Packaging printing ink manufacturing

During the printing process, the ink is transferred from the printing plate or stencil to paper or other printed materials, presenting the graphic on the print. In fact, as early as 2000, the Chinese made inks and printed them on ink in woodcuts.

Most inks consist of pigments, binders, and ink transfer agents.

The colorant is a component that gives the ink its color. Most of the pigments are made of rocks and clay, while others are from plants, marine life and even insects. Several colorants can also be mixed together to obtain a certain desired color of ink.

The binder is the fluid that carries the colorant. Oil, varnish, alcohol, and water can all be used as a binder.
Ink transfer agents can be added to the ink to achieve certain desirable properties. For example, a desiccant can speed up the drying of the ink; a wax can be used to reduce stickiness on the back.

Ink manufacturing:

Raw material preparation, including the selection and processing of the required colorants, binders and ink transfer agents before mixing;

Mix all ingredients according to the amount to be dispensed in the toner container;

The mixed ink is transferred to a grinder, and the grinder refines the solid particles in the mixture to make it more evenly dispersed in the binder;

After grinding, the ink is inspected to ensure that the batch of ink has the characteristics that one would expect in real printing conditions;

Packaging is the last link in the manufacture of ink: ink can be contained in hoses, cans or drums. For manufacturers that require a large amount of ink, they can be transported to users using tank trucks.
