Method of extending ink shelf life

1. The ink remaining after printing must be sealed and stored in the dark, and can be reused in future production. Before re-use, it must be filtered with a filter of 100 mesh or more, and mixed with new ink after sufficient agitation.

2, in some areas in the north, the winter climate is very cold, should prevent the ink from being stored outdoors, to prevent the ink from gelling at low temperatures. If the ink gels, it can be transferred to a warehouse with a higher temperature, perhaps placed in hot water, so that the insoluble matter can be restored to its original state.

3. In the storage and management of ink, the principle of “first in, first out” should also be followed, that is, the ink purchased first is used first to prevent the ink from affecting its application due to long storage time.

4, the ink is best sealed to prevent dust. A large number of dust particles or various foreign particles are likely to fall into the ink tank or may be adsorbed on the surface of the label material, thereby affecting the printing quality.

5, safety first, when storing ink should be as far away as possible from fire sources, heat sources, to prevent accidents.

6. It is best to keep the temperature in the ink warehouse, and the temperature difference with the printing workshop should not be too great. If the temperature difference between the two is large, the ink should be placed in the printing workshop early, which not only helps the ink performance to be stable, but also ensures high production efficiency.

7. The ink also has a certain shelf life. If the storage is too long, the various components in the ink formulation may be disassembled and precipitated. Therefore, the ink should not be retained for a long time, and the general retention period is about 1 year, otherwise it may affect the printing quality and even cause printing failure.
