Abstract: A method for use with dye-based ionic ink jet inks is disclosed whereby the ink jet ink becomes substantially waterfast upon application to a print substrate. The method includes treating a print substrate with a precipitant composition and jetting an ionic ink jet ink onto the print substrate, wherein the precipitant composition includes water and an ionic precipitant of opposite ionic charge from the ionic ink jet ink. The print substrate may be treated during formation of the print substrate or after formation of the print substrate and before jetting the ionic ink jet ink onto the print substrate. By this method, the ionic precipitant composition reacts with the oppositely charged ionic ink jet ink to form a precipitant on the print substrate that is substantially waterfast.

Abstract: Processes are disclosed for fabricating an ink composition which uses a high pressure shearing force to produce a desired reduction and dispersion of pigment particles in a concentrated dispersion. In one disclosed process, an aqueous ink mixture including water, a solvent and a black pigment colorant dispersion is processed by a microfluidizer and filtered to obtain a desired particle size making the ink suitable for ink jet printing applications. In another process, the pigment dispersion is first microfluidized and the water and solvent added to form a mixture which is then filtered. These processes simplify the ink fabrication by eliminating a sonification and centrifugation step required by prior art processes.
