Abstract
A virtual, real-time proofing system and method are shown. The system and method are characterized in that a reconstructed image of a plurality of engraved cells is created using a pixel data signal that is created using a tool path position signal generated by a sensor that senses the movement of a cutter or stylus as it is engraving the cells.
Claims146
A proofing system for proofing an image engraved on a gravure cylinder;
- at least one sensor for sensing movement of a cutter or cutter holder during engraving of a plurality of engraved cells in response to a source image file associated with a source image and for generating a tool path position signal in response thereto;
- a tool path proofing circuit for receiving said tool path position signal and for generating a pixel data signal in response thereto;
- and
- an engraver tool position reconstructed image generator analysis computer for generating an engraver tool position reconstructed image in response to said pixel data signal;
- said engraver tool position reconstructed image being adapted to be compared to said source image file in order to proof the accuracy of the engraving by said cutter.

A method for proofing an engraved job on a cylinder engraved by a gravure engraver, said method comprising the steps of:
- generating a tool path position signal in response movement of at least one of a cutter or a cutter holder while said cutter is engraving a plurality of engraved cells to provide the engraved job associated with a source image;
- generating a pixel data signal in response to said tool path position signal;
- generating an engraver tool position reconstructed image in response to said pixel data signal;
- and
- comparing said engraver tool position reconstructed image to a source image file in order to proof the accuracy of the engraving by said cutter.
2 more elements
A method for proofing an engraved cylinder, said method comprising the steps of:
- engraving the cylinder with an engraved job corresponding to a source image and substantially simultaneously gather tool path position signal associated with a movement of at least one of a stylus or a stylus holder that holds said stylus while engraving a plurality of cells for said engraved job;
- generating an engraver tool path position reconstructed image using said tool path position signal;
- comparing said engraver tool path position reconstructed image to said source image and identify differences;
- and
- determining whether any differences are within or outside acceptable tolerances in order to proof the accuracy of the engraved job engraved on the engraved cylinder.
