## Abstract

Disclosed are printed articles and methods for manufacturing printed articles. The printed articles typically include: (a) a substrate having a top surface and a bottom surface; (b) a graphic image layer comprising a plurality of images printed on at least one surface of the substrate; and (c) a plurality of polygonal lenses printed or formed on at least one surface of the substrate above the graphic image layer, wherein the polygonal lenses are clear, magnifying, convex lenses. The lenses may selectively magnify portions of the array of images to create a plurality of images that appear and disappear or images that float under or on top of the graphic image when viewed from different perspectives.

## Claims

### Claim 1

A printed article comprising:
(a) a substrate having a top surface and a bottom surface;
(b) a graphic image layer comprising a plurality of images printed on at least one surface of the substrate; and
(c) a plurality of polygonal lenses printed on at least one surface of the substrate above the graphic image layer, wherein the polygonal lenses are clear, magnifying, convex lenses;
wherein the printed lenses have a height of between 0.0001-0.001 inches, a width from a top planar view between 0.0001-0.01 inches, and spacing between the lenses is between 0.001 to 0.01 inches.

### Claim 2

A printed article comprising:
(a) a substrate having a top surface and a bottom surface;
(b) a graphic image layer comprising a plurality of images printed on at least one surface of the substrate;
(c) a transparent layer formed on at least one surface of the substrate above the graphic image layer; and
(d) a plurality of polygonal lenses formed on the transparent layer above the graphic image layer, wherein the polygonal lenses are clear, magnifying, convex lenses;
wherein the printed lenses have a height of between 0.0001-0.001 inches, a width from a top planar view between 0.0001-0.01 inches, and spacing between the lenses is between 0.001 to 0.01 inches.

### Claim 3

A printed article comprising:
(a) a transparent substrate having a top surface and a bottom surface;
(b) a graphic image layer comprising a plurality of images printed on the bottom surface of the substrate; and
(c) a plurality of polygonal lenses printed on the top surface of the substrate, wherein the polygonal lenses are clear, magnifying, convex lenses;
wherein the printed lenses have a height of between 0.0001-0.001 inches, a width from a top planar view between 0.0001-0.01 inches, and spacing between the lenses is between 0.001 to 0.01 inches.

### Claim 4

A method of forming a printed article, the method comprising:
(a) printing a graphic image layer comprising a plurality of images on at least one surface of a substrate; and
(b) printing a plurality of polygonal lenses on at least one surface of the substrate above the graphic image layer, wherein the polygonal lenses are clear, magnifying, convex lenses;
wherein the printed lenses have a height of between 0.0001-0.001 inches, a width from a top planar view between 0.0001-0.01 inches, and spacing between the lenses is between 0.001 to 0.01 inches.

### Claim 5

A method of forming a printed article, the method comprising:
(a) printing a graphic image layer comprising a plurality of images on at least one surface of a substrate;
(b) coating the graphic image layer with a transparent layer; and
(c) forming a plurality of polygonal lenses on the transparent layer, wherein the polygonal lenses are clear, magnifying, convex lenses;
wherein the printed lenses have a height of between 0.0001-0.001 inches, a width from a top planar view between 0.0001-0.01 inches, and spacing between the lenses is between 0.001 to 0.01 inches.

### Claim 6

A method of forming a printed article, the method comprising:
(a) printing a graphic image layer comprising a plurality of images on at least one surface of a substrate; and
(b) printing a plurality of polygonal lenses on at least one surface of the substrate above the graphic image layer, wherein the polygonal lenses are clear, magnifying, convex lenses;
wherein the printed lenses are arranged in parallel rows and the method further comprises adjusting orientation θ of the parallel rows to prevent flooding during printing of the lenses.

### Claim 7

A method of forming a printed article, the method comprising:
(a) printing a graphic image layer comprising a plurality of images on at least one surface of a substrate;
(b) coating the graphic image layer with a transparent layer; and
(c) forming a plurality of polygonal lenses on the transparent layer, wherein the polygonal lenses are clear, magnifying, convex lenses;
wherein the printed lenses are arranged in parallel rows and the method further comprises adjusting orientation θ of the parallel rows to prevent flooding during printing of the lenses.
