A white ink that can be printed by inkjet is often desired for niche applications. However, the market situation is very unsatisfactory. The reason for this is the difficulty of blending a white pigment with high opacity, e.g. titanium dioxide, with this technology. This is because high opacity means large particle diameters - and the printer nozzles are narrow. On the other hand, white pigments are heavy - they have quite a high density - and therefore they fall out after a short time, they are said to sediment. We are trying to solve these problems by changing the surfaces of known white pigments on the one hand, and also striving to develop completely new pigments on the other.
