What's the difference between ink and pigment?

Ink is an important material for printing, and patterns and characters are displayed on the substrate through printing. Ink includes main components and auxiliary components, which are evenly mixed and repeatedly rolled to form viscous colloidal fluid. It consists of pigment, adhesive, assistant and solvent. Used for printing books and periodicals, packaging and decoration, architectural decoration, etc.

The difference between the two:

Coatings are water-based and can be dissolved in water, while inks are oily and can only be dissolved in lighter organic solvents.

Broadly speaking, paint is similar to ink, and is composed of resin binder (ink) or binder (paint), pigment, additives and so on. The difference should be the purpose of the application. The ink used in the printing industry is relatively fine, while the paint mainly plays a protective role, and sometimes it also plays a decorative role. There is no clear boundary between the two.
