The adaptability of ink and water is critical to the efficient production of printing shops. Why should we control the ink-and-ink balance? It is to control the technological process. The printing workers tend to let the process control them, and always solve it when it is out, rather than controlling the process to prevent problems.
Factors affecting the water quality of printing houses
Start to analyze step by step, breaking the assumption of "all water is the same" in the mind of the printing staff. Due to the different sources of water, the mineral content contained in them is also different. Example: Well and river water contain different minerals. The water from the faucet in the same printing plant is not always the same, although the difference between them from the same source water also affects the production work of the printing workshop throughout the year. "Other factors include:
The PH value of water is different, the ideal value should be 7.0;
Conductivity, which is based on the number of ions of minerals dissolved in water;
Chemical agents added by local water treatment companies, such as chlorine, fluorine, deodorant, etc.
Water and ink
On the printing press, we use a water bucket mixed with water. Therefore, it is critical to understand the composition of the water bucket. Bucket liquid is usually made of 98% water plus 2% of other mixing agents. The mixing agent is basically made of alcohol or alcohol, ink and wetting agent (active agent). If the amount of water in the bucket liquid is insufficient, it will not function properly.
Temperature is another factor that needs to be controlled. Temperature has little effect in process control. The higher the temperature, the lower the viscosity of the ink, and the amount of water and ink will increase. After the ink sticks to water, the viscosity will drop. Other influencing factors include what kind of substrate the job is printed on and the ink's date of manufacture.
The balance and adaptability of water and ink play the most critical role in the high efficiency and high-efficiency production of the printing workshop. However, different jobs at different times have their own unique process requirements, which brings serious challenges to printing production. You can follow the following principles to help achieve and control the ink and wash balance:
Install a water treatment system;
Replace ink to ensure quality;
Clean the printing plate before the printing plate to avoid contaminating the bucket liquid;
Perform routine maintenance on the printing press.
Summary: The better the control of ink and water, the better the printing effect. You also gain superior and constant control of the process.
