The viscosity and dryness of ink are particularly sensitive to changes in environmental temperature. As the temperature increases, the viscosity of the ink decreases, and the drying speed relatively increases.
On the contrary, the viscosity of the ink increases and the drying speed slows down. In addition, environmental humidity also has an impact on the dryness of ink. Generally speaking, it is advisable to control the temperature in the printing workshop at 18-25 ℃ and the humidity at 55% -65%.
Methods to extend the shelf life of ink
1. In some northern regions, the winter climate is extremely cold, so it is advisable to avoid storing ink outdoors to prevent gelation at low temperatures. If the ink undergoes gelation, it can be transferred to a warmer warehouse.
2. In the storage and management of ink, the principle of "first in, first out" should also be followed, that is, the ink purchased first should be used first to prevent the ink from being affected by prolonged storage time.
3. Ink sealed storage to prevent dust. A large number of dust particles or various impurity particles are likely to fall into the ink tank or adsorb onto the surface of the label material, causing nozzle blockage.
4. Safety first, when storing ink, it should be kept away from sources of fire and heat as much as possible to prevent accidents.
5. It is best to maintain a constant temperature in the ink warehouse, and the temperature difference between it and the printing workshop should not be too large. If the temperature difference between the two is large, the ink should be placed in the printing workshop in advance, which is not only beneficial for the stability of ink performance, but also ensures high production efficiency.
6. Ink also has a certain shelf life. If stored for too long, various components in the ink formula may break down and precipitate. Therefore, ink should not be retained for a long time, and the retention period is generally around 1 year, otherwise it may affect the printing quality and even cause printing failures.
