Abstract (en)
[origin: US4833990A] For modifying the printing image on a printing image carrier within a printing press the printing image carrier is in the form of a material with ferroelectric properties. Electrodes with or without heat sources are used to delete and write matter on the printing image carrier by polarizing and depolarizing the respective parts of the printing image carrier or the ferroelectric material. The depolarized material is hydrophobic so that it accepts the printing ink whereas the polarized parts are hydrophilic and accept water.
