UV printing is a printing process of drying and curing inks by ultraviolet light. It is necessary to match inks containing photosensitizers with UV curing lamps. UV inks have covered the fields of offset printing, silk screen, inkjet, pad printing, etc.
Industrial application of UV hardening technology began in the early 1960s when the German wood company used to harden the coating layer on the wood surface. The world's first use of UV lithography was in the United States, and the United Kingdom was successfully used in 1970. Compared with the traditional lithographic printing, it is only a very young new technology, but the development has become a very important printing technology. Generally speaking, UV is not specifically used for lithography, it is a kind of chemical that irradiates chemicals with a UV light source, and the scale "photoinitiator" contained in the chemical is stimulated by the UV light source. The time (less than 1 second) causes the "Polymer" contained in the chemical to produce a glue hardening reaction. "Radiation Curing" (Radiation Curing) is generally called UV Curing. Internationally, "Electronic Beam Curing" (Electronic Beam Curing) belongs to the same category, collectively known as UV / EB Curing. UV hardening can be used in a variety of traditional printing formats, including letterpress, flexible letterpress (Flexo), lithography, screen printing, etc., as long as the use of UV ink, with UV light source to complete the main part. Lithographic UV printing is based on the structure of lithographic printing, using UV inks and UV light sources. Of course, some very important matching conditions need to be reached at the same time. In addition to printing, the use of transparent materials 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 sales of printed materials and enhancing the added value of printing companies' products. There are a lot of success stories about XX printing companies carrying out UV printing business, so profit has doubled. In fact, the widespread application of UV printing technology is at the right time. Today's market is tired of severely homogeneous competition. Many industries are trying to establish their own brands and styles to establish their position in the market, thus jumping out of cheap , Low-end and price wars. The UV printing and UV glazing process realize the extraordinary and breakthrough traditional design through its distinctive sensory effect.
