Heavy ion micro technology Heavy Ion porous security logo security printing field is developed on the basis of two high-tech research results, a nuclear heavy ion microporous membrane technology, the other is a heavy ion lithography. Its manufacturing process comprises three steps: Firstly, heavy ion accelerator or a reactor neutron-induced fission fragments of uranium as a "shell" bombardment of plastic film, causing ionization damage plastic film surface and interior, nuclear track base film; and Copy the security logo master pattern into transition film version, a lithographic printing base film forming a mask; and finally by a chemical etching process, the base film produced by the heavy ion microporous composition, the same pattern of the original master. Heavy ion microporous identified using non-direct radiation imaging method of manufacturing, it is the heavy ion lithography development and application in the field of security. Heavy ion porous hole density identified up to several million per cubic centimeter heavy ion microporous. The pore diameter is small, in the micron or submicron range color sticker printing, only one hundredth the diameter of a human hair is about, invisible. But by the heavy ion microporous diffraction and refraction of light, security patterns by the large number of micropores community composition appear white color stickers printing custom Dongguan visually, it is easy to identify with the naked eye, become a popular macro basis to identify the authenticity of goods , and heavy ion microporous microstructure and properties you can use an optical microscope. Heavy Ion porous security logo has a "microscopic located close macro displays" characteristics, to achieve the security objectives of the Expert identification and public recognition combination. On the one hand, the heavy ion micro microscopic science has very strict parameters, such as pore density, pore diameter, pore overlapping chances like. These parameters are controlled by irradiation and etching processes, forming a strict code signal, permanently stored in the internal knowledge, to become experts in the identification and legal appraisal of scientific evidence. Development Status flexo 1, the current development of flexo flexographic printing dating back to 1853 to get the United States Hopkins rubber plates patent, and China in the early 1970s, before the introduction of the flexographic printing process, and after several technical innovation, after years of practice, only in China's packaging printing industry to establish its own position. Flexo market currently accounts for the entire printing market, about 7%. From the beginning of the 1990s, China's flexo showing a trend of rapid development in recent years is the entire printing industry in a strong position, has become one of the most developed market and development potential of printing. At present, China can meet the middle and low cigarette flexo, pharmaceutical packaging, food packaging, labels, printed stickers printed packaging requirements, cartons, paper lunch boxes, etc. are most used currently flexo. According to statistics, the domestic cigarette packaging printing flexo press for 30 per cent; for 15% of label printing; stickers printed for 35%. Cutlery, cups, drinks, etc. 80% of coated paper printing are also using the flexographic printing. Currently associated with domestic market is the largest flexo corrugated boxes, about 70 percent annually flexible plate sales in the carton industry, Nestle, Johnson & Johnson, secret, aims to Durkee and other brand-name companies have adopted the flexo packaging. Transport Packaging ordinary cardboard boxes all use flexo. Today flexographic printing with quality comparable to offset printing, so some manufacturers have been producing cartons folding cartons with web flexographic presses to change the folding carton sales market becomes more and more difficult situation. Today, the domestic packaging and printing enterprise applications from abroad flexo machine (including narrow, wide) and its own research and development and production of domestic narrow flexo total of 240 production lines, market share and on flexo products a step Dongguan color stickers printing process, additional color stickers printing company in Dongguan, in the process, flexo printing can be completed online coating, die stamping and other processing, reduce costs and improve production efficiency.
