Description

Technical Field

[0002] Offset printing is the most important printing method at present. Its characteristic is that fountain solution is needed in the printing process, so offset ink is required to have good water resistance. In the production process of offset ink, stirring is a very important step, and its purpose is to quickly stir the mixture evenly, so as to produce offset ink of qualified quality.

[0003] During the production process of offset ink, rosin-modified resin needs to be added to vegetable oil, and then the temperature is raised to 150°C to dissolve the rosin-modified resin and mix with the vegetable oil.
