Birla Carbon offers carbon blacks that meet the color requirements of the newsink/coldest market. There is a balance between the desire for low viscosity inks, and ease of dispersion, which is primarily adjusted through the use of different levels of structure.
- Higher structure carbon blacks will favor dispersibility and give a higher viscosity
- Lower structure carbon blacks provide the lower viscosity, though these will be slightly harder to disperse
- The typical ink will be produced using locally sourced beaded carbon blacks, though some local markets still prefer powder carbon blacks even for newsinks.
