Water-based ink, which can be diluted with water or ethanol, can be rinsed with tap water, but can form a water-resistant film after drying on the substrate

Foams are dispersion systems in which gas is dispersed in a liquid

When the foam is formed, the surface area of the liquid increases, and the energy of the system increases; when the foam is destroyed, the surface area of the liquid decreases, and the energy of the system decreases.

Water-based inks are liquid inks, which are much thinner than offset inks, and are easily mixed with gas during the ink printing transfer process to generate foam

The use of antifoams is in conflict with measures to improve foam stability

It can be used in both aqueous and non-aqueous systems
