Problems solved by technology

[0004] Therefore, it is imminent to choose a printing technology that is environmentally friendly, pollution-free, zero-emission, and harmless to the human body. At present, the environmentally friendly water-based ink printing that exists in the domestic and foreign markets is mostly used in paper printing, especially for plastic film printing. Shrinkage occurs after heating Deformed plastic films, such as PVC, PE, PP and other materials have not yet been realized. The existing technical problems mainly lie in: (1) water-based ink is not easy to dry; pattern effect

Embodiment 1

[0021] A kind of high-efficiency gravure printing process based on plastic film proposed by the present invention comprises the following steps:

[0022] S1. Preparation before printing: Install the plastic film to be printed into the gravure printing machine, check whether there is any jamming in each part of the machine, and inject lubricating oil into the lubricating part;

[0023] S2. The plastic film to be printed passes through multiple printing units in sequence to print in different colors;

[0024] S3. Plate loading: install the printing plate cylinders in each color group according to the printing color sequence;

[0025] S4. Adjust the squeegee on the rule: After the pre-printing preparations are completed, carefully calibrate the printing plate, check the paper feeding, feeding, receiving, and push-pull rules, and make appropriate adjustments to correct the pressure. The hard knife linings are overlapped and placed in the middle of the upper and lower clamping pla...

Abstract

The invention discloses an efficient gravure printing process based on a plastic film. The process includes the steps that S1, preparation before printing is conducted: the plastic film to be printed is mounted into a gravure printing machine, whether each part of the machine is jammed or not is detected, and lubricating oil is injected into a lubricating part; S2, the to-be-printed plastic film sequentially passes through a plurality of printing units to be printed in different colors; S3, plate mounting is conducted: plate cylinders are mounted in all color groups according to a printing color sequence; and S4, a doctor blade on a gauge is adjusted: after preparatory work before printing is completed, a printing plate is calibrated carefully, and the conditions of paper feeding, paper conveying, paper collecting and gauge pushing and pulling are checked. According to the plastic film printed through the efficient gravure printing process based on the plastic film, ink is not separated, ink color is uniform, printing marks are not pasty and fluffed, spots, scratches, pigment precipitation and dirt sticking are avoided, the printing effect is good, and the printing efficiency is high.

Description

technical field [0001] The invention relates to the technical field of plastic films, in particular to a high-efficiency gravure printing process based on plastic films. Background technique [0002] Plastic packaging bag is a kind of packaging bag that uses plastic as raw material to produce various supplies in daily life, and is widely used in daily life and industrial production. In the production process of plastic packaging bags, in order to improve the degree of identification and aesthetics, plastic packaging bags are usually printed to varying degrees. [0003] Gravure printing is to apply ink to all parts of the layout first, then use a scraper to scrape off the ink along the blank part, and then directly transfer the ink in the concave cells to the surface of the carrier through pressure. At present, the process of gravure printing PVC film at home and abroad mainly uses solvent ink, which is characterized by fast printing speed, bright color and simple equipment;...
