Abstract

The invention relates to an ink-jet printing plate making method for a substrate used for intaglio printing. The method comprises the following steps that (1) the surface of the substrate is uniformly coated with an imaging layer composed of polymer precursors, and the polymer precursors are pre-cured through the inducing function triggered by heating or light, so that the imaging layer is in a sticky and elastic state; (2) sacrificed ink is printed on the imaging layer through the ink-jet printing technique, and the polymer precursors are further cured completely through the inducing function triggered by heating or light; (3) after the sacrificed ink is removed through cleaning, concave structures capable of absorbing ink are left on the imaging layer, and thus the substrate used for intaglio printing is obtained; and (4) after the printing task is finished, the surface imaging layer is removed, and therefore the substrate can be utilized repeatedly. Compared with the prior art, the method is simple in technique, low in cost and capable of achieving large-area plate making; all materials are non-poisonous and harmless, and health protection and environment friendliness are achieved; and the substrate can be utilized repeatedly, and the materials are saved.
