What is the fluidity of ink
- 2022-09-28 15:09:02
- admin
The fluidity of ink includes viscosity, adhesion, viscoelasticity, and yield value and thixotropy.It mainly depends on the nature of pigment and binder, and its manufacturing process, the content of binder directly affects the fluidity of ink. In the printing press, the flow phenomenon is mainly manifested in the following three aspects: (1) When the container is poured into the ink...
