How to control the PH value and viscosity of water-based ink

The ph value of water-based ink is closely related to the PH value of water-based polyurethane resin, water-based acrylic resin or epoxy resin and related additives. The main resin is weakly alkaline, and the formula is weakly alkaline. The ink made of main resin is weakly acidic. The viscosity value is related to the added water-based thickener and filler. Relatively speaking, the more thickener is added, the thicker it becomes. Relatively speaking, the more filler is added, the thicker it becomes.
