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. 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.
