About printing ink, how to save it?
The ink remaining after printing must be sealed and stored in the shade, which can be used in future production. Before re - use, you must filter with more than 100 mesh screen, mix thoroughly, and then mix with new ink.
Ink also has a certain shelf life, if deposited too long, the ink formulation of various components may occur separation, precipitation phenomenon. Therefore, the ink should not be long-term preservation, the general storage period of about 1 years is appropriate, otherwise it may affect the quality of printing, and even cause printing failure.
In the storage and management of ink, should also follow the "first in, first out" principle, that is, the first purchase of ink first, in order to prevent the ink because of the storage time is too long and affect its use.
(1) safety first, when storing ink, should keep away from fire source and heat source as far as possible, in case of accident.(2) the best to keep the temperature in the ink warehouse, and the printing workshop temperature difference can not be too great. If the temperature difference between the two should be greater, the ink should be put into the printing workshop in advance, not only conducive to the stability of ink performance, but also to ensure high production efficiency.(3) in some areas of the north, the climate in winter is rather cold, and the ink should be kept outdoors, so that the ink can not be gelled at low temperature. If the ink is gelled, it can be transferred to a higher temperature warehouse, or placed in hot water, so that the insoluble matter can be restored to its original condition.
