Patent ID: 6840721

Claim:
A method for producing an intaglio printing plate having a flat top surface with at least one depression in the form of a line brought into the surface of the intaglio printing plate and arranged to be filled with printing ink during intaglio printing, comprising the steps of: providing a two-dimensional line original; defining from the two-dimensional line original a line to be brought into the surface of the intaglio printing plate, said line defining a limited partial area, an edge of the limited partial area defining a desired contour; associating a depth profile, selected based on the amount of printing ink to be used in printing, within the desired contour; calculating track data with aid of a computer program for controlling movement of an engraving tool along a tool track to be followed by the engraving tool within the desired contour based on the desired contour and the predetermined desired depth profile; and controlling the movement of the engraving tool along said tool track according to said track data such that a material of the surface of the intaglio printing plate is removed within the desired contour along the predetermined desired depth profile to form said at least one depression, said tool track being continuous.
