This time, we'll discuss water-based ink, a crucial environmentally friendly raw ingredient used in printing. Binders,pigments, solvents, and auxiliary materialscombine to homogeneous paste in water-based ink. The ink's quality is directly affected by the major factors listed below. ✔1. The most crucial factor in ink application is viscosity which has a direct bearing on both the effectiveness of ink mobility and the standard of flexographic printing. ✔2. Alkali-soluble acid resin is the main type of binder used in water-based ink. The regulation of PH value is also important because PH value directly affects the viscosity of ink. ✔3. Thickness degree is the third indicator. It is the degree of dispersion of solid powder materials, such as pigments and fillers blended in the binders. ✔4. The general rule for choosing ink dryness is that the ink should be completely dry before next printing, rewinding and stacking except for the step of printing.
