Abstract
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.
