Ink
Pad printing inks are still mainly based on solvent-based inks. Pad printing inks have been replaced by screen printing inks. The effect is also very good. Most ink manufacturers currently use pad printing inks and screen printing inks as a series to produce inks. . However, there are also many problems with screen printing inks used in pad printing processes. MARABU pioneered the development of pad printing inks. In contrast, special pad printing inks have faster and more stable drying and better thixotropy. The ink layer of the pad printing process is relatively thin. In order to obtain a more eye-catching handwriting, the purity of the pigment in the ink is higher and the fineness is finer, which is a difficulty in manufacturing the pad printing ink. At present, printing ink In addition MARABU company has a special series, Germany's DUJO's printing ink also began to occupy a certain market. In addition, there are only a few special printing inks, and British COATES inks, which are well-known for the production of screen printing inks, also have a small market share as an alternative to medium and low-grade products.
The printing ink market is vast and profitable, attracting the research and development of many domestic enterprises. The domestic ink production has recently been developing very rapidly. The outstanding products include Zhongshan Zhongyi Ink Co., Ltd., Hangzhou Kewang Ink Co., Ltd., and Shenzhen Miramar Ink Co., Ltd. Ltd.
UV inks have long been common in the field of screen printing. Now, one final bastion is that UV pad printing inks cannot be replaced with screen printing inks like solvent inks. UV screen printing ink production process is much simpler, as long as the ink permeability is good, the printing effect is very easy to guarantee, and UV pad printing ink requires the transfer of the printing head to the ink acrylic monomer monomer transferability Well, generally speaking, the pad printing head is made of silicone rubber. The affinity of the silicone rubber and the acrylic monomer monomer is poor, and the transfer efficiency will be affected. On the other hand, the solvent ink must be added with the necessary filler to improve. The trimming and trimming of the imprinting, however, can not add too much of such fillers in the UV pad printing ink. In addition to affecting the curing efficiency, the transparency of the ink will be difficult to guarantee: in the development of UV pad printing ink, to ensure the color of the pigment High concentration but good transparency and good transferability are difficult points. Now these problems have been overcome by Ni. MARABU, a professional manufacturer of pad printing inks, has fully brought their TPC series of UV printing inks to market.
The successful development of UV printing inks has solved some problems that have plagued people. For a long time, the glossiness and wear resistance of computer keyboards have not met the requirements of customers. Using UV inks has become the goal pursued by many manufacturers. However, printing UV inks with screen printing methods has a lot of troubles. The method of pad printing completes the transfer of UV ink and it is easy to meet the requirements of customers. The printing process features pressure from just above the substrate to complete the printing, so the printing process can easily prevent the product from shaking.
Oil type pad printing machine
China has developed rapidly in recent years. Western countries’ advantages in traditional industries have gradually been replaced by China. In order to protect the development of domestic industries, some countries in Europe and the United States have formulated a very strict market access system to restrict Chinese products from entering the EU market. Products manufactured by companies exported to the European Union conform to ISO14001 environmental standards. Objectively speaking, the technical barriers between European and American countries are very unfavorable to Chinese companies. However, in the long run, the pressure imposed by these institutions on Chinese companies may force us to adopt new technologies to improve our country. The technical and safety level of the product. Performance in the field of pad printing technology, the use of more environmentally friendly technology must attract the attention of Chinese companies.
Solvent-based solvents that evaporate into the air are trapped in the human respiratory system and most of them are harmful to the human body. This has been met with widespread resistance from Western societies that protect human life. European and American countries have formulated strict regulations. Regulations to control the use of solvent-based inks. Germany first produced a pad printer that controlled the volatilization of solvents by cutting off the solvent volatilization. This was the oil pad printer. The main difference between it and the traditional open printing machine is the difference in ink supply.
The ink supply part of the oil pad printer uses ink and solvent cartridges that are refastened on the pad plate to continuously supply ink to the plate. Since the solvent is volatilized, the viscosity of the ink during use is controlled. And the change of the drying speed tends to be stable, which is more conducive to obtaining uniform and consistent printing quality. The stability of the open car is the most commendable advantage of the ink pad printing machine. The effective reduction of solvent evaporation also improves the operating environment of operating personnel. It is worth pointing out that the manufacturing level of the ink pad printer reflects the level of manufacturing of a company. At present, there are only a handful of companies in the country that are making quality ink pad printers.
Application of pad printing technology
The advantages of the oil-pad printing machine have won the favor of companies that are applying for or have obtained ISO14000 environmental management certification. However, we cannot but admit that the oil-pad printing machine has not absolutely eliminated environmental damage. A part of the solvent enclosed in the oil crucible reaches a dynamic equilibrium inside the oil crucible, and the other part is transferred to the surface of the product together with the pigment and the resin. The solvent finally needs to evaporate into the air. The main function of the oil crucible is to put the solvent in the ink. Volatilization becomes effective volatilization. Whether it is the ink loading process or the cleaning process, we can't completely rule out the volatilization of the solvent. Therefore, the ink pad printer will face the challenge of UV pad printing sooner or later. UV technology is an environmental technology that became popular in the 1980s. It uses photosensitive inks based on acrylic resin as a substitute for long-standing solvent inks. In the field of offset printing, gravure printing, flexo printing, and screen printing, UV technology is gaining popularity. In contrast, UV printing technology is late.
The reason why UV technology is progressing slowly is because the development of UV inks faces some difficulties, as mentioned above. Any new technology will face various difficulties, but there is no difficulty to stop the development of UV printing technology. As more companies pay attention to UV printing technology, the popularity of UV technology in the printing field is sooner or later.
Because of the successful development of UV inks, the major obstacles to UV technology have been removed. Other related technologies can be put into production with only minor modifications. For example, the products involved in pad printing are relatively small, and it is easy to implement a miniaturized curing device. The pre-processing, printing system and curing device integrated pad printing machine should be on the agenda. I believe that in recent years will be the critical period for the further perfection of UV printing technology.
