Problems solved by technology

However, due to the low drying efficiency and high drying energy consumption of water-based inks, and the lack of special printing equipment for water-based inks, the production efficiency is low, resulting in restrictions on the application and promotion of water-based inks, restricting the development of water-based inks

Embodiment

[0021] The present embodiment relates to the gravure printing process of water-based ink, carries out as follows process step:

[0022] a. Equipment printing machine:

[0023] a1. The gravure plate roller adopts laser electric engraving. In order to prevent the water-based ink from eroding the plate roll, the plate roll material with increased chrome plating content is selected. The hardness of the material is limited to 800-900HV. The angle is 130-150 degrees; install the version roller on the mandrel, pay attention to the position of the version roller on the mandrel, make the position of each version roller consistent, put the copper sleeve on the shaft at both ends of the version roller, inject mechanical oil; press the color Install the gravure rollers on the printing machine in sequence, and the alignment lines on each printing plate should be installed on the same side;

[0024] a2. Install embossing rollers, doctor blades, and ink fountains to complete the equipment o...

Abstract

The invention discloses an intaglio printing process of water-based ink. According to the process, laser electric carving intaglio plate rollers are adopted, the net lines of each plate roller are set to range from 80 lines to 110 lines, the needle angle of each plate roller is set to range from 130 degrees to 150 degrees, the layer plate depth in the plate roller printing process is set to range from 24 u to 28 u, and the on-site spot color plate depth is set to range from 28 u to 34 u. Through the adoption of the technical scheme of the process, the intaglio printing process of the water-based ink is obtained; due to the fact that the water-based ink is high in covering rate, good in online rate and good in glossiness, on the premise that the amount of the water-based ink is not changed, the product printing quantity is remarkably increased, the printing quality and the printing ratio are guaranteed, and the production cost is reduced; and intaglio printing equipment does not need to be modified greatly, the limiting factors of the water-based ink applied to intaglio printing are solved, and development of water-based ink printing is promoted.

Description

technical field [0001] The invention relates to the technical field of gravure printing, in particular to the gravure printing process of water-based ink. Background technique [0002] In the field of printing, since printing inks, especially gravure printing inks, use more volatile organic compounds as solvents, they seriously pollute the atmosphere and water resources, which not only directly affect the health and safety of production personnel and users of printed matter, but also The surrounding environment system causes serious pollution and affects people's ecological environment. As people's research on water-based inks found, water-based inks have shown significant advantages in terms of environmental protection, safety, and hygiene. They can not only greatly reduce the emission of volatile organic compounds (VOCs), prevent air pollution, improve the working environment, and reduce fires. It can also improve printing quality, reduce residual solvents in printed matt...
