摘要： In an ink jet printing apparatus that performs printing by using an ink and a processing liquid that renders the ink insoluble, an effect the mist of the processing liquid or substances insolubilized by it has on the ejection performance of the ink head or processing liquid head is reduced. The distance between the processing liquid head 101S and the print paper 103 carried by the belt 111 is set larger than the head-to-paper distances of other heads 101Bk, 101C, 101M, 101Y. As a result, the mist generated by the ejection of the processing liquid from the head 101S diffuses in a recessed space formed by the heads 101Bk and 101C on both sides of the head 101S and thus hardly reaches the ink nozzle surfaces of these heads on both sides.
摘要翻译：在通过使用油墨和使油墨不溶解的处理液进行打印的喷墨打印设备中，由于其不溶解的处理液体或物质的雾对油墨头或处理液头的喷射性能的影响是减少处理液头101S与带111携带的打印纸103之间的距离设定为大于其他头101Bk，101C，101M，101Y的头与纸的距离。其结果是，通过从头部101S喷射处理液而产生的雾在头部101S的两侧上由头部101Bk和101C形成的凹陷空间中扩散，从而几乎不到达两侧的这些头部的墨水喷嘴表面。

摘要： The present invention provides an ink jet printing apparatus and a preliminary ejecting method. In both a full-line and a serial printer, the amount of ink passing through nozzles of print heads is sometimes decreased below a normal value before and during actual printing, In the printer of present invention, a preliminary ejecting operation is performed taking the opportunity in which the amount of ink passing through nozzles is decreased below a normal value. Then, the amount of ink passing through nozzles recovers to the normal value at an ink ejection after the preliminary ejecting operation. Since only a small amount of ink is ejected through the nozzles during the preliminary ejection operation, dots formed on a print sheet are not noticeable. Further, it is unnecessary to move the print heads to a home position where an ejection recovering process is executed to remove ink having an increase viscosity.

摘要： An ink which includes a first pigment, a second pigment, a polymer dispersant and an aqueous medium; wherein the first pigment is a self-dispersing pigment having on its surface at least one anionic group bonded to the surface directly or via an atomic group, the second pigment is dispersed in the aqueous medium by the polymer dispersant, and the polymer dispersant contains benzylmethacrylate as a monomer unit. Diffusion of this ink in the printing medium is suppressed in the cross-sectional direction but not horizontal direction. Thus, the ink can form an ink dot that has a proper dot size, uniform and high density in the dot, with little feathering or blur.

摘要： High quality images showing an excellent fixation are formed by an ink-jet recording method using pigment inks. An ink set for the ink jet-recording method comprises a first ink containing an anionic dye in an aqueous medium, a second ink containing an anionic dye and having a lower coloring material content than the first ink and a dispersion destabilizing substance, and a third ink containing a self-dispersible first pigment, a second pigment and a polymeric dispersant for dispersing the second pigment in an aqueous medium. The dispersion destabilizing substance destabilizes the dispersion stability of at least either the first pigment or the second pigment in the third ink when the second ink and the third ink are brought into contact with each other. The second ink and the third ink are applied onto a printing medium one after another or substantially simultaneously so that they are brought into contact with each other in a liquid state on the printing medium.
