Classification Of Water-based Inks

Classification of inks Modern inks are mainly divided into four categories according to the type:

2. lithographic ink
A class of inks suitable for lithography. Each part of the lithographic layout is basically in a plane, the pattern is oleophilic, the non-pattern is hydrophilic, and the printing is performed by the principle of oil and water repelling, so the lithographic ink must have water resistance.

3. Gravure ink
