Embodiment 1

[0029] Prepare a prepolymer mixture with a molar ratio of dimethylsiloxane monomer and initiator ethylene of 5:1, mix well and vacuumize to remove air bubbles for later use. choose as figure 2 and image 3 The rough aluminum plate shown is the plate base, on which the prepolymer mixture is coated with a coating machine, and the coating thickness is controlled to be 5 microns. The plate base coated with the prepolymer is preheated and cured in an environment of 90° C. for 5 minutes, so that the polymerization of the prepolymer on the surface of the plate base becomes a viscoelastic state. A 5wt% polyacrylic acid aqueous solution was prepared as a sacrificial ink, and dot matrix was printed on the surface of the plate base. After the printing is completed, place the plate base in a 90°C environment and heat it for half an hour to completely cure the plate base. After the base was taken out and cooled to room temperature, the base was rinsed with a large amount of water to re...

Embodiment 2

[0031] Prepare a prepolymer mixture with a molar ratio of dimethylsiloxane monomer and initiator propylene of 10:1, mix well and vacuumize to remove air bubbles for later use. choose as figure 2 and image 3 The rough aluminum shown is the plate base, on which the prepolymer mixture is coated with a coating machine, and the coating thickness is controlled to be 1000 microns. The plate base coated with the prepolymer is placed in an environment of 50° C. for preheating and curing for 30 minutes, so that the polymerization of the prepolymer on the surface of the plate base becomes a viscoelastic state. A 30wt% aqueous solution of polyacrylic acid was prepared as a sacrificial ink, and dot matrix was printed on the surface of the plate base. After the printing is completed, place the plate base in a 70°C environment and heat it for 1 hour to completely cure the plate base. After the base was taken out and cooled to room temperature, the base was rinsed with a large amount of ...

Embodiment 3

[0033] Prepare a prepolymer mixture solution with a molar ratio of dimethylsiloxane monomer and initiator 1-dodecene of 50:1, mix evenly and vacuumize to remove air bubbles for later use. choose as figure 2 and image 3 The rough aluminum shown is the plate base, on which the prepolymer mixture is coated with a coating machine, and the coating thickness is controlled to be 10 microns. The plate base coated with the prepolymer is preheated and cured in an environment of 90° C. for 5 minutes, so that the polymerization of the prepolymer on the surface of the plate base becomes a viscoelastic state. Prepare 5% polyacrylic acid aqueous solution as a sacrificial ink, and print parallel lines on the surface of the above-mentioned plate base. After the printing is completed, place the plate base in a 90°C environment and heat it for half an hour to completely cure the plate base. After the substrate was taken out and cooled to room temperature, the substrate was rinsed with a lar...

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.

Description

technical field [0001] The invention belongs to the technical field of gravure printing plate making, and in particular relates to an inkjet printing plate making method of a substrate for gravure printing. Background technique [0002] Gravure printing is a plate-making technique that absorbs ink through the recessed structure on the printing plate and imprints the ink directly onto the substrate. As one of the four major printing methods, gravure printing is widely used in the printing of valuable securities such as magazines, product catalogs, packaging printing, banknotes and stamps. Compared with other printing technologies, the ink layer of printed products printed by gravure printing technology is thick, and the color is bright and saturated. For the printing of securities, etc., it also reflects the advantage of gravure printing with anti-counterfeiting function. [0003] At present, the plate-making methods of gravure printing can be divided into three categories:...
