Abstract
A method is described for producing embossing plates, in particular steel intaglio printing plates. A plane element is determined from a line drawing, the edge of the plane element defining a desired contour. A tool track is then calculated from the desired contour and a desired depth associated with the plane element, to be used for guiding an engraving tool such that the partial area is removed.
Claims35
A method for producing an embossing plate, in particular a steel intaglio printing plate, having at least one depression in the form of a line brought into the surface of the embossing plate, characterized in that the at least one line defines a limited partial area of the surface, the edge of the at least one partial area defining a desired contour, and a tool track located within the desired contour being determined from the desired contour and a desired depth determining the penetration depth of the engraving tool, an engraving tool being controlled along said track such that the material of the partial area is removed within the desired contour at the predetermined desired depth.
An engraved object, in particular a plate such as an embossing or printing plate, having at least one depression in the form of a line brought into the surface by engraving and having flanks and a bottom, characterized in that the depression has a substructure representing additional information and the width of the substructure is smaller than that of the depression on the surface of the object.
An embossing or intaglio printing plate having at least one depression in the form of a line brought into the surface by engraving and having flanks and a bottom, characterized in that the depression has a substructure whose width is smaller than that of the depression on the surface of the object.
