7 tips for long-term ink preservation, greatly saving costs
Factors affecting ink
Ink viscosity and dryness are particularly sensitive to ambient temperature changes. Temperature rise, ink viscosity is reduced, drying speed is relatively faster; On the contrary, the ink viscosity increases, drying speed becomes slow.
In addition, the environmental humidity also has an impact on the dryness of ink, generally speaking, the temperature control in the printing workshop at 18~25℃, humidity control at 55%~65% is appropriate.
Method of extending the storage life of ink
(1) The remaining ink after printing must be sealed and stored in the shade, and can be reused in the future production. Before re - use must first use more than 100 mesh filter filter, adequate mixing and new ink mixed use.
(2) in some areas in the north, the winter climate is cold, should prevent the ink stored outdoors, to prevent the occurrence of gelling ink at low temperature. If the ink gelling phenomenon, it can be transferred to a higher temperature in the warehouse. Or into the hot water, so that insoluble things can be restored to its original state.
(3) in the storage and management of ink should also follow the principle of "first in, first out", that is, the first purchase of ink first use, to prevent ink because of storage time is too long and affect its use.
(4) The ink is best sealed to prevent dust. A large number of dust particles or various impurity particles are likely to fall into the ink tank may be adsorbed on the surface of the label material, thus affecting the printing quality.
(5) Safety first, storage ink should be as far away from fire, heat source, to prevent accidents.
(6) It is best to keep a constant temperature in the ink warehouse, and the temperature difference between the printing workshop can not be too great. If the temperature difference between the two is large, the ink should be put into the printing workshop in advance, which is not only conducive to the stable performance of the ink, but also to ensure the high efficiency of production.
(7) Ink also has a certain shelf life, if stored too long, various components in the ink formula may occur dismantling, precipitation phenomenon. Therefore, ink should not be retained for a long time, the general retention period of about 1 year is appropriate, otherwise it may affect the printing quality, or even cause printing failure.
