What is the main composition of printing ink?

Ink is an indispensable material for printing commodity decoration and packaging. Through printing, the packaging surface becomes beautiful, colorful, exquisite and attractive. In recent years, with the rapid development of the printing industry, various plastic and paper packaging and printing have been continuously improved, and the requirements for product packaging are getting higher and higher.

At present, in the international market, inks are mostly composed of 20% to 40% binders ¹, 5% to 15% pigments ², 40% to 60% organic solvents ³ and 0% to 5% additives ⁴. 

1. The binder material is an adhesive resin, which is a key link component of the ink, which binds the pigment and the printed material together, plays an adhesion role, and makes the ink more glossy and shiny.  So far, iSuoChem has covered almost all ink resins in international markets, including Polyamide resin, Chlorinated PP resin, and other regular ink resins (More ink resins, check here: iSuoChem Ink resins).

2. Pigments determine the color category. 

iSuoChem is a leading manufacturer of effect pigments that are used in Printing ink industries. (More Pigments, check here: iSuoChem effect pigments).

3. The solvent dissolves the resin, adjusts the viscosity, adjusts the drying speed, and improves the wetting effect on the printing material. 

4. Additives play a role in improving viscosity, weather resistance, aging resistance, and increasing gloss. (More ink additives, check here: iSuoChem Ink additives).
