UV printing include offset printing, silk screen, inkjet, pad printing, and other fields into a valley _ printing equipment printing

Takeaway: UV printing is a UV drying, curing ink through a printing process, need to match the ink and UV curing lamp containing photosensitizer, UV ink has offset printing, silk screen, inkjet, pad printing, etc. UV printing is a UV drying, a kind of curing ink printing process, need to match the ink and UV curing lamp containing photosensitizer, UV ink has offset printing, silk screen, inkjet, pad printing, etc. Industrial application of UV hardening technology began in the early 1960 s, Germany wood industry company in wood coating layer on the surface of the hardened. Global use UV lithography is in the United States, Britain and successfully use in 1970. Compared with traditional lithography, only is extremely young new technology, but the development has become a very important printing technology. In general, UV is not applied in printing, it is a kind of chemicals with UV light radiation, and the scale of chemical compositions containing light starting agent ( Photoinitiator） By the stimulation of the UV light source, in a very short period of time ( Shorter than 1 second) Let the chemicals contained in the polymerization of monomers, Polymer） Produce glue hardening reaction. Radiation hardening technology ( RadiationCuring) (commonly referred to as UV sclerosis, UVCuring） 。 And the electron beam hardening technology (international ElectronicBeamCuring) Due to the similar, called UV/EBCuring. UV hardening can be used in all kinds of traditional printing formats, including letterpress, elastic letterpress ( Flexo） , such as screen printing, lithography, as long as the UV ink, cooperate with the UV light source to complete the main part. Planographic printing is that UV lithography, the architecture of the use of UV ink, cooperate with the UV light source, and of course some very important matching conditions at the same time reach is required. In addition to printing, print use transparent material UV glazing is also widely used way of polishing on the market. sohu
