摘要：
A dry flushed pigment comprises a dry pigment and a flushing agent. Particles of the dry pigment are dispersed into the flushing agent. The dry flushed pigment may have at least 20 percent by weight dry pigment. The dry flushed pigment may have a range of 20 to 80 percent dry pigment by weight. A pigment concentrate comprising a dry flushed pigment and one or more of a group of an ink carrier, a dispersant, or a synergist, where the dry flushed pigment is mixed with one or more of the ink carrier, dispersant or synergist and then milled to create the pigment concentrate. The pigment in the pigment concentrate has a Z-average particle size in the range of 75 nm to 250 nm. The pigment in the pigment concentrates is present in the amount from about 15 to 60 percent by weight of the pigment concentrate.
