Abstract (en)

[origin: EP0786337A2] The method involves initially electrically charging the entire surface of the printing plate (1). Liquid toner particles (2), individually charged oppositely to the toner or have oppositely aligned dipole or multipole moments, are attracted to the surface. The toner particles are finally fixed or ablated with laser beam, according to the image to be printed. The non-fixed particles are removed or otherwise displaced. The printing plate is completely erased after the printing process has finished, whereby the fixed toner particles are removed. The printing plate is a conductive or dielectric electrically chargeable plate, core or a film of polyester or metal, ceramic or glass rolled on a forme cylinder. The image formed on the plate can be retreated to increase the stability of a layer on its surface.
