Reasons: ① Migration caused by free resin in the ink system, especially migration or deformation caused by the softening point of the thermoplastic resin binder is too low or the ambient temperature is too high; ② is the penetration often refers to the color in the packaging printing ink system 1. The penetration caused by the characteristics of the dye is also due to the substrate itself is not resistant to penetration, followed by too little ink resin connection will also cause penetration. Especially the result of the turbidity caused by the imbalance of the solubility between the solvent and the resin, and the pigment particles cannot be tightly coated (reactive) on the surface (active) in the competitive adsorption.
