Definitions
- the invention relates to a method for generating print image information load-bearing printing form on a printing form cylinder in a printing press.
- the xerox copying process is generally known. With this copying process a latent image is generated on a semiconductor drum, this image by means of a powdered toner on the paper sheet and erased the latent image. In This method is not applicable to printing presses.
- the object of the invention is to provide a method for generating an erasable Printing form on the printing form cylinder in a printing press with little effort and long service life.
- the printing form cylinder 1 shows a printing form cylinder of a printing press.
- the printing form cylinder 1 is equipped with a semiconductor surface 2, the semiconductor surface 2 expediently having hydrophilic properties.
- the semiconductor surface 2 is provided with image-bearing areas 3 from a previous print job, the image-bearing areas being hydrophobic.
- the new image-bearing points 3 'of a new print job are polarized by means of a polarization device 6.
- Polarization means that the polarized points 5 are made receptive to the toner 7 to be applied later.
- the polarization device 6 is connected to a storage device (not shown) for the digital matrix of the image-bearing points.
- the polarization device 6 is arranged traversing or extending over the entire width of the printing form cylinder 1.
- the semiconductor surface 2 is of the printing form cylinder 1 toner 7 applied.
- the toner 7 is preferably powdery, but can also be pasty or liquid.
- the toner 7 adheres to the polarized points 5 the toner cannot adhere to the non-polarized areas 8, i. H. these positions remain vacant of toner.
- the toner 7 is applied by means of an application device of toner 9. This device, like the polarization device, is traversing or over arranged the entire width of the printing form cylinder 1.
- the last process section is shown in FIG. 4.
- a consolidation device 10 By means of a consolidation device 10 become the toner particles adhering to the polarized points 5 of the semiconductor surface solidified.
- the solidified toner particles are now identical to the image-bearing ones Digits 3 '.
- the printing form is for the printing process prepared.

Die Halbleiteroberfläche 2 ist mit bildtragenden Stellen 3 eines vorherigen Druckauftrages versehen, wobei die bildtragenden Stellen hydrophob sind.
Polarisation bedeutet, daß die polarisierten Stellen 5 für den später aufzubringenden Toner 7 empfänglich gemacht werden. Die Polarisationseinrichtung 6 ist mit einer nicht dargestellten Speichereinrichtung für die digital vorliegende Matrix der bildtragenden Stellen verbunden. Die Polarisationseinrichtung 6 ist wie die Löscheinrichtung 4 traversierend oder über die gesamte Breite des Druckformzylinders 1 reichend angeordnet.
