The combination of UV ink and screen printing chocolate boxes is worth looking forward to in the future

Screen printing, one of the four modern printing methods, is being recognized by more and more audiences due to its advantages of large batches, low prices, bright colors, long shelf life and fast delivery, and is widely used in the printing industry. application. UV ink is an environmentally friendly ink that has developed rapidly in recent years. It is favored by people in the printing industry for its instant curing, drying, no volatile solvents, and simple and convenient application.

Screen printing applications: a wide range of UV inks with great potential

What happens when UV ink meets screen printing? In fact, UV ink has already been widely used in screen printing, and the printing materials are more diverse, such as circuit boards, textiles, paper, synthetic paper, wood products, plastics, coated metals, glass, ceramics, etc. are included.

Chocolate boxes screen printing has thick ink layer, bright color, simple process, low investment and quick effect, so it has won many awards in light industry, electronics, machinery, automobile, textile, chemical industry, commerce, art, advertising, decoration, packaging and many other industries. Wide range of applications, especially in the fields of decorations, beautifying people's lives, commercial advertising and printed circuits in the electronic industry, have played an irreplaceable role in other printing methods. In the modern printing industry, it cannot be called a complete printing enterprise without screen printing, so it is not too much to evaluate. In addition, it is believed that with the rise of the consumer market, the public's demand for screen printing products will definitely increase, the screen printing industry will expand, and technological upgrading is imperative.

However, with the continuous development of screen printing technology, screen printing equipment will also develop from manual and single-color to fully automatic and multi-color automation, and the quality and grade of printing will be significantly improved. It puts forward higher requirements for screen printing ink. In the future, more environmental protection and more technical content will definitely become the double standard of screen printing and screen printing UV ink.

Features determine the application of UV ink to screen printing

Some people say that it is inevitable for UV ink to be used in screen printing. The reason mainly depends on the characteristics of UV ink itself. So what are the characteristics of screen printing UV ink?

(1) The curing speed is fast, the UV equipment is small in size, and the production efficiency is high.

Chocolate boxes UV ink is very suitable for multi-color and fully automatic flow operations, while the drying of solvent-based inks in the past requires a long drying line, and even some single-color prints require a drying device of about 10m. After screen printing uses UV ink, only one UV light source is needed to solve the problem, which saves the cost of purchasing equipment, saves space, and greatly improves production efficiency.

(2) The ink will not block the screen, the concentration is stable, and it is suitable for high-quality printing.

Some people say that 90% of the problems in the screen printing process are related to solvents. Solvents are an important part of screen printing inks. However, due to different regions, temperatures and humidity, the performance of inks is also very different. Therefore, it does not contain volatile substances, the viscosity of the ink changes little, and the UV ink is easy to operate, which solves these problems and greatly improves the printing quality. In addition, due to the fast curing speed of the ink, the residence time of the printed matter during the drying process is shortened, and the possibility of being polluted by dust is reduced.

(3) It does not contain volatile solvents and has no negative impact on the human body and the environment.

At present, the commonly used inks for screen printing, in terms of output and variety, volatile drying solvent inks are the mainstream. Because of its slow drying time, 60% of the solvent will be volatilized during the drying process, so it will cause great pollution to the environment. Seeking UV ink with less pollution, fast drying and less energy consumption has become the common goal of people in the printing industry.

(4) The ink layer is thick, the substrate is wide, and the operation is simple and flexible.

In general solvent ink, the solid content of ink is about 40%, while the solid content of UV ink after curing is close to 100%, which is 2 to 5 times that of general ink. It is better to use thick film screen printing UV ink, so it is more suitable for screen printing.

(5) Good wear resistance, solvent resistance, weather resistance and other properties.

The chemical substances in the UV ink form a polymer three-dimensional network polymer through the cross-linking reaction. The surface of the ink has strong chemical resistance and friction resistance, which can reduce the loss caused by the harsh environment during the transportation of the printed matter and prolong certain periods of time. Time for the print to be displayed outdoors.
