What's the difference between BB ink and BC ink?
Gravure printing ink is also called liquid gravure ink, the color is a kind of stable colloidal system, printing available appropriate the appropriate coating on the substrate, which renders the text pattern and color and provide information and attraction.
Gravure printing ink is mostly volatile solvent type ink, by pigment, solid resin, volatile solvents, filling material and additives. Gravure printing ink performance first to meet the needs of gravure printing process, and secondly, the ink transferred to paper or other materials on the film during the printing process, to be able to withstand the follow-up process and the use of various conditions. These properties include flow properties, optical properties, and resistance properties.
Like other printing inks, the main components of gravure ink are colored materials (pigments) and binders. Among them, colored materials play a role in color, depending on the color of the substrate to form a contrast, in the substrate to show images. Only the ink components proportion of the deployment, in order to achieve proper ink printability and the use of performance, to enable the good cooperation between the printing ink and printing plate, printing machine, printing materials, printing process smoothly.
