Large-format inkjet printing ink development survey and research analysis _ ink, inkjet printing _ domestic news

Takeaway: as the main material of large-format inkjet printing ink, its development to a certain extent, reflects the level of large-format inkjet printing technology. At present, inkjet ink, depending on the composition is divided into the total solids ink and total solid content in the ink. As the main material of large-format inkjet printing ink, its development to a certain extent, reflects the level of large-format inkjet printing technology. Chemical properties and formula of the ink is one of the determinants of printing image quality not only, also affect lis drops of spray characteristics and reliability of the imaging system. As a result, the image of the ink has often been compared to ink jet system of the blood. At present, inkjet ink, depending on the composition is divided into the total solids ink and total solid content in the ink. Among them, the total solid content is divided into ink solvent ink, water-based ink; Total solid content is divided into the UV ink and ink type hot melt ink. According to the use of different kinds of colorant, ink and pigment ink can be divided into the dye. UV ink in order to implement a large-format inkjet printing, high speed printing, the ink can must have a quick curing properties, and it is not easy to spread on the substrates. The large-format inkjet is the main application of UV ink. UV ink or UV curing ink, is letting light activity prepolymer as basic material of ink, the wavelength of 200 nm to 450 nm UV light irradiation, free radicals generated by the light initiator, cause polymerization and crosslinking reaction, make the ink from the liquid into a solid. The UV curing ink does not contain solvents, thus greatly eliminate the organic volatiles ( VOC） Pollution to the environment. In recent years, this kind of ink has been rapidly gaining market recognition, because of its on the absorbing medium such as metal, glass has good adhesion, can be achieved with rigid media platform printing machine combination to printing. World famous pine new market research company, according to a report in 2013 Western Europe UV inkjet print output value of about $2. 4 billion, to five years to 2018 to 13. The compound annual growth rate of 6% for growth, Britain will grow as fast into Western Europe countries, followed by Germany and France. Instantaneous solidifying, the use of low energy consumption, low pollution and good printing eligibility, and many other advantages to make the technology has been applied to many fields, the global UV inkjet printing is showing strong growth momentum. Predicts 2018, UV inkjet printing market application value of $15. 9 billion for its growth at 18. 3%. However, compared with the vigorous development of UV inkjet technology abroad, at present our country can independent manufacturer of UV ink is very few, mainly have to rely on imports, these imported inkjet ink prices are relatively high, so the cost of UV ink problem has always been a bottleneck of inkjet printing and related industry development in our country. How to develop a good, safe and stable performance of the ink color, get rid of the dependence on the high cost of imported ink, has become a problem urgently to be solved in the current domestic printing field. In recent years, we see more and more involved in the research and development of domestic ink enterprise, some has achieved initial success. Hongsheng digital station in zhengzhou, henan province, such as, on the basis of market demand, in order to transcend the existing LED - UV ink, replace imported ink as the goal, the development of the stable performance, meet the demand of market application, environmental protection and energy saving type edx5 LED - 395 The UV curing ink. The ink can be widely used in all kinds of materials, spray printing, has the good ink fluency and product stability, and fast curing and excellent printing eligibility. Hongsheng leds - UV inkjet ink can be used for EpsonDX5 generation of the print head, optimum printing a variety of materials, including plastic, acrylic, metal, wood, glass, crystal, porcelain, etc. Almost all of the hard material and soft material; Can complete mobile phone shell, electronic products, toys, gifts, membrane switch, signs and plastic, metal, glass, pottery and porcelain coloured drawing or pattern, wood, stone and so on the surface of the substrate printed. Traditional UV equipment can print materials or applicable field, LED - UV ink can be competent, and in traditional UV not good print of heat sensitive materials, and other fields, leds - UV can also reflects the greater advantage. In addition, the leds - UV ink multilayer printed form accumulation, but also presents the current tide of 3 d printing effect. Solvent ink solvent ink solvent in general is given priority to with organic solvent, its advantage is able to lower the cost of printing high weatherability outdoor print. Cheap solvent ink printing substrates, and in the request is not high, such as paper, plastic film, adhesive film and fabric without coating material on the spray print directly, using solvent inkjet printing printing quality without coated, saves time, and reduce the cost. But because of containing a higher proportion of volatile solvent ink organic material, easy to cause environmental pollution. Keyin network
