An article includes a substrate and a graphical component forming an image and an optical component which includes magnetic pigment flakes aligned so as to form a frame pattern which surrounds the image. When light is incident upon the pigment flakes from a light source, light reflected from the frame pattern forms a dynamic frame which surrounds the image and appears to move as the substrate is tilted with respect to the light source. The image appears to be stationary when the dynamic frame appears to move.

A method of manufacturing a pattern on a substrate web includes providing a production tool having a surface relief structure of elevations and depressions. The elevations correspond to a desired pattern. A curable material is applied to the elevations. The material is brought into contact with a substrate web at a first location. The substrate web and surface relief structure are transported together in contact from the first location to a second location spaced from one another along the transport direction of the substrate web. The substrate web is separated from the surface relief structure at the second location whereupon the material forming the pattern is affixed to and carried by the substrate web. The material is cured by exposure to a curing energy source, either between the first and second locations and/or after the substrate web has been separated from the surface relief structure at the second location.

A display includes one or more first relief structures. Each of the one or more first relief structures consists of a smooth first reflection surface and a plurality of protrusions or recesses, each top surface of the protrusions or each bottom of the recesses is a smooth second reflection surface parallel to the first reflection surface, each of the one or more first relief structures is configured to display a color as a structural color by emitting a plurality of wavelength components of visible light wavelengths in the same direction, and each of the second reflection surfaces has a height or depth relative to the first reflection surface in a range of 0.1 to 0.5 m.

Implementations provide method that includes: accessing data encoding the one or more images sized and shaped for presentation on a square or rectangular surface; providing the first set of data for warping by one or more computer processors such that each of the one or more images is projected onto a respective trapezoidal surface having a first base and a second base that is longer than the first base, wherein the first base is arranged to be closer to a viewer than the second base, and wherein a first portion of each image is projected further away from the viewer than a second portion of each image; and presenting each of the projected one or more images on the respective trapezoidal surface, wherein the first portion of each projected image is presented by the first base and the second portion of each projected image is presented by the second base.

Methods and apparatus provide for an improved visual and optionally tactile features on a visible element of an article, such as a consumer electronic device (e.g., a mobile electronic device, a mobile phone, a smartphone, a tablet, a phablet, a notebook computer, a laptop, etc.).

In a printed article, pigment flakes are magnetically aligned so as to form curved patterns in a plurality of cross-sections normal a continuous imaginary line, wherein radii of the curved patterns increase along the imaginary line from the first point to the second point. When light is incident upon the aligned pigment flakes from a light source, light reflected from the aligned pattern forms a bright image which appears to gradually change its shape and move from one side of the continuous imaginary line to another side of the continuous imaginary line when the substrate is tilted with respect to the light source.

A security document with unidirectional visual illumination is disclosed. A security feature is positioned within the document and not visible in normal ambient lighting conditions but becomes visible under specialized lighting conditions, for example in the presence of ultraviolet light. The security feature is constructible such that it is visible only from a single side of the security document, with the side being predeterminable regardless of the orientation of the specialized light.
