<p>Decorated three-dimensional articles (64, 78, 82, 86) may be produced having wall structure (66-72) with distortion-free images (40a, 40b) appearing through the inner and outer surfaces of the wall structure (66-72). Preferably, a sheet of paper stock (38) is imprinted on both faces with mirror images (40a, 40b), and the stock (38) is applied to a light-transmitting substrate (44) so that the image (40b) appears through the substrate (44), thereby yielding a blank (50). A plurality of lines of weakness (54) are formed in the blank (50) by laser ablation extending through the image (40a) and stock (38), but not through the image (40b), in order to define spaced apart bend areas (56). The substrate (44) is then heated along the bend areas (56), and the blank (50) is formed about a mandrel (62). If desired, the formed blank (50) may be completed by addition of a base (74). The invention can be used for the economical production of a virtually limitless number of three-dimensional articles, even with one-off unique articles or short runs of articles.</p> |
