Abstract: The present application relates to a process for manufacturing an article (1) comprising a substrate (3) and a translucent, semi-transparent or transparent overlay (5). The substrate (3) has a contoured surface (7) and the overlay (5) is provided over at least a portion of the contoured surface. The process comprises using a computer system to generate data corresponding to a three-dimensional image. The generated data is used to control apparatus to form at least a portion of a mould for defining the contoured surface (7) of the substrate (3) and the mould is then used to form at least the contoured surface of the substrate. The overlay (5) is then provided over at least a portion of the contoured surface (7). The present application also relates to articles (1) formed by this process.
