摘要： The invention is characterized in that it comprises a toolpath generating routine and system for generating a plurality of control points directly from image data representing an image to be engraved. The control points are used to generate a toolpath which, in turn, will be used to energize an engraving head such that a tool or stylus will engrave a pattern of engraved areas in response to the toolpath. An engraving system and method for engraving at least one engraved area is shown having an engraving head tuner for tuning an engraving head such that the frequency characteristic of the engraving head defines a substantially constant gain for frequencies less than a predetermined frequency. The invention is further characterized in that it incudes a system and method for interactively or automatically tuning the engraving head, interactively adjusting the filter characteristics (including the filter coefficients for the filters used on the engraving head) and for being responsive to the type of image data (whether continuous tone data or linework data). The invention is characterized in that it synthesizes the screening function so as to more accurately reproduce the image to be engraved by engraving multiple frequency cells where single cells would be engraved in the past.
