Abstract

An inkjet printing method includes in order the steps of: a) providing to an inkjet printer one or more colorless liquids and a white ink including a pigment with a refractive index greater than 1.60; b) mixing the white ink in a controlled amount with the one or more colorless liquids to form a white ink-mixture wherein the viscosity is reduced by at least 5 mPa·s by reference to the white ink when measuring the viscosity at 40° C. with a Brookfield DV-II+Pro at 12 rotations per minute; and c) printing the white ink-mixture with the inkjet printer onto an ink-receiver. Additionally, a color inkjet ink set includes the one or more colorless liquids and the white ink, and an inkjet printer for use in the inkjet printing method.
