There are various dilution methods for water-based ink, and the specific method used depends on the required dilution effect, printing requirements, and the characteristics of the ink itself. Here are some common dilution methods:
1、 Dilute with clean water
Dilution ratio: It is recommended to add a ratio of 5% to 15%. This ratio can be adjusted according to actual needs, but a too high dilution ratio may affect the performance of the ink and the color of the printed pattern.
Characteristics: Water dilution is a simple and environmentally friendly method, but it may have a certain impact on the performance of water-based ink and the color of printed patterns after dilution.
2、 Dilute by mixing ethanol with water
Mixing ratio: The mixing ratio of ethanol and water is usually 8:2. This mixed solution can effectively dilute water-based ink while reducing its impact on ink performance and printing pattern color.
Characteristics: The addition of ethanol can improve the drying speed of ink, and due to the volatility of ethanol, it can help ink solidify faster on the substrate. However, it should be noted that ethanol is a flammable substance, and fire safety should be taken into account during use.
3、 Direct dilution with ethanol
Dilution ratio: It is recommended to add a ratio of 20% to 40%. This high proportion of ethanol dilution can better control the drying speed and flowability of ink, while reducing the impact on ink performance and printing color.
Characteristics: Direct dilution with ethanol can significantly accelerate the drying speed of ink, and due to the strong solubility of ethanol, it can better dissolve pigments, resins, and other components in ink. However, it should also be noted that the flammability and volatility of ethanol require strict adherence to safety operating procedures during use.
4、 Use specialized diluent
In addition to the above methods, diluents specifically designed for water-based inks can also be used for dilution. These diluents usually have better solubility and stability, which can better maintain the performance and printing effect of the ink. However, it should be noted that different brands and types of water-based inks may require the use of different types of diluents, so the selection of diluents should be based on the specific requirements of the ink.
5、 Precautions
When diluting water-based ink, the diluent should be gradually added and thoroughly stirred to avoid clumping or precipitation.
Diluted ink should be used up as soon as possible to avoid prolonged storage that may cause ink performance degradation or deterioration.
When using diluents, attention should be paid to their flammability and volatility, and corresponding safety measures should be taken to prevent accidents such as fires and poisoning.
There are various dilution methods for water-based ink, which can be selected according to actual needs. During the dilution process, attention should be paid to safe operation and control of ink performance to ensure printing effect and product quality.
