Ink is an important material for printing packaging materials. It expresses patterns and characters on the substrate by printing. The ink includes main components and auxiliary components. They are uniformly mixed and repeatedly rolled to form a viscous gel-like fluid. It consists of pigments, binders and additives. For books, packaging, decoration, architectural decoration and other printing. As society's demand increases, the variety and output of inks also expand and grow accordingly.
Ink main components: color materials, connecting materials
Ink-assisted: fillers, thinners, anti-skinning agents, anti-printing agents, slip agents, other additives
In the process of storage and management, ink should pay attention to the following issues:
1. Safety First, keep away from fire and heat sources when storing ink to prevent accidents.
2. It is best to maintain a constant temperature in the ink depot, and the temperature difference from the printing shop should not be too different. If the temperature difference between the two is large, the ink should be placed in the printing shop in advance, which is not only beneficial to the stability of the ink performance, but also ensures the high efficiency of production.
3. In some areas in the north, winter is relatively cold. Avoid storing ink outdoors and prevent the gel from gelling at low temperatures. If gelation occurs, transfer it to a warehouse with high temperature, or put it in hot water to restore the insoluble matter.
4. In the ink storage and management should follow the principle of "first-in, first-out", that is, the ink purchased first is used first to prevent the ink from affecting its use effect due to the long storage time.
5. The ink also has a certain shelf life. If it is stored too long, various components of the ink will separate and precipitate. Therefore, the ink should not be stored for a long period of time. The general shelf life is one year.
6. After printing, the remaining ink must be sealed and stored in a dark place. Before reusing it, it must be filtered with a filter of 100 mesh or more, fully mixed and then mixed with new ink.
