How to control the viscosity of Printing ink in plastic gravure printing?

With the continuous development of plastic ink technology, it is widely used in flexible packaging, and the quality requirements for plastic film printing are also increasing. Today, plastic film printing mainly includes several printing methods such as flexo printing and gravure screen printing. Among them, in the gravure plastic film printing process, the control of ink viscosity directly affects the quality of printed matter, especially in high-speed rotogravure printing, if the ink viscosity is controlled properly, it will directly affect the transfer of pigments, dirty plates, and the glossiness of printed matter. , Pigment drilling firmness, static electricity and most other quality problems are related, and affect the yield of printed products and work efficiency. How to properly control ink viscosity can achieve multiple considerations to ensure product quality, cost and speed, etc. This requires construction personnel to fully understand ink viscosity and the influencing factors of ink viscosity, so as to ensure reasonable control of ink viscosity during printing.
