What is Gravure Ink? Gravure (Rotogravure) inks are solvent-based ink with low viscosity, which can be quickly dried by vaporization. The advantages of gravure printing lie in the high, consistent, and continuously reproducible print result. Further, the benefit of fast-drying ink contributes to an immediate post-finishing of the printed goods. The ink is usually used in commercial printing of fle...

Flexo (Flexography) Inks are inks transferred by the process of flexography, primarily used in the printing of packing materials, for example, cardboard boxes, brown corrugated cardboard, paper bags and plastic bags, newspapers, etc. There are several types of ink which are mainly water-based, solvent-based, and UV curable. The flexo inks, like Gravure inks, have low-viscosity, characterised as fl...

The liquid part of the ink composition is called the adhesive; Solids are pigments (pigments or dyes); And various additives. Adhesives are gel-like fluids with a certain viscosity. Its function was first as a carrier for pigments. Powdered pigment and other solid particles are mixed and connected, and the pigment is evenly dispersed in it by its wetting action, which makes fine grinding on the gr...

1. Excellent yellowing resistance During the preparation process, polyurethane resin for printing ink is mainly synthesized from aliphatic polyester and aliphatic isocyanate as the main raw materials. Compared with aromatic polyurethane, it has excellent optical stability and excellent yellowing resistance after film formation. 2. Excellent adhesion fastness to film substrates The polyurethane res...
