Problems solved by technology

Typically, for element 200, the microlenses are printed using an emboss and fill technique, which limits printing to one color due to the fact that the process is prone to self-contamination after one color, and also due to the The fact that the process has difficulty controlling the relative color-to-color spacing in embossing and infill printing processes

Embodiment Construction

[0044] Briefly, this description is directed to the design of the components of the lens array used in combination with the printed image provided in the ink layer. The component can be used as, for example, but not limited to, an anti-counterfeiting element or device. Lens array and figure 1 with figure 2 The lens array shown in is partially different because the lenses are arranged in columns that are not vertically offset, so that the lenses are provided in parallel columns and also in parallel rows (for example, adjacent ones in side-by-side columns). The lenses are aligned to their collinear center axis). The lens may be a lens based on a circle, a square, a parallelogram, or a hexagon, and the lower image has its pixels mapped and arranged such that the microlens array produces a 3D display image with a full volume, and in some cases has Multi-directional movement or animation.

[0045] in Figure 3A with Figure 3B In the illustrated embodiment, the item 300 (such as ba...

Abstract

A visual display assembly adapted for use as an anti-counterfeiting device on paper currency, product labels, and other objects. The assembly includes a film of transparent material including a firstsurface including an array of lenses and a second surface opposite the first surface. The assembly also includes a printed image proximate to the second surface. The printed image includes pixels of frames of one or more images interlaced relative to two orthogonal axes. The lenses of the array are nested in a plurality of parallel rows, and adjacent ones of the lenses in columns of the array arealigned to be in a single one of the rows with no offset of lenses in adjacent columns / rows. The lenses may be round-based lenses or are square-based lenses, and the lenses may be provided at 200 lenses per inch (LPI) or a higher LPI in both directions.

Description

[0001] This application is a divisional application of an invention patent application with an application date of February 27, 2014, an application number of 201480060437.2, and an invention title of "Pixel Mapping and Printing for Microlens Arrays to Realize Biaxial Activation of Images". [0002] Cross references to related applications [0003] This application is a partial continuation application of U.S. Patent Application No. 14 / 017,415 filed on September 4, 2013. The U.S. patent application requires the rights of U.S. Provisional Application No. 61 / 743,485 filed on September 5, 2012. Both applications are incorporated herein by reference in their entirety. Technical field [0004] The present invention generally relates to combining a printed image with a lens array to display a three-dimensional (3D) image with or without motion, and more specifically, to a method suitable for use with squares, circles, parallelograms, or hexagons. Arrays of microlenses are used together to...
