Abstract: A partially perforated assembly includes a perforated film layer, a perforated adhesive layer applied to one side of said film layer, a non-perforated overlaminate film layer on the other side of said perforated film layer, and a release liner on the side of said perforated adhesive layer remote from said perforated film layer. When the release liner is removed and the remaining layers of the assembly are applied to a substrate, the remaining layers of the assembly comprise a void network. The void network fluidly interconnects at least two discrete perforation holes in the perforated film and adhesive layers with each other and/or the ambient environment around the assembly so as to facilitate air communication among the holes and/or between the holes and the ambient environment.

Abstract: An open perforated assembly typically includes a film layer (26) on one side of the open perforated assembly, and an adhesive layer (32) and a release liner (42) on the other side. The layers and liner are perforated with a plurality of holes (6). The assembly is devoid of any imperforate layer. The perforated liner has a first color visible from the other side. Upon removal of the perforated release liner the appearance of the assembly from the other side is similar to the appearance before removal of the perforated liner. The assembly may be imaged by digital inkjet printing using a digital inkjet machine. Its printheads are spaced from one side of the open perforated assembly and an ink receiving surface (62) is located on the other side such that ink that is jetted from the printheads and passes through the holes in the open perforated assembly is deposited on the ink receiving surface.

Abstract: A method of manufacturing a part of a device including a first part and a second part which are inter-engageable with one another, the first part having a first longitudinal axis and a connecting face which extends substantially transversely to the first longitudinal axis and includes an engagement formation which extends substantially axially, and the second part having a second longitudinal axis and a connecting face which extends substantially transversely to the second longitudinal axis and includes a receiving formation which extends substantially axially and in which the engagement formation of the first part is receivable, wherein each of the engagement formation and the receiving formation includes a substantially helicoidal surface which extends at least partially around the longitudinal axis of the respective part of the device, such that rotation of the two parts relative to one another about the longitudinal axes, when the two parts are substantially co-axially aligned, such that the connecting fa

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.

Abstract: A perforated self-adhesive film assembly capable of being imaged includes a perforated face film; a perforated adhesive layer; a perforated liner, each of the perforated face film, perforated adhesive layer, and perforated liner being perforated with a plurality of holes; and a removable non-perforated bonding layer removably attached to the perforated liner. The removable bonding layer includes a bonding surface. The bonding surface includes one or more of the following: i) a surface topography with a difference between the height of a peak and the depth of a trough within one of said plurality of holes of not less than 5 micron, ii) an adhesion enhancing surface coating, or (iii) a surface spaced from said perforated liner around the complete perimeter of one of said plurality of holes.

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.

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.

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.

Abstract: An apparatus and method for making a panel with superimposed layers of marking material in substantially exact registration is provided. An assembly includes a stencil layer sandwiched between a substrate and a transparent coating. The stencil includes a release surface. The coating tends to secure the stencil layer to the substrate, e.g., for storage and/or transport, and may protect the stencil layer from marking materials that might otherwise penetrate the stencil layer. A design and background layers are then printed onto the coating. A force is then applied to remove the background layer, design layer, and coating that are disposed on the stencil layer, leaving the remainder of the background layer, design layer, and coating adhered to the substrate in substantially exact registration within portions of the substrate that are devoid of the stencil layer. The design layer is right-reading visible through the substrates.
