Abstract
A method for manufacturing a visual display assembly, comprising: providing a film of transparent material comprising a first surface and a second surface opposite the first surface, the first surface comprising an array of lenses comprising information that is arranged so as to be capable of providing multiple images when the images are viewed from different predetermined angles through the lenses; placing a screen-printing fabric in proximity to the first surface in order to form a pattern or printed image; applying a layer of ink or varnish to the screen-printing fabric allowing the ink or varnish to pass through for placement on a portion of the first surface; wiping the ink or varnish by means of a squeegee over the screen-printing fabric.
Claims21
A method for manufacturing a visual display assembly, characterized in that the method comprises:
- providing a film of transparent material comprising a first surface and a second surface opposite the first surface, wherein only the film of transparent material is between the first surface and the second surface and wherein the film of transparent material is a single substrate, the first surface comprising an array of lenses arranged so as to be capable of providing multiple images when the multiple images are viewed from different predetermined angles through the lenses;
- placing a screen-printing fabric in direct contact with the first surface, the screen-printing fabric comprising a deposit portion and a capillary film portion, wherein the screen-printing fabric including between 71 and 120 threads per cm, and wherein the screen-printing fabric is colored to block diffusion phenomena;
- applying a layer of ink or varnish including at least a gelling agent and a silicone-type tensioning agent to the screen-printing fabric, wherein the deposit portion allows passage of the ink or varnish for placement on a portion of the first surface in order to form a pattern or a printed image on the first surface and the capillary film portion prevents ink or varnish from passing through the screen-printing fabric, wherein the layer of ink or varnish includes a thickness that extends outward from the first surface and away from the second surface, and wherein the second surface is flat and free of ink, varnish, and images;
- and
- wiping the ink or varnish by means of a squeegee over the screen-printing fabric so that the pattern or the printed image includes a generally planar top ink surface that is substantially parallel to the second surface.
A visual display assembly comprising:
- a film of transparent material comprising a first surface and a second surface opposite the first surface, wherein only the film of transparent material is between the first surface and the second surface and wherein the film of transparent material is continuous, the first surface comprising an array of round-based or square-based lenses arranged so as to be capable of providing multiple images when the multiple images are viewed from different predetermined angles through the array of round-based or square-based lenses;
- and
- a screen-printed image or a pattern that covers a portion of the first surface, wherein the screen-printed image or the pattern is printed with a layer of ink or varnish by pressing the ink or varnish through a screen-printing fabric, the ink or varnish including at least a gelling agent and a silicone-type tensioning agent, wherein the screen-printed image or the pattern includes a top ink surface that is generally planar and substantially parallel to the second surface of the film of transparent material, wherein the screen-printing fabric is colored to block diffusion phenomena, and wherein the second surface is flat and free of ink, varnish, and images.
