ABSTRACT:
A method for making a dispersion for an ink, and the ink obtained from this method. The method comprises preparing a dispersion comprising colorant agglomerates and reducing the agglomerate size using a plastic medium. The dispersion is formed by dispersing the colorant agglomerates in a dispersant, optionally in the presence of a liquid carrier such as distilled or deionized water. The colorant in the dispersion may be a carbon black, yellow, cyan, or magenta pigment, or a combination thereof. The plastic medium is preferably a grinding medium, such as polystyrene.
