Analysis of the current situation of the U.S. UV ink market

in the U.S. ink market, the sales of energy curing ink and varnish have increased greatly, mainly UV curing ink used in printing, offset printing, embossing and web narrow flexible printing. In recent years, the American ink industry as a whole has been in a downturn, with the exception of a few products. It still maintains a trend of growth against the trend, and energy division ink is one of them

although energy curing inks have a bright future, this market is still under the pressure of rising raw material prices. Recently, the shortage of acrylic resin in the market has caused the shortage of raw materials in the ink industry and led to the rise of ink prices. Since 2004, the prices of many raw materials have increased to varying degrees, and this trend may continue, so it can be predicted that the fluctuation of raw material prices will eventually have a negative impact on UV ink and Hotan ink

folding cartons and labels are the two main application areas of UV ink. Among them, the folding carton printing mainly adopts the sheet fed offset printing method, and the label printing adopts the typical web paper narrow width, which not only needs to fundamentally transform the flexographic printing method from the plastic granulator process. In gravure printing, UV ink is rarely used in the market, which is almost negligible. Similarly, UV ink is rarely used in wide web flexographic printing. At present, the combined printing machine integrating various UV printing methods is more and more popular with users. Because some free radical UV inks have odor problems, some printing enterprises begin to use cationic UV inks and varnish for printing and glazing of those soft packaging products that are sensitive to odor. However, compared with the traditional free radical UV ink, the application range of cationic UV ink is still very narrow. At present, UV digital inkjet printing is a new field in the application field of energy curing ink and varnish, and it is a very promising field. 1. The field of adopting exchange servo electromechanical and exchange servo speed regulation system to control the experimental process has maintained a rapid growth momentum. The factors that promote the rapid growth of UV digital inkjet printing inks are not only VOC free and reduced energy consumption, but also the following main reasons

(1) UV digital ink-jet printing ink has a wider range of applications. It can be printed on a variety of substrates

(2) compared with traditional water-based or solvent based inkjet printing inks, UV digital inkjet printing inks can print faster and significantly improve production efficiency

(3) UV digital inkjet printing ink has good stability and will not block the inkjet head

(4uv digital ink-jet printing ink has strong resistance, such as friction resistance, light resistance, etc.

(5) UV digital ink-jet printing products can also be processed after wiring, such as embossing, etc. The progress of technology also promotes the further development of chemical industry and UV/EB application equipment. For example, UV inks with lower odor, better viscosity, more stable hue have been introduced in the market at present: UV lamps with higher intensity have been introduced, and the cooling effect of UV curing system is better: new UV lamps with instantaneous switching function are also being developed. These new functions may make UV curing have some new characteristics close to field curing: when using light, 1 be careful to sensitive resins and oligomers to absorb UV energy, And catalyze the photopolymerization reaction, which can reduce the amount of external photoinitiator

nowadays, many printing enterprises are not very interested in new products that cannot bring them great benefits. Although the current price of UV/EB ink is relatively expensive, the production efficiency has reached a new level

improving production efficiency is the main advantage of energy curing inks and varnishes because it is currently impossible to predict the strength and performance of materials and components under variable loads by theoretical methods. Faster printing speed. Better consistency and visual effect of a wider range of substrates are also factors that promote the increasing consumption of UV/EB inks and varnishes

in addition, although UV/EB ink does not contain VOC, which is conducive to environmental protection, it is still a big problem to use it in the food packaging industry. Now, UV technology is approaching maturity. The amount of UV ink has also increased greatly. Therefore, printing enterprises are looking forward to the decline of UV ink prices. However, the rise in raw material prices has become an important obstacle, making it difficult for printing enterprises to realize this wish. On the contrary, the price of UV ink may continue to rise. The instability of raw material prices will still be an important factor affecting the price of UV ink
