  • Patent number: 4013831
    Abstract: The invention relates to a method for the production of a printing form by the scanning point-by-point and line-by-line of an image pattern along successive cylindrical peripheral image lines and engraving cavities along corresponding cylindrical peripheral engraving lines by an engraving member having an engraving needle as a cutting tool, and includes the steps of generating image signals from the image pattern from along one of the cylindrical peripheral image lines, and engraving a number of cavities at the beginning of an engraving line to depths substantially less than the depths defined by the corresponding image signals.Then the other cavities of said engraving line are engraved to depths which are defined by the nominal values.Subsequently the incomplete cavities of said engraving line are re-engraved in accordance with the corresponding image signals.

  • Patent number: 4013829
    Abstract: A method for the production of a printing form by the scanning point-by-point and line-by-line of an image pattern along successive cylindrical peripheral image lines and engraving cavities along corresponding cylindrical peripheral engraving lines, features the steps of generating scanning image signals from the image pattern from along one of the cylindrical peripheral image lines, reading the image signals into a storage device, reading the stored image signals out of the storage device and coupling the read-out image signals to an engraving device. Then, the engraving with the engraving device is carried out along a cylindrical peripheral engraving line corresponding to the one image line in response to the read-out image signals.
