Anti-viscosity is an important physical property index of printing ink.Gravure printing is a kind of printing method with high ink supply, good reproducibility and fast printing speed. Most of the inks used are solvent-based volatile drying inks.After the ink is transferred to the substrate through the printing plate, it passes through the drying channel, and the organic solvent is quickly volatilized and dried.

As we all know, when winding through the high temperature baking channel, the surface temperature of the printing film is generally between 40 ° C and 60 ° C, and due to the existence of the winding pressure, if the anti-anti-viscosity of the ink itself is not good, it will lead to serious quality accidents of winding and adhesion, causing irreversible economic losses to ink customers.

The anti-anti-viscosity of the ink is not only related to the thoroughness of the solvent gradient volatilization in the printing process, but also directly related to the film formation of the resin binder used and the molecular properties of the resin. Good film forming resin bonding material can give the ink good dry, after the solvent volatilization and thorough drying, the film formation is complete, and the anti-viscosity after winding is excellent.
