UV printing is a printing process that uses UV light to dry and cure ink. It requires inks containing photosensitizers to be combined with UV curing lamps. UV inks have covered offset printing, screen printing, inkjet printing and pad printing.
Industrial application UV hardening technology began in the early 1960s when German wood companies used hardening of coatings on wood surfaces. The world's first use of UV lithography was successfully used in the United States in the United Kingdom in 1970. Compared with traditional lithography, it is only a very young new technology, but it has become a very important printing technology. In general, UV is not specifically used for lithography, it is a kind of UV light source illuminating chemicals, and the scale contained in the chemical "Photoinitiator" is stimulated by UV light source, in very short The "polymeric polymer" contained in the chemical produced a gelation hardening reaction in a time (less than 1 second). Radiation Curing, commonly referred to as UV Curing. Internationally, "Electronic Beam Curing" is attributed to the same type, collectively called UV/EB Curing. UV hardening can be used in a variety of traditional printing formats, including letterpress, flexo, lithographic, screen printing, etc. As long as the UV ink is used, the main part is completed with the UV light source. The lithographic UV printing is based on a lithographic architecture, using UV inks and UV light sources. Of course, some very important conditions must be met at the same time. In addition to printing, the use of transparent material prints for UV glazing is also a widely used glazing method on the market.
As early as a few years ago, UV printing began to play an increasingly important role in promoting the sale of printed materials and increasing the added value of products for printing companies. In fact, the widespread use of UV printing technology coincides with the times. Today's market is tired of serious homogenization competition. Many industries are trying to establish their own brand and style to establish their position in the market, thus jumping out of the cheap. The low-end and price wars. UV printing and UV glazing are the result of extraordinary, breakthrough designs through its distinctive sensory effects.
