In thermal printing ink, hydrophilic fumed silica speeds up the drying  pace, it helps avoiding smudged and blurred products caused by wet ink; In normal printing ink, hydrophobic fumed silica limits ink to adsorb water and removes foam, the color intensity improved while ink surface still shines; In gravure printing, flexography printing and silk printing, fumed silica works as anti-settling agent, and it can control the ink volume while printer is working for clean and clear printing results; In cartridge for printers, fumed silica works as dispersion agent and volume control agent. 

 

Ultra-fine precipitated silica by special treatment,with strong adsorption and good dispersion .It is mainly used as absorption,anti-setting and thickening agent in printing inks.etc.

 

Silicon Dioxide for ink-jet printing is absorbing material of colorful ink-jet base material surface coating, which is the coating’s undertaking material. Characteristics of silicon dioxide is the characteristics of surface coating. While printing, when the ink is jetted onto paper surface, moisture in it will be absorbed into inner surface coating, at the same time SiO2 absorbent in the coating will absorb the moisture quickly too. This makes the dye nonproliferation, not cross color, highly clear so that the picture distinguish ability is high and colorful.
