METHOD FOR NON-AQUEOUS INKJET PRINTING

摘要

PROBLEM TO BE SOLVED: To provide a method for non-aqueous inkjet printing, by which print density can be improved while using a non-aqueous post-treatment solution.SOLUTION: The method for non-aqueous inkjet printing includes a step of forming dots 10 of a non-aqueous pigment ink by discharging droplets of the non-aqueous pigment ink comprising at least a pigment and a non-aqueous solvent onto a surface of a print medium, and then discharging droplets 12 of a non-aqueous post-treatment solution comprising at least silica and an organic solvent toward the print medium so as to overlap the dots of the non-aqueous pigment ink. Either the non-aqueous pigment ink or the post-treatment solution contains a water-soluble resin having an amino group.
