ABSTRACT:
A printing head suitable for imaging a ferroelectric printing form is sealed relative to the printing form by a spring-elastic seal. In the discharge chamber of the printing head, at a low pressure, preferably less than 10 hPa, and especially in the presence of a gas with high ionization probability, a discharge plasma is created, from which charge carriers emerge onto the printing form as the result of activation between electrodes, with simultaneous focussing by the application of electric and/or magnetic fields between plates.
