Abstract
Abstract Methods and apparatus for producing autostereograms using ultraviolet radiation-curable thermosetting polymers. A stereoscopic image is printed upon a plastic or paper sheet, which is fed directly onto a surface having an inverse lenticular pattern relief. As the sheet is fed onto the surface, a flow of ultraviolet-curable thermosetting polymer resin is directed at the surface. Ultraviolet radiation is directed at the polymer layer, curing the polymer and forming a lenticular array on the front surface of the polymer layer. During this process, the sheet carrying the stereoscopic image is bonded to the back surface of the polymer lenticular layer in precise registration with the lenticular array. In a preferred embodiment of the invention, the inverse lenticular pattern relief is on the outer surface of a transparent cylinder. The polymer layer is cured as it is flowed onto the relief pattern by an ultraviolet lamp placed within the transparent cylinder.
