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 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: An assembly includes a light-permeable film layer, a release liner, and a print pattern. The print pattern includes a base layer. The print pattern sub-divides the film layer into a plurality of discrete base layer areas and/or a plurality of transparent areas. The base layer includes a design imaging surface of a first color. The release liner includes an imperforate material. The release liner includes a release surface. The imperforate material when viewed through said light permeable film layer is a second color contrasting with said first color by the graytone of said second color differing from the graytone of said first color by at least 10%. This contrast may provide a more realistic perception of how the assembly will look in situ (e.g., on a window).

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 fibre 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.

Abstract: An alternating sign assembly includes a sheet of light permeable material comprising a front surface and a rear surface; a front design that includes a front design layer; a silhouette pattern including light-restricting imaging material, said front design being superimposed on or forming a part of the silhouette pattern, said silhouette pattern subdividing said sheet into a plurality of discrete areas of said imaging material and/or a plurality of discrete areas devoid of said imaging material; a switchable front source of artificial illumination of said front design; a rear design disposed rearwardly of the front design; and a switchable rear source of artificial illumination of said rear design. The sources of illumination may be alternately turned on to make the front and rear designs alternately visible to an observer in front of the assembly.

Abstract: This invention relates to the printing of a substrate having a pre-printed “print pattern” with a “design layer” of ink where there is differential adhesion within and without the print pattern. The print pattern is receptive to an ink, and the design layer ink forms a durable image material with good bond to the print pattern, but the ink does not form a durable image material on the portions of the substrate outside the print pattern. The design layer ink is a UV-curable ink, and the print pattern may have a higher surface energy than the portions of the substrate outside the print pattern.
