ABSTRACT:
An error detection apparatus and method for use with engravers, such as gravure engravers. An error value E corresponding to the difference between a set of predetermined setup parameters and actual measurement of a portion of an engraved area on the cylinder is determined. The error value E is then used to adjust the engraver to engrave an actual cut or etch in accordance with the set of predetermined setup parameters. The error detection and correction system a closed-loop system for engraving a cylinder. The apparatus and method may be used during initial setup or during normal operation of the engraver. A method is disclosed comprising the steps of engraving ink receptive cells in the surface of a rotating gravure printing cylinder consisting of the steps of generating a cell width command signal comprising a series of cell width commands, engraving the cells by using the cell width command signal to urge an engraving stylus into periodic engraving contact with the surface, measuring actual widths of cells which have been engraved as aforesaid, and adjusting the cell width command signal in correspondence with differences between the actual widths and the cell width commands.
