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： 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： 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： A method for adjusting an amount of discharge is to adjust the amount of liquid between liquid discharge units to discharge the liquid by driving a plurality of electrothermal transducing elements, which uses a plurality of liquid discharge units arranged corresponding to each liquid path for the creation of air bubbles for discharging the liquid, at the same time, being arranged to be capable of being driven individually. This method comprises the step of variably controlling the starting time of driving signal applied to each of the electrothermal transducing elements for the creation of air bubbles in each of the discharge units. The variable control thereof makes it possible to suppress the variation of discharge amount of liquid between the liquid discharge units, hence maintaining the amount of liquid discharged from each of the discharging units at a constant level to obtain printed images of higher quality.
