Abstract
The present invention relates to a method used to engrave chalcographic plates or cylinders, characterised by the fact that plates and cylinders are engraved by means of a laser beam generated by a pulsed laser device with resonance chamber housing a silicon bar with 50 mm length and 4 mm diameter with NewDimium 0.8% doping and convex mirror with 500-mm radius.
Claims8
1) A method used to engrave chalcographic plates or cylinders characterised by the fact that plates and cylinders are engraved by means of a laser beam generated by a pulsed laser device (L) with resonance chamber (R) housing a silicon bar (B) with 50-mm length and 4-mm diameter, with NewDimium 0.8% doping and convex mirror (S) with 500-mm radius.
5) Installation for the engraving of chalcographic plates or cylinders, characterised by the fact that it includes:
- A pulsed laser device (L) with resonance chamber (R) housing a silicon bar (B) with 50-mm length and 4-mm diameter, with NewDimium 0.8% doping and convex mirror (S) with 500-mm radius.
- A first computer (C1) where chalcographic drawings made with computer graphics software are reprocessed in vector data
- A second computer (C2) that receives the vector data from the first computer (C1) through encrypted connection, provided with two electronic boards (S1, S2), respectively used to move the plate or cylinder to be engraved according to two Cartesian axes and to move the head (TS) of the pulsed laser device (L) according to an orthogonal direction to the plane defined by the two Cartesian axes.
