Abstract
Abstract A method and apparatus for direct production of photopolymeric printing plates. The method comprises forming a positive and/or negative image on a substrate by ink-jet printing with a photopolymeric ink composition, optionally preheated. The apparatus for carrying out the method of the invention comprises a rotatable drum adapted for retaining on its inner or outer surface the substrate to be printed; a carriage, displaceable axially in respect of the drum; a container for a photopolymeric ink composition; at least one nozzle communicating with the carriage for ejecting the photopolymeric ink composition; and a UV source located so as to expose the printed surface of the substrate to UV radiation.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
55 words
A method for the production of photopolymeric relief-type printing plates comprising: forming a positive or a negative image on a substrate by ink-jet printing with a photopolymeric ink composition, optionally preheated to a temperature of about 30°-260° C.; and subjecting the resulting printed substrate to UV radiation, thereby curing said ink composition forming said image.
Claim 2
Independent Claim
55 words
A method for the production of photopolymeric relief-type printing plates comprising: forming a positive or a negative image on a substrate by ink-jet printing with a photopolymeric ink composition, optionally preheated to a temperature of about 30°-260° C.; and subjecting the resulting printed substrate to UV radiation, thereby curing said ink composition forming said image.
Claim 3
Dependent Claim
22 words
A method according to claim 1, wherein the photopolymeric ink composition comprises from about 0.5 to about 20% of a ferromagnetic powder.
Claim 4
Dependent Claim
22 words
A method according to claim 1, wherein the photopolymeric ink composition comprises from about 0.1 to about 10% of a conductive additive.
