Printing ink manufacturers have always had a demand for higher opacity of the white ink. The white printing ink development is even more challenging when the printing speeds are constantly increasing. How to produce brighter white when the layer thickness is less than 5 祄? And how to provide sufficient ink transfer, and smooth runnability in such a high speeds with low viscosity liquid inks? These are the ever open questions when developing white ink for the flexo- and gravure printing.
SACHTLEBN RDO is an answer for this printing ink industry demand. This new alumina treated rutile TiO2 pigment has a good combination of the desired properties for the printing inks applications. This pigment is easily wetted and dispersed in water and alcohol based systems. By proper formulation the ink manufacturer can obtain higher pigment loading in lower viscosity. Better dispersion of SACHTLEBEN RDO leads to trouble free manufacturing of the white ink and eventually for the excellent printability. This high opacity high gloss white ink layer made with SACHTLEBEN RDO is the fundamental part to make the print job to look brilliant.
