    • An aqueous inkjet black ink composition for use in continuous ink jet printing is provided comprising black pigment particles dispersed with a polymeric dispersant or self dispersing pigment particles without the need for a dispersant; and at least one surfactant, wherein the at least one surfactant is selected to provide the ink composition with a 10-ms dynamic surface tension of less than 54 mN/m. The invention relates to continuous ink jet printing of an aqueous pigmented ink composition recycled from a main ink supply reservoir, employing a printer with a drop ejector and a drop deflector and a non-printing drop catcher capable of returning unprinted ink to the fluid delivery system 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.
    • 提供用于连续喷墨印刷的水性喷墨黑色油墨组合物,其包含分散有聚合物分散剂或自分散颜料颗粒的黑色颜料颗粒,而不需要分散剂; 和至少一种表面活性剂,其中所述至少一种表面活性剂被选择以使所述油墨组合物具有小于54mN / m的10ms动态表面张力。 本发明涉及从主油墨供应储存器再循环的水性着色油墨组合物的连续喷墨印刷,采用具有滴液喷射器的打印机和液滴偏转器以及能够将未印刷的墨水返回到流体输送系统的非印刷液滴捕集器 捕获非印刷液滴后。 着色的喷墨油墨组合物在液滴捕集器表面上提供特别合适的流体性质,使得在高动态范围图像的高速印刷过程中在液滴偏转期间可能发生的印刷缺陷最小化。

    • 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.
    • 一种用于连续喷墨印刷的含水喷墨油墨组合物,其包含至少一种青色油墨,至少一种黄色油墨,至少一种品红色油墨和至少一种黑色油墨,其中所述油墨组中的每种油墨包含分散的颜料颗粒,并且 选择至少一种表面活性剂为每种油墨提供小于54mN / m的10ms动态表面张力。 本发明涉及从主要油墨供应储存器循环使用的水性着色油墨组合物的连续喷墨印刷,采用具有液滴喷射器的打印机和液滴偏转器以及能够将未印刷油墨返回到流体输送系统之后的捕获 非印刷滴。 着色的喷墨油墨组合物在液滴捕集器表面上提供特别合适的流体性质,使得在高动态范围图像的高速印刷过程中在液滴偏转期间可能发生的印刷缺陷最小化。
