Pad printing is a very simple process. It uses steel (or copper or thermoplastic) intaglio and uses a curved pad made of silicone rubber. The ink on the plate is dipped on the surface of the pad and then pressed on the surface of the desired object to print words and patterns.

It can print words, graphics and images on irregular surfaces and is now becoming an important special printing. For example, text and patterns on the surface of mobile phones are printed in this way, and the surface printing of computer keyboards, instruments, instruments and many other electronic products are completed by pad printing.

In recent years, screen printing has been paid attention to, primarily because of its printing advantages in paper. For example, the use of screen printing to complete the uv local glazing of paper, special UV ink such as coral ink, ice ink, zou grain ink printing than offset, flexographic printing better effect. Pad printing machine was introduced to China in the 1980s. Because it can be printed on products with small area and concave and convex surface, it has very obvious advantages to make up for the deficiency of screen printing. Therefore, it has developed rapidly in recent years. With the further opening of China's market, a large number of electronic, plastic, gifts, toys and other traditional industries based foreign enterprises have entered our country, with pad printing and screen printing technology based decoration has been extraordinary development. According to incomplete statistics, pad printing and screen printing technology in the above industries have reached 27%, 64%, 51% and 66% respectively.

The combination of pad printing processing technology and screen printing technology has opened up a new situation of printing market. From the traditional labor intensive, step forward to technology intensive gradually. This is a trend to adapt to the development of the world. At present, pad printing machine pad printing process is constantly improving and improving. Suzhou silk screen printing ink

Ink is very important for pad printing technology. Now, the emergence of closed ink, can be said to be pad printing machine and pad printing technology a new progress. First of all, it is energy saving and environmentally friendly, because it saves the amount of ink, and at the same time workers enjoy a more sanitary and comfortable environment. Secondly, it also saves time and effort, because of the long-term stable viscosity of the ink, so that it avoids the trouble of cleaning the ink cartridge and scraping knife after printing. In addition, in the mass production operation, the use of closed ink is more suitable. It has taken into account more factors in the use of staff, making the production efficiency and quality have been further improved.

At present pad printing technology is also in the field of renewal. In order to put into production more effectively, pad printing technology is gradually completed online production, the pad printing machine and the whole production and operation organically combined to form a complete and unified link. At present, pad printing technology is gradually moving towards the automation of printing, high precision system not only through the quality of printing precision, but also to meet the needs of mass production. In addition, pad printing printing technology is gradually and production environment, product consumption and maintenance to form a complete part.
