Single-sided and double-sided dual-purpose connecting line face-to-face printing offset press and printing method thereof

Abstract

The invention discloses a single-sided and double-sided dual-purpose connecting line face-to-face printing offset press. The single-sided and double-sided dual-purpose connecting line face-to-face printing offset press comprises a paper control mechanism, a blanket cylinder, a plate cylinder, an impression / offset cylinder and an ink supply system. The blanket cylinder and the plate cylinder are respectively provided with a printing blanket and a printing plate which press each other correspondingly, the printing blanket is of a single-blanket two-unit structure, the printing plate is of a single-plate two-unit structure, the impression / offset cylinder and the printing blanket of the blanket cylinder correspondingly press each other, and the ink supply system is used for supplying ink to the plate cylinder. According to the single-sided and double-sided dual-purpose connecting line face-to-face printing offset press, when the single-sided offset printing and two-sided offset printing are performed simultaneously, a single-piece continuous paper feeding mode is utilized, and any adjustment to the device is not needed; when a face-to-face printing function is utilized, front images and texts and back images and texts are manufactured on the same printing plate, so that factors affecting precise face-to-face printing in an engineered mass production can be reduced to the minimum, front-back printing errors can be less than 0.1 mm, transmittance and color changing can be guaranteed, and the stable operation of height-class printing anti-counterfeiting technologies of datumized watermark, two-sided connecting lines and front-back connecting lines and the like in the mass production can be achieved.

Description

[0001] technical field [0002] The invention belongs to the technical field of printing, and in particular relates to a single- and double-sided dual-purpose six-color wiring offset printing machine and a printing method thereof. Background technique [0003] Double-sided printing counter-printing is a difficult printing technology, which is difficult to counterfeit and easy to be recognized by the public. Therefore, it is widely used in banknotes, valuable tickets, anti-counterfeiting documents, anti-counterfeiting packaging and other printed materials that have high requirements for products. [0004] Known double-sided offset printing technologies include flip-type double-sided offset printing machines, double-layer alternate double-sided offset printing machines, split-layer double-sided offset printing machines, horizontal B-B type double-sided offset printing machines, etc. The color is the printing unit, and the printing unit structure is used for multiple overprintin...

AI Technical Summary

Problems solved by technology

Most of the known offset printing double-sided printing machines are unit structures, which cannot be used as anti-counterfeiting double-sided printing machines, let alone wiring printing

The current offset printing machine in the banknote printing industry is a satellite structure, which can perform front and back printing, but only one side can be connected, and the other side can be overprinted.
