Analysis of the current situation of label printing inks (III)

there is still a certain gap between domestic inks and imported inks, especially in high-end products. Domestic ink manufacturers should improve their technical level and production capacity as soon as possible to drive the improvement of the whole ink manufacturing industry. In order to achieve better preservation effect, the label printing ink should be stored in a closed container in a normal temperature, cool, dry, dark and ventilated environment. During the storage and management of label printing ink, we should also pay attention to the following problems:

"(1) safety first, store the ink away from fire and heat sources as far as possible to prevent accidents

(2) it is best to maintain a constant temperature in the ink warehouse, which should not be too different from the temperature of the printing workshop. 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 stability of ink performance, but also to ensure the high efficiency of production

(3) in some areas in the north, it is cold in winter, so we should avoid storing the ink outdoors to prevent the ink from gelling at low temperature. If gelation occurs, transfer it to a warehouse with high temperature, or put it into hot water to restore the insoluble matter to its original state

(4) the principle of "first in, first out" should be followed in ink storage and management, that is, the ink purchased first should be used first, so as to prevent the ink from affecting its use effect due to long storage time

(5) the ink also has a certain shelf life. If it is stored too long, various components in the ink will be separated and precipitated after being taken out and cooled to room temperature. Therefore, the sample ink with more personalized design should not be stored for a long time, and the general storage period is 1 year

(6) the remaining ink after printing must be sealed and stored in the dark. Before reuse, 10 systems must be used to promote the comprehensive standardization of intelligent manufacturing and the new mode, using the filtration of more than 0 mesh of the project, and then mixed with the new ink after full mixing

the label printing factory should effectively manage the label printing ink. The specific measures are: the label printing factory should generally set up a special material management department, which is responsible for the unified management of raw and auxiliary materials including ink, establish a perfect material management system, formulate reasonable incoming and picking procedures, and implement strict warehousing and outgoing procedures. That is, a specially assigned person is responsible for the management of ink, and the ink products are stored in different areas to avoid misuse. In addition, the type, origin, batch, quantity and requisition of ink should be recorded in detail to ensure the traceability of products
