As a material of water-based ink, which is very important in printing work, what problems should be paid attention to in the preservation? Please see some of the following analysis:

The storage temperature of water-based inks is usually controlled at 5-30°C and cannot be stored in environments below 0°C. Can not be stored in open air, not exposure. The shelf life of gold and silver ink is generally not more than 6 months, and that of other water-based inks is generally one year. If it exceeds the shelf life, and the ink does not appear solidified colloidal state, but the surface layered or precipitated, after being fully stirred evenly, it can continue to use.

For the remaining ink after printing should be stored separately, sealed in a cool place. When it is re-enabled, the ink should be filtered with a mesh of 80 mesh or more to prevent inks or foreign materials from mixing and maintain the cleanliness of the ink.
