Ink is an important material for printing. It prints patterns, text, etc. on paper through printing. It is an essential material in the printing industry. Its performance directly affects the printing quality and production efficiency of the product.

(1) UV ink market analysis

At present, the most important application field of domestic UV ink is the printing of high-end cigarettes, wine, health care products and cosmetics packaging, accounting for more than half of it; followed by the printing of various trademarks, bills, etc.; the rest are some special materials or special purposes Printing of products, such as magnetic cards, plastic sheets and other products, and the trend of using UV printing technology for plastic sheets is constantly developing.

In recent years, LED UV curing technology has gradually emerged and is expected to become the mainstream curing technology in the future. The ink is cured using LED lamps, which have a very narrow wavelength range (currently mostly a single wavelength of 365~395nm). LED lamps have a longer service life, higher energy efficiency, and lower energy consumption. The LED lamps can be turned on and off instantly without preheating. , has extremely low thermal radiation and does not produce ozone. It is safer, more environmentally friendly and more energy-saving than the high-pressure mercury lamp used in traditional UV ink curing. According to market research agency Yole, the global LED UV market share in UV curing light sources will increase from 21% in 2015 to 52% in 2021. UV-LED inks have good development prospects in the future.

From the perspective of product structure, based on the good energy-saving and environmentally friendly performance of UV ink, my country's UV ink (including printing UV ink and solder mask UV ink, etc.) production accounted for an overall upward trend in the total domestic ink production. It has been on the rise from 2012 It increased from 5.24% to 9.17% in 2018, which is a rapid growth. It is expected that there will still be large room for growth in the future.

Only by correctly understanding and understanding the ink issues that need attention in printing can we appropriately adjust and improve certain properties of the ink according to the characteristics of the printing conditions during actual production operations, which will play a role in improving production efficiency and product quality. to better effect.
