Water-based ink is a kind of ink that uses water as a solvent, which has the advantages of environmental protection, non-toxic, odorless, and non-flammable. In the printing industry, water-based inks are becoming more and more widely used, as it not only meets environmental requirements, but also has many other advantages.
First of all, water-based inks have good wetting and permeability. It can penetrate into the substrate in a short time, thus improving the print quality and efficiency. At the same time, due to the low viscosity of water-based inks, it can reduce the wear and tear on the printing machine and extend its service life.
Secondly, water-based inks have excellent drying properties. Under the right temperature and humidity conditions, water-based inks can dry quickly, thus shrinking.
The printing cycle is shortened and the production efficiency is improved.
In addition, water-based inks also have good water resistance and friction resistance. Even in humid environments, prints will not appear smudged or blurred. At the same time, due to the soft texture of water-based ink, the surface of the printed matter is smooth and delicate, and it is not easy to wear.
However, the printing conditions of water-based inks are relatively high. First of all, the printing machine must have certain technical performance and precision to ensure printing quality and efficiency. Secondly, environmental factors such as temperature and humidity need to be strictly controlled during the printing process to ensure the drying and curing of water-based inks.
During the printing process, the following points also need to be noted:
1.The substrate needs to be pre-treated before printing to improve its surface smoothness and ink absorption.
2.During the printing process, it is necessary to maintain a stable printing speed and pressure to ensure the uniformity and consistency of the printed matter.
3.After printing, proper post-processing, such as drying, curing, etc., is required to improve the durability and quality of the printed matter.
In short, water-based ink, as an environmentally friendly, non-toxic and odorless ink, is more and more widely used in the printing industry. In order to give full play to its advantages and improve the quality and efficiency of printed matter, it is necessary to strictly control the printing conditions and technical parameters.
