ABSTRACT:
The engraving method and apparatus provides a method and apparatus for engraving a plurality of cells in a surface of a cylinder. The engraving method and apparatus involves, among other things, processing a plurality of image data; modifying at least a portion of the image data and generating a signal corresponding thereto; and then exciting an engraving device in response to the signal in order to engrave a pattern of engraved areas. The engraving method and apparatus facilitate adjusting a characteristic of at least one of said plurality of engraved areas in order to change a spatial relationship between said at least one of said plurality of engraved areas and another of said plurality of engraved areas to provide, for example, a non-regular or non-periodic spacing of engraved areas. The engraving method and apparatus provides a shaping data generator for generating shaping data to be used to modify the image data corresponding to an area to be engraved to redefine at least a portion of said data to provide an engraved area having a desired shape.
