Information shows that in 1951, the first application of inkjet The printing principle printer successfully prints out characters. If this is the starting point, inkjet printing has been developed for more than 60 years. During this period, technology has developed rapidly and the application field has been expanding. At present, with the adjustment of national industrial policies, the increasing emphasis on environmental safety by the nationals, and the increasing pressure on environmental pressures, we are also exploring how to make inkjet printing healthy and green when we are working on the development of inkjet technology. Sunshine industry development.
Green development, ink first
When it comes to the green development of the inkjet printing industry , the first thing to do is inkjet ink. At that time, there were few domestic inkjet printing circles in the software, nozzles and ink supply systems, but the production of inkjet inks was vigorous, and regular manufacturers could basically follow the light industry standards released by the National Development and Reform Commission in 2005. "Inkjet printer ink" and other standards for production, not only its products are used in a variety of inkjet printing equipment , and even some foreign brands also let Chinese ink manufacturers provide OEM production.
With the development of inkjet inks and inkjet printing equipment, the application fields of inkjet printing have gradually expanded to decorative decoration, ceramic sanitary ware, advertising production, textile printing and dyeing, packaging printing , toy stationery and so on. While we are enjoying the wonderful products brought by inkjet printing, we are also beginning to worry about environmental protection and safety. Based on the reality that traditional inks, especially VOCs in gravure inks, exceed the standard, society has some negative views on the ink and printing industries. In fact, many ink companies in China have realized that they want to introduce products that are conducive to environmental sustainability, and increase investment in research and development in terms of UV inks and water-based inks. At present, domestic UV inkjet has matured to the market and achieved good economic and social benefits.
Industry development "one two three"
The development of green printing of inkjet printing is an inevitable trend, but how to proceed, the author believes that from the industry to the enterprise, from the standard to the product, the following three aspects.
1. Comply with national laws and regulations, and strive to develop green inkjet
Comrade Xi Jinping pointed out in the report of the 19th National Congress that it should speed up the establishment of a legal system and policy orientation for green production and consumption, and establish and improve an economic system with a green and low-carbon cycle. Construct an environmental governance system with government-led, corporate-themed, social organization and public participation. Actively participate in global environmental governance and implement emission reduction commitments.
The greening of inkjet printing is relatively environmentally friendly in a broad sense. The industry should ban certain solvents when formulating inkjet printing production R&D standards, significantly reducing harmful components such as aromatic hydrocarbons, glycol ethers and esters, and ensuring that it does not contain lead, arsenic, antimony, chromium, cadmium, mercury, selenium, etc. Heavy metals, do not contain chemicals that are harmful to the human body, such as polybrominated diphenyl ethers specified by ROSH. In addition, we should vigorously promote the development of safe and environmentally friendly UV inkjet, UV LED inkjet and water-based inkjet, pay attention to the migration of pigments and some low-viscosity reactive diluents in the selection of raw materials, respect and protect the intellectual property rights of the inkjet industry. Heavy penalties for companies that violate national environmental regulations.
