Patent number: 9010909Abstract: A method of printing an image with a continuous inkjet printer system employing a jetting module including a nozzle in fluid communication with a liquid ink source and a catcher including a liquid drop contact face; wherein the liquid ink is an aqueous inkjet black ink comprising a black colorant and at least one surfactant selected to provide a 10-ms dynamic surface tension of less than 54 mN/m. Full color images may be printed by further employing at least second, third and fourth jetting modules and yellow, magenta and cyan inks each also comprising a surfactant selected to provide a 10-ms dynamic surface tension of less than 54 mN/m for each ink. The ink compositions provide for fluid properties on the drop catcher face that minimize printing defects that can occur during drop deflection during the printing of high dynamic range images at high speed.Type: GrantFiled: September 16, 2011Date of Patent: April 21, 2015Assignee: Eastman Kodak CompanyInventors: David John Nelson, Brian L Lindstrom, Alexandra DiLauro Bermel, Allan Francis Sowinski, David Louis Jeanmaire, Todd Russell Griffin

Patent number: 8784549Abstract: An aqueous inkjet ink set for use in continuous inkjet printing comprising at least one cyan ink, at least one yellow ink, at least one magenta ink, and at least one black ink, wherein each ink of the ink set comprises dispersed pigment particles and at least one surfactant selected to provide a 10-ms dynamic surface tension of less than 54 mN/m for each ink. The invention relates to continuous ink jet printing of aqueous pigmented ink compositions recycled from main ink supply reservoirs, employing a printer with drop ejectors and a drop deflector and non-printing drop catchers capable of returning unprinted ink to the fluid delivery systems following the capture of non-printing drops. The pigmented ink jet ink compositions provide for particularly suitable fluid properties on the drop catcher face that minimize printing defects that can occur during drop deflection during the printing of high dynamic range images at high speed.Type: GrantFiled: September 16, 2011Date of Patent: July 22, 2014Assignee: Eastman Kodak CompanyInventors: Alexandra DiLauro Bermel, Brian L Lindstrom, David John Nelson, Allan Francis Sowinski, David Louis Jeanmaire, Todd Russell Griffin
