Friends who make offset printing ink are still worried about choosing the type of resin? Let's take a look at rosin modified phenolic ink resin. The production of offset printing ink is determined by the offset printing machine. The principle of offset printing is oil-water separation. If other resins can not achieve oil-water separation effect at all,  rosin modified phenolic ink resin is widely used in lithographic inks because of its unique honeycomb structure characteristics, so it can be well wetted with pigments. Appropriate reaction with gel agent can obtain a certain strong adhesive binder.
