Abstract
An engraver having an engraving signal generating system for engraving a workpiece. The engraver includes a setup circuit enabling direct dimensional control of the cavities engraved by the engraver. Controls are provided for setting at least one of a plurality of parameters, such as a black cell width. These parameters are fed to the setup circuit which translates them into multiplication factors for an AC signal and a videosignal. The multiplied signals are combined with an offset signal to produce an engraving signal.
Claims24
An engraving signal generating system for use on an engraver comprising:
- input means for inputting a plurality of engraving parameters;
- and
- processing means for suing said plurality of engraving parameters to generate an engrave drive signal in response thereto, wherein said processing means generates a gain for adjusting an amplifier.
An engraving system for engraving a plurality of engraved areas on a workpiece comprising:
- an engraver responsive to engraving drive signals for engraving said workpiece;
- and
- an engraving signal generator coupled to said engraver for receiving engraving parameters and for configuring said engraving drive signals, wherein said plurality of engraving parameters correspond to at least once cell;
- and
- wherein said processing means generates a gain for adjusting an amplifier.
