It is estimated that the sales of the US radiation curing ink and coating market reached US $ 360 million in 2002. Now, the UV curable screen printing inks, offset printing inks, letterpress printing inks and narrow-format flexo printing inks and other ink markets have also achieved such fruitful results.
In recent years, the printing ink industry in the United States, like other industries, has struggled to survive a difficult period. Radiation curing inks are one of the slow-developing fields.
Despite the bright prospects in this area, it cannot escape the strong pressure caused by rising raw material prices. Recently, the severe shortage of acrylic acid has exposed the problems of raw material supply, which has had a certain negative impact on the stability of raw material prices. Last year, the prices of various raw materials rose to varying degrees. This trend of price increases has continued until this year. Therefore, we can foresee that the fluctuation of raw material prices will have a negative impact on ultraviolet / electron beam (UV / EB) products.
The most used areas for ultraviolet (UV) inks are carton and label printing. But at present, carton printing mainly uses offset printing ink, and label printing uses narrow-format flexo printing. The use of UV gravure and wide-width flexo printing is negligible and almost negligible.
Composite printing machines that can use different ultraviolet printing methods are still favored by the industry.
The products printed by the free radical ultraviolet printing system have a certain odor, which makes some printers switch to cationic UV ink and coating when printing flexible packaging that is sensitive to odor. But compared with traditional free radical UV products, the use of cationic UV products is still not enough.

UV curing digital inkjet is a bright star in the field of radiation curing inks and coatings. This emerging technology will continue to develop rapidly. Although there has been a call for reducing the use of volatile organic compounds (VOCs) and reducing energy consumption, printers' interest in UV-curable inkjets has increased. The author believes that this phenomenon mainly has the following reasons:
The curing inkjet has a wider attachment range on the substrate and can be printed on a variety of substrates.
The production efficiency of UV-curable inkjet is higher, and the printing speed is much faster than that of using traditional water-based inkjet or solvent inkjet.
UV-curable inkjet has stable properties and will not block ink nozzles.
Products using UV-curable inkjet printing have better gloss and are less prone to fading.
UV curing inkjet can be used for post-press operations such as embossing.
Advances in technology will continue to promote the rapid development of chemical and UV / EB application equipment. Undoubtedly, today's UV inks have less odor, better viscosity, and stronger color stability. At present, the interior of the high-brightness lamp used for curing ink and the reflector have better thermal control performance. New UV lamps with immediate switching function are also being developed, which may have some advantages of electron beam (EB) curing.
Photosensitive resins and oligomers can absorb ultraviolet energy and promote photopolymerization, thereby greatly reducing the use of photoinitiators and effectively saving printing costs.
Many printers are not interested in new products nowadays unless they taste the sweetness of using new products. Compared with higher production efficiency, the price of UV / EB ink is minimal.
The main benefit of using energy-curable inks and coatings is increased production efficiency. The advantages of fast printing speed, wide printing range, uniform color, and good visual effect are important factors that promote the rapid development of UV / EB ink and coating.
Although UV / EB materials are favored by environmentalists because they can reduce solvent emissions from printing sources, the ultimate use of this material in the food packaging industry will be a major event worthy of industry attention.
UV technology is mature, and printers are still watching, looking forward to the long-awaited sales growth and cost reduction. However, the rising price of raw materials and the slow development of UV / EB ink itself have greatly delayed the arrival of price reduction. On the contrary, prices are likely to continue to rise. The instability of raw material prices will continue to have a profound impact in the near future.
Faux wood Venetian Blinds are constructed of strips that can be rotated in order to be opened, The rotation can be up to 180 degrees and at that position they're closed. This design allows the slats to be rotated. So the light may enter the room. Make room looks more harmony and warmly. Otherwise they can be pulled up so the entire window to be clear. Daylighting adjust can control by yourself until you statisfied. It is Durable, Fireproof, Waterproof, Economic, Heat Resistance. and easy to clean. also easy to installed. It is not only suit for Home use, but also Commercial use. Like Kitchen, Bedroom, Child's Room, Office, and so on. faux wood blinds are warp resistant, have UV ratings as high as 500 and come in colors that would be hard to find in natural wood blinds. Because of their resistance to warping, faux wood window blinds are suitable for areas with extreme temperature swings or high moisture, such as bathrooms and kitchens.
