ABSTRACT:
The ink of the invention comprises a vehicle and a colorant. The colorant is a pigment that has been treated to reduce nozzle outs in the inkjet printers. The performance of these pigments is improved by forcing the pigment through an acute pressure valve process wherein the pigment is homogenized to a size of about 0.1 .mu.m.
