Flexographic plate CTP (computer to plate) direct printing method and equipment based on 3D rapid forming printing principle

Abstract

The invention discloses a flexographic plate CTP (computer to plate) direct printing method and equipment based on a 3D rapid forming printing principle and belongs to the technical field of printing flexographic plate manufacture. The equipment comprises a computer, a 3D rapid forming printer and one of photocuring equipment and heat drying equipment. The 3D rapid forming printer is utilized to spray a solidifiable forming material on the base surface of a flexographic plate so as to form a relieve image, the relieve image is subjected to light curing or thermocuring on-line drying so that the printing information is stabilized on the base surface of the flexographic plate, and then the printer can be used for printing; and the base of the flexographic plate is an organic polymer plate or an organic polymer-organic polymer compound plate. The method omits the middle process such as exposure and development, the plate manufacturing speed is greatly accelerated, the printing quality is improved, the printing cost is reduced, the flow is greatly shortened, the flexography environment friendliness is realized, and the application area is further expanded.

Description

technical field

[0001] The invention belongs to the technical field of printing flexible plate making, and designs a CTP computer direct plate making flexible plate technology method and related equipment utilizing the principle of 3D printing. Background technique

[0002] Flexographic printing (flexographic process) is to make a convex printing plate of the desired image mirror image on polyester or other polymer materials, the ink is transferred to the printing plate, and the surface of the printing plate is in contact with the substrate during rotation, so that A printing method of transferring pictures and texts. Compared with several other printing methods, flexographic printing has unique flexibility, economy, and is beneficial to the protection of the environment, and meets the hygienic standards of food packaging printing. At present, flexographic printing can fully meet the requirements of tobacco packaging, pharmaceutical packaging, food packaging, label printing...
