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. The engraving device is moved to a succeeding cylindrical peripheral engraving line, the read-out of said image signals and the engraving of cavities are inhibited at least during the time said engraving device is being moved to the succeeding engraving line, continuing the read-out and engraving of said succeeding engraving line at the stored image signals or cavities marking the end of the moving of said engraving device and in that, when the end of the engraving line is reached, the first portion of it, which was previously omitted, is engraved retrospectively and the next movement of the engraving device to the succeeding engraving line takes place.
