## Abstract

Provided are methods for making a product having a three-dimensional surface. The method includes providing a base material, providing an adhesive layer and positioning the adhesive layer relative to the base material. The method includes providing a three-dimensional sheet having a top surface and a bottom surface, the top surface having a convex lens layer. The three-dimensional sheet is positioned relative to the base material based on a registration of an image on the three-dimensional sheet and is secured to the base material using the adhesive layer. Securing the three-dimensional sheet to the base material can include applying pressure to the three-dimensional sheet in successive steps of increasing pressure. Also provided is a product having a three-dimensional surface that includes a base material, a three-dimensional sheet, and an adhesive layer disposed between the base material and three-dimensional sheet and configured to secure the three-dimensional sheet to the base material.

## Claims

### Claim 1

A method of making a product having a three-dimensional surface, comprising:
providing a base material;
providing an adhesive layer and positioning the adhesive layer relative to the base material;
providing a three-dimensional sheet having a top surface and a bottom surface, the top surface having a convex lens layer having an array of identical semi-spherical convex lenses each having a focal distance and a special effect layer disposed on the sheet at a selected distance from the convex lenses equal to the focal length of the lenses;
positioning the three-dimensional sheet relative to the base material based on a registration of an image on the three-dimensional sheet; and
securing the bottom surface of the three-dimensional sheet to the base material using the adhesive layer.

### Claim 2 (depends on 1)

The method of claim 1, wherein securing the bottom surface of the three-dimensional sheet to the base material comprises applying pressure to the three-dimensional sheet.

### Claim 3 (depends on 2)

The method of claim 2, wherein applying pressure to the three-dimensional sheet comprises applying pressure in successive steps of increasing pressure.

### Claim 4 (depends on 1)

The method of claim 1, wherein providing the adhesive layer comprises providing an adhesive layer having a release liner, the method further comprising removing the release liner prior to securing the bottom surface of the three-dimensional sheet to the base material using the adhesive layer.

### Claim 5 (depends on 1)

The method of claim 1, wherein the base material comprises one or more of paper, resin, plastic, glass, rubber, metal, or alloy.

### Claim 6 (depends on 1)

The method of claim 1, wherein the base material comprises one or more of polystyrene, polyvinyl chloride, PVC laminated polystyrene, compression laminated polystyrene, compression laminated PVC, polyester, polyolefins such as polyethylene, polypropylene, and the like, ABS, acrylics, epoxies, polyurethanes, or polycarbonates.

### Claim 7

A product having a three-dimensional surface, comprising:
a base material;
a three-dimensional sheet comprising a transparent plate having a top surface and a bottom surface, a focal distance layer printed on the bottom surface of the transparent plate and a non-focal distance layer printed on the top surface of the transparent plate, and a convex lens layer having an array of identical semi-spherical convex lenses each having a focal distance, wherein the convex lens layer is adhered to the top surface of the transparent plate; and
an adhesive layer disposed therebetween the base material and the bottom surface of the transparent plate, wherein the adhesive layer is configured to secure the bottom surface of the three-dimensional sheet to the base material.

### Claim 8 (depends on 7)

The product of claim 7, wherein the base material comprises one or more of paper, resin, plastic, glass, rubber, metal, or alloy.

### Claim 9 (depends on 7)

The product of claim 7, wherein the base material comprises one or more of polystyrene, polyvinyl chloride, PVC laminated polystyrene, compression laminated polystyrene, compression laminated PVC, polyester, polyolefins such as polyethylene, polypropylene, and the like, ABS, acrylics, epoxies, polyurethanes, or polycarbonates.
