Abstract

A printing plate is prepared by the process comprising: (a) providing a substrate; and (b) applying by ink jetting to the substrate a fluid composition comprising a cationic polymer and an anionic polymer, in non-aqueous solvent. The ionic polymers interact and adhere to the substrate, so that after drying a durable printing plate is formed, without chemical development. The printing plate of this invention is capable of extended press run length and advantageously avoids the need of chemical development.
