Water-based ink refers to an ink system formed by dissolving water-soluble dyes or uniformly dispersing organic pigments in "water" or "mixed liquid of water and organic solvent" as a carrier.

According to the different color formers used, water-based inks can be divided into dye-based water-based inks and pigment-based water-based inks. In the dye-based water-based ink, since the dye is dissolved in the carrier, each dye molecule is surrounded by the carrier, so no particulate matter can be observed under the microscope. The dye-based water-based ink has low optical density, no pollution, and light fastness. The water resistance is poor, but the output image has a wide variety of colors and high vividness.

In pigment-based water-based inks, the pigment is dispersed in the carrier in the state of loose and fine particles. Usually, the pigment particles need to be treated with a dispersant or a stabilizer to prevent the pigment from forming agglomerates and causing precipitation. The water resistance and light resistance of pigments are much stronger than that of dyes.

Water-based ink is an environmentally friendly ink that does not contain volatile organic solvents. Therefore, it does not pollute the atmosphere and will not cause harm to the body of ink manufacturers and printing operators. Since the linking material uses water, the water has a long drying time on the substrate, but it has a tendency to dry quickly in the nozzle of the inkjet head. Therefore, frequent maintenance of the nozzle is required. Water-based ink is suitable for porous permeability and non-coating. on cloth substrates, such as cardboard. Sometimes in order to obtain the best printing effect and durability outdoors, special and very expensive printing materials are required, and lamination treatment is required, so the application of water-based inks is also limited.

With the increasing pressure of environmental protection, the development of water-based ink will have more and more room for development. Environmentally friendly organic pigments dedicated to water-based ink will also be more and more favored by customers.
