The remaining ink after printing must be sealed and stored in a dark place,

which can be reused in future production. Before reuse, it must be filtered

with a filter screen of more than 100 meshes, and mixed with new ink after

sufficient mixing. In some regions in the north, the winter weather is very cold,

so it is necessary to prevent the ink from being stored outdoors to prevent

the ink from gelling at low temperatures. If the ink gelling phenomenon occurs,

it can be transferred to the warehouse with higher temperature, or placed in

hot water to restore the insoluble.

The principle of "first in, first out" should also be followed in the storage and

management of ink, that is, the ink purchased first should be used first to prevent

the ink from being stored for too long and affecting its use. Methods for prolonging

the storage life of printing ink.The ink should be sealed to prevent dust. A large

number of dust particles or various foreign particles are likely to fall into the ink

tank or be adsorbed on the surface of the label material,thus affecting the printing

quality. Safety first, when storing ink, keep away from fire and heat sources as far as

possible to prevent accidents.

Methods for prolonging the storage life of printing ink.It is better to keep

constant temperature in the ink warehouse, and the temperature difference with

the printing workshop should not be too wide. If the temperature difference between

the two is large, the ink should be put in the printing workshop early, which is not only

conducive to the stability of the ink performance, but also to ensure the high efficiency of

production. Ink also has a certain shelf life. If it is stored for too long, various components

in the ink formula may be disassembled and precipitated. Therefore, the ink should

not be retained for a long time. Generally, the retention period should be about one year.

Otherwise, the printing quality may be affected, and even printing failures may occur.
