    摘要: A method and device for producing a permanent as well as erasable image on a printing plate, in particular within a printing press, is disclosed. A printing plate with a rewritable and erasable surface is made available. The surface of the printing plate made available is erased and a permanent and erasable image is created on the erased surface. Following the erasing of the surface, the surface is imaged, gummed and fixed, namely in such a way that, on the one hand, the imaging and the gumming and the fixing occur relative to the erasing in a chronologically sequential and spatially sequential manner, and that, on the other hand, the imaging and the gumming and the fixing each occur relative to one another in a chronologically parallel but spatially sequential manner.

    摘要: A printing press and a method for operating the printing press is disclosed. The press has at least one printing unit including at least one printing couple with a transfer cylinder, a form cylinder carrying an imageable and de-imageable printing form, an inking couple and a dampening unit. A memory is assigned inside the printing press to at least one printing unit having several memory locations for form cylinders, where the form cylinders for the printing units can be transferred automatically by at least one transport device between a printing couple of the printing unit and a memory location of the memory, where the form cylinders can be transferred automatically inside the memory between the various memory locations, and where an imaging device is assigned to at least one memory location to image and de-image in advance an imageable and de-imageable printing form positioned on a form cylinder.

    摘要: A method and apparatus for applying a medium, especially a conditioning medium or a rubber covering medium, to a printing form positioned on a form cylinder, especially to a rewritable and erasable printing form, is disclosed. The medium is applied to a rubber covered cylinder or to a separate applicator roll or an applicator cylinder for the medium, the medium then being transferred from the rubber covered cylinder or applicator roll or applicator cylinder to the form cylinder, in this case the rubber covered cylinder, the applicator roll or the applicator cylinder rolling repeatedly over the form cylinder in order to ensure a uniform application of the medium to the printing form.
