METHOD AND SYSTEM FOR IMPLEMENTING ADD-ON MODULE ON INKJET PRINTER TO PREVENT INK FROM SETTLING WITH ASSISTANCE OF MAGNETIC PARTICLES

摘要

PROBLEM TO BE SOLVED: To provide an ink composition and system that prevents a pigment-containing ink from settling and keeps the ink in a uniform dispersion state during a long running time in at least one of an ink reservoir and an ink passageway.;SOLUTION: A method comprises: adding a pigment, a surfactant, and a solvent into an ink reservoir to form an ink mixture; adding magnetic particles; and applying a varying magnetic field to the ink reservoir to create a chaotic motion of the magnetic particles throughout the ink mixture, to obtain a pigment-containing ink composition. The method further comprises applying a magnetic field to an ink passageway to create a chaotic motion of the magnetic particles.;COPYRIGHT: (C)2015,JPO&INPIT
