The printing of HD water-based ink is affected by many conditions, such as the surface characteristics of the substrate, the temperature and humidity of the environment, and the length of storage time. Therefore, when using it, you need to use some additives to make fine adjustments to the ink to achieve the best D. In addition, he is familiar with the characteristics and application methods of adjuvants in printing Chinese medicine.

1. The pigment is used to deepen the color, and its dosage is generally controlled at 0 to 30%. If it exceeds 30%, the binder in the ink will be too low, resulting in a decrease in its adhesion and wear resistance;

2. PH stabilizer is used to adjust and control the PH value of water-based ink to stabilize it between 8.0 and 9.5, which can ensure the printing state of HD water-based ink. At the same time, the viscosity of HD water-based ink can be adjusted and diluted;

3. The slow drying agent is used to reduce the drying degree of the ink. The slow drying agent can inhibit the slowing down of the drying speed of the water-based ink, prevent it from drying on the printing plate, and reduce the occurrence of blockage failure. And the amount of slow-drying agent is generally controlled at 0 to 10% of the total ink volume. If the amount is added too much, the ink will not dry completely, and the printed matter will produce peculiar smell;

4. HD water-based ink thinner is mainly used to reduce the depth of the color, and the amount is not limited, but if the amount is too much, the viscosity of the ink will increase. At this time, a small amount of diluent can be added to adjust;

5. The thinner is mainly used to reduce the viscosity of the ink, the dosage should be controlled within 3%, so as not to reduce the color depth of the ink, and to keep the pH value of the ink unchanged, the thinner should be slowly stirred while stirring Add it to prevent the viscosity from becoming too low. If you add more diluent or use tap water with high hardness to dilute, bubbles will be generated. At this time, you should add a defoamer;

6. The foam problem in the use of HD water-based ink is mainly because water is used as a diluent. A certain amount of emulsifier must be used during emulsion polymerization, which greatly reduces the surface tension of the emulsion system.
