More Information
Summary:A colour inkjet ink set comprising a white ink comprising a pigment with a refractive index greater than 1.60 and at least one colour inkjet ink characterized in that the viscosity of the white inkjet ink is at least 4 mPa.s greater than the viscosity of the colour inkjet ink wherein the viscosity is measured at 40° C with a Brookfield DV-II+Pro at 12 rotations per minute. Inkjet printing methods and inkjet printers are also disclosed.
