6 tips for long-term ink preservation
01 What should I do if I don’t use up my ink? How do I store ink? What is the most suitable storage environment for ink? What are the ways to extend the shelf life of ink? Here are the detailed answers for you.
02 Ink viscosity and dryness are particularly sensitive to changes in ambient temperature. When the temperature rises, the ink viscosity decreases and the drying speed becomes relatively faster; conversely, the ink viscosity rises and the drying speed becomes slower.
03 In addition, environmental humidity also has an impact on the drying of ink, in general, the temperature in the printing shop is controlled at 18 ~ 25 ℃, humidity control at 55% ~ 65% is appropriate.
Ways to extend the shelf life of the ink
01 In some northern regions, the winter climate is cold, you should avoid storing the ink outdoors to prevent the ink in the low temperature gelling phenomenon. If ink gelling occurs, it can be transferred to a storage room with a higher temperature.
02 In the storage and management of ink should also follow the principle of “first in, first out”, that is, the first purchased ink is the first to use, to prevent the ink from being stored for too long and affecting its use.
03 ink sealed and stored to prevent dust. A large number of dust particles or various impurity particles are likely to fall into the ink slot or perhaps adsorbed in the label material appearance, thus causing nozzle blockage.
04 Safety first, the storage of ink should be as far away as possible from the source of fire, heat sources, to prevent accidents.
05 ink storage room can best be maintained at a constant temperature, and the temperature difference between the printing workshop can not be too disparate. If the temperature difference between the two is large, the ink should be put into the printing workshop early, not only to help the ink performance is stable, but also to ensure the high efficiency of production.
06 ink also has a certain shelf life, if stored too long, the various components of the ink formula may occur in the dismantling, precipitation phenomenon. Therefore, the ink should not be retained for a long time, the general retention period of about 1 year is appropriate, otherwise it may affect the print quality, or even cause printing failure.
