With the advancement of the printing industry, printing technology and printing equipment have been continuously improved. Among them, offset printing has its unique advantages. For example, rapid and convenient plate making, low cost, high printing quality, wide paper use, and reduced printability. Dajiu has gradually received the attention and development from domestic and foreign printing manufacturers, which has led to rapid and extensive development. As a result, offset printing has dominated the international printing industry, and offset printing inks have also developed rapidly. In order to meet the needs of various printing equipment, substrates, and various packaging and decoration products, publishing and printing, offset printing inks are increasingly being used, the level of ink manufacturing technology is continuously increasing, and the output of inks is increasing. According to relevant information, currently offset printing inks account for about 40% of the total amount of printing inks, and this proportion will not change much within a certain period of time.

First, the market status of offset printing ink

In recent years, with the development of the world economy and the continuous improvement of people’s cultural life, the ink industry in the industrially more developed countries has also experienced rapid development, and the printing and publishing industry and printing and decoration products have gradually developed toward diversification and gentrification.

According to statistics, in the ink production of more developed countries, offset printing ink products mainly include offset bright fast drying ink, non-heat solid offset rotary printing ink, press rotation ink, etc., followed by ultraviolet drying ink and infrared drying ink. Synthetic paper offset printing ink, iron printing ink, anhydrous printing ink and various special inks for offset printing.

In order to meet the user's requirements for quality and price in different grades, according to the main printing requirements, including: color, density, dryness, water resistance, printing speed, on-board stability and other major ink quality indicators have launched different grades. The inks are available to the user for full selection.

The renewal of ink production equipment and the improvement of production technology have also gradually received the attention of manufacturers.

In the past ten years, major domestic ink manufacturers in Tianjin, Shanghai, Hangzhou, Shenzhen, Taiyuan and other places have paid attention to collecting market information and continuously developing marketable new types of offset ink products, such as: Inks, cardboard inks, matt powder inks (glossy inks), press rotation inks, coldset offset transfer inks, UV curable inks, offset synthetic paper inks, iron printing inks, and the latest in domestic heat in recent years The output of solid offset transfer inks and other products has been increasing year by year, and the quality has caught up with or approached the international advanced level, and has been recognized by printing customers at home and abroad.
