Multi-process combined printing method based on flexible plate equipment platform

Abstract

The invention relates to a multi-process combined printing method based on a flexible plate equipment platform, and belongs to the technical field of printing. The method utilizes a flexible plate printing mode as a process platform, combines gravure equipment, silk-screen equipment, bronzing equipment and punch die cutting equipment with flexible plate printing together to form a combined printing mode and produces a finished production once. The method integrates the gravure equipment, the silk-screen equipment, the bronzing equipment and the punch die cutting equipment into the platform, concentrates gravure, silk-screen, bronzing and punch die cutting and other working procedures together, separately drives a printing plate roller and a printing bearing roller of each color set through an independent servo motor, can make the overprinting precision reach over + / -0.05 mm and the precision of plate hop seam reach within + / -0.25 mm, realizes the function of the online shifting of the plate hop seam of a flexible plate and completes the online automatic flexible plate printing.

Description

technical field [0001] The invention relates to a flexographic printing technology in the printing industry. Background technique [0002] Various printing technologies exist independently as unique printing methods of printing. Different printing methods need to be completed by different printing equipment. Generally, printing starts from flexo printing, and then transfers to gravure printing equipment, silk screen printing equipment, bronzing equipment, etc. Equipment and concave-convex die-cutting equipment are carried out separately; in terms of equipment investment, staffing, material consumption, delivery time, etc., the customer's requirements cannot be met, and the efficiency is quite low; moreover, the paper after printing is seriously deformed, and the overprinting between the front and back processes The precision cannot meet the requirements of product quality. At the same time, paper, as a special process, must be completed by the paper manufacturer. There has n...

[0002] Various printing technologies exist independently as unique printing methods of printing. Different printing methods need to be completed by different printing equipment. Generally, printing starts from flexo printing, and then transfers to gravure printing equipment, silk screen printing equipment, bronzing equipment, etc. Equipment and concave-convex die-cutting equipment are carried out separately; in terms of equipment investment, staffing, material consumption, delivery time, etc., the customer's requirements cannot be met, and the efficiency is quite low; moreover, the paper after printing is seriously deformed, and the overprinting between the front and back processes The precision cannot meet the requirements of product quality. At the same time, paper, as a special process, must be completed by the paper manufacturer. There has never been an online transfer lamination on the printing equipment before printing paper directly.

The overprinting of printing equipment is manual operation, and each printing plate roller needs to be manually rotated, and the precision is difficult to control. Basically, a color group needs to be rotated 2 to 3 times, and a group of monochrome groups need to be adjusted for registration, and the consumption more time and materials
