Abstract
An engraving machine for gravure printing to suppress the adverse effect upon the printed image by overshooting of the stylus. The gravure engraving machine has a stylus in an engraving head and controlled by an engraving signal in accordance with an image signal for engraving a surface in a gravure cylinder. An engraving signal generator is provided for generating a carrier signal to drive the stylus, and a modifying signal generator is provided for generating a modifying signal to modify overshoot waveforms caused when the engraving signal is applied to the engraving head. The gravure engraving machine also includes an adder for adding the modifying signal to the engraving signal to modify the engraving signal applied to the engraving head and thereby suppress overshooting of the stylus.
