ABSTRACT:
Method and apparatus for producing a design on a flat surface by etching and/or selective plating. The design is transferred to the flat surface by progressively projecting successive narrow transverse images of the design from a rectangular transparency and progressively rotating the flat surface about an axis such that the narrow images of the design are successively projected upon and received by corresponding radial portions of the flat surface which is or has been photosensitized. The design appears on the flat surface in a foreshortened circular form. The flat surface is adapted for subsequent formation into an arcuate surface bearing the design in relatively undistorted form.
