Abstract: A partially printed substrate with a print pattern comprising a first color deposited on the substrate and a second color deposited on the first color, the second color being darker than the first color, whereby the first and second colors are perceived as a combined, substantially single color in the area defined by the first color.
Abstract: A method of imaging a substrate is disclosed, the method consisting of applying a first layer to the substrate to form a “print pattern” and a second step of presenting an “addressed design” to the substrate both within an outside the area of the print pattern. In the method of the invention, within the print pattern the addressed design is formed into a “durable image material” forming at least a part of the design layer and outside the print pattern, the addressed design does not form a durable image material.
Abstract: A panel includes a sheet of light permeable, preferably optically clear transparent material and a transparent or translucent design superimposed on or forming part of a transparent or translucent base pattern. The design is visible from one side of the panel and a mirror image of the design is visible from the other side of the panel when a sufficiently high level of illuminated is provided on either side or both sides of the panel.
Abstract: A partially printed substrate with a print pattern comprising a first color deposited on the substrate and a second color deposited on the fist color, the second color being darker than the first color, whereby the first and second colors are perceived as a combined, substantially single color in the area defined by the first color.
Abstract: A method of printing a number of superimposed or otherwise geometrically related layers on a substrate with exact registration which comprises printing said layers over one or more areas on said substrate so as to overlap the boundary of said one or more areas and then removing the layers outside said areas. The product produced by the method and the intermediate product prior to removal of layers outside the areas can be used for security purposes.
Abstract: A panel which comprises a substrate of transparent or translucent material having applied to one or both sides a design superimposed on, or forming part of, an opaque pattern so that the design on one side of the panel cannot be seen from the other side.
