UV ink technology extends from theory to practice (I)

UV curable ink and coating have been used in commercial printing since the 1970s, but this technology can be traced back to the early 20th century. In fact, scientists have long known that ultraviolet radiation can promote chemical reactions. For example, the success of silver halide photography depends on its role

unstable unprocessed chemicals or compounds were used in the formulation of early UV ink, rather than the composite processed multifunctional materials we use today. Nevertheless, these early formulations still drove suppliers of printing inks and raw materials to develop better and more comprehensive UV ink solutions

in the past 20 years, especially in the past decade, ink companies have devoted great enthusiasm to this technology. As a result, people can now use high-speed inks on the surface of a variety of substrates. This kind of ink can be maintained outdoors for a long time, and it will not lose its adhesion, color expressiveness or other physical and chemical properties as Volvo rear plate spring project is promoting as planned

this article will examine the development of UV technology, mainly looking at its internal and external impact on the printing industry. For example, it has promoted the formation of ink companies and the application of UV technology in the fields of P-O-P displays, automatic components, packaging and container making, CD and DVD

our planet rotates around the sun, and in turn, the sun brings life to the earth. In fact, this is mainly due to the ability of organisms on earth to convert the radiant energy of the sun into fuel or use this energy to promote biological or chemical reactions. The development of physics is to use things learned from nature to provide solutions to various problems. The same is true of people's use of ultraviolet energy. Scientists have learned how to use ultraviolet radiation to catalyze or promote chemical reactions, and how to use its role to produce raw materials

ultraviolet light energy is also used in the medical field to treat diseases. Ultraviolet light also often helps judges conduct criminal investigations. Because they know that chemical reagents will react or be activated under ultraviolet light, whether in places that cannot be detected by normal lighting equipment or places that are insensitive to them

the reason why ultraviolet light energy is used in so many fields is mainly because of its ability to take effect quickly. Ultraviolet light is so powerful that it takes only a little to make rapid and permanent changes. This feature is also used in the surface coating industry. The surface coating industry was very active in the late 1960s and early 1970s, and is considered to be a substitute for solvent based coating and two-component coating, which are subject to environmental protection laws and regulations

although today's UV coating materials contain ingredients and materials specifically designed for UV curing, this is not the case with early ink formulations. There are very few optional materials, and the stability, toxicity and use proportion of these materials need to be improved. From these perspectives, the progress and development of UV coating is very surprising. Nevertheless, there are other factors that are accelerating the development and acceptance of this technology. Let's now examine these factors

external influence

the history of scientific development is inseparable from good ideas and beliefs, which is a strong thirst for knowledge that is not available in the real world. The road from laboratory to commercial success is very tortuous, and the reasons for failure are various, but it is usually caused by the idea of being eager for success - the world is not ready to accept new ideas

UV curable inks have suffered the same fate, but some progress has increased the chances of success of UV curable inks. As mentioned above, the volatilization of solvents and the improvement of VOC level have aroused the ideas of environmental protectors. The strong need to reduce solvent volatilization prompted scientists to start looking for alternative products for solvent based coating

in addition to the impact on the environment, other commercial factors have also promoted the development of this technology. The most famous is the development of multi-function printing equipment, especially the multi-color online printing machine

the development of UV curable silk printing ink has promoted the new design of online printing machine by printing machine manufacturers. Lithographic printing press, with offset printing ink, plays a dominant role in the field of half tone color printing, and its development speed is that it can be repeatedly melted and reprocessed very fast

silk screen printing ink is limited by printing technology, and its development speed is slow. Silk printing has not been affected by the harsh economic environment, but the lack of high-speed printing capacity has limited its development. The development of existing curing inks is color inks - especially halftone color inks can be printed continuously at a previously unheard of speed

like the development of any major technology, the development of UV pharmaceutical and equipment technology also began with the printer's desire to replace the existing solvent based and oil-based inks with UV technology, and the snowball effect of entering the P-O-P and exhibition image market. This demand has promoted the development of raw materials by the suppliers of monomers and polymers, and the suppliers of traditional components have also joined in, such as the suppliers of pigments, silica gel and fillers. They are also trying to develop some special materials suitable for UV ink to improve the performance of the ink and improve its stability and durability

our joint efforts have promoted the development of raw materials, inks and equipment technology. The formation of ink has become a process of mutual understanding and communication between suppliers and developers, rather than the previous simple linearization

the ultimate winner is the printing press. These initiatives and progress enable them to expand and increase the range of customers. With accurate and high-speed printing ability, silk printing has become a more competitive way than other printing technologies

after some initial mistakes and a series of twists and turns, ink companies that believe in UV ink technology and began to invest in this technology in the early 1980s finally produced inks that meet the commercial requirements of silk printing. Those early formulas often encounter many problems, such as the long-term performance of the ink and the inconsistency of adhesion on the substrate. In addition, health and safety are also problems faced by new monomers and polymers. Nevertheless, in addition to these technical problems, the development and improvement of UV ink technology continue
