As a key player in the transition from traditional printing to digital printing, the development of pigment printing technology has always been highly regarded. In the traditional printing field, coatings account for over 60% of the market share, but in digital printing, less than 10% of machines use coating ink. By 2024, in addition to significantly increasing the printing speed from 50 meters per hour to over 1800 meters per hour, pigment printing has made many key technological breakthroughs in ink, print heads, and processes. Integrated (one-step) digital printing technology has become a reality, and pigment printing is rapidly moving towards digitization.

The initial coating ink particles were large, incompatible with the print heads at that time, and had poor fastness, requiring separate pre press coating and post press heat curing and softening treatment. These additional processes, coupled with slower printing speeds, made digital printing with coatings unattractive at the time. Later, with the development of new coating ink formulations by companies such as Kangli and DuPont, the issues of uniformity, stability, and volume velocity of early coatings have now been resolved.

Xaar Aquiox print head：

The paint print head has also experienced a leap in development, with Xaar’s ultra-high viscosity technology AquiNOx capable of spraying fluids with viscosities up to 100cP. Due to a wider color gamut, larger fluid particles, and more coatings, the opacity is higher, the colors are more vivid, and white and black are also more vivid.

Ricoh Large Ink Drop G6 Print Head：

Ricoh has developed three industrial grade inkjet print heads, namely RICOH MH5422, RICOH MH5442, and RICOH MH5422Type A. By adopting Ricoh’s high-precision technology, it can provide high image quality and productivity. In addition to having extensive ink compatibility, Ricoh has also improved durability by enhancing the wear resistance of the printhead surface. In addition, Ricoh has improved system compatibility by applying independent cables and high-precision surface calibration functions.

Nowadays, more and more printing factories are gradually realizing the potential and advantages of coatings compared to active/acidic/dispersed printing, and are beginning to adopt one-step digital printing technology to achieve rapid market launch and production. Based on the current annual growth rate of over 16%, pigment printing is expected to achieve rapid development in the coming years. In addition, with the continuous improvement of the speed and fastness of pigment printing, the pigment ink market will also see significant development.
