Abstract
A method for reversible imaging of a printing form is provided included feeding a coated transfer film between a printing form and an image information transfer unit having a transfer head. A surface of the printing form is then imaged using image data oriented activation to transfer the transfer film coating in the form of image spots to the printing form. The transfer film is removed from between the printing form and the image information transfer unit. The transferred image spots are fixed on the printing form by re-imaging or fixing the image spots using image data oriented activation. Remaining image information from the printing form is removed or erased once the printing operation is complete so that the printing form is capable of being used in a subsequent printing operation. A device for performing the method is also provided. Optionally, a single laser beam or a plurality of laser beams may be used in the device.
