattern that includes a plurality of elongate film areas and a plurality of removable elongate film areas. The plurality of removable elongate film areas are optionally connected by a removal connector area. The method also includes separating the plurality of removable elongate film areas from the plurality of elongate film areas by means of an adhering surface, for example by using a removal connector area and/or adhesive tape. The method further includes applying a cut film pattern to a sheet of light permeable material, typically a transparent material, to form a vision control panel. Optionally, two vision control panels are made using alternate elongate film areas and removable alternate elongate film areas, from a single area of self-adhesive film.
