ABSTRACT:
This disclosure is concerned with an optical printer for making 3D and animation pictures from a plurality of 2D images on a lenticular print material. The 2D images are sequentially projected by a projection lens onto the print material at different projection angles. In order to change the projection angles, the print material and the projection lens are moved relative to the film to different positions. The method and apparatus, according to the present invention, use a tilting mechanism to tilt the print material about an axis parallel to the longitudinal axis of the lenticules and away from the optical axis of the projection lens so as to reduce the moving distance of the print material and the projection lens. In effect, the angular coverage of the printer is extended by the tilting of the print material and, therefore, the printer can make 3D and animation pictures on a print material having a wider viewing angle.
