METHOD FOR PRODUCTION OF A DIGITAL PRINTING INK AND INK OBTAINED

摘要

Procedure for the production of a digital printing ink and the ink thus obtained. It is characterised in that it comprises the following phases: a first phase in which at least one dispersant, one pigment and one vehicle is mixed with a high-shear stirring system, a second pre-grinding phase to produce a particle size of less than 3 microns, a third grinding phase to produce a particle size of less than 1 micron, controlling the applied energy to prevent charging the particles with energy, a fourth filtration phase employing a 1-micron filter and a fifth phase in which the ink resulting from the fourth phase is packaged.
