摘要： A secondary color is used for printing an image with a printer so as to reduce the granularity of the printed image, particularly the light image area. Data of magenta and cyan color components of image data is subjected to under-removal processing to generate blue ink image data as the mentioned secondary color. A blue ink dot is printed in accordance with the blue ink data obtained by the under removal processing to replace the magenta and cyan data. As a result, it is possible to reduce the granularity that would otherwise be caused by localized distributions of magenta and cyan dots.

摘要： An ink jet printing method and apparatus using a color ink and a print performance improving ink which minimizes an image quality degradation due to blank lines formed by failed or faulty nozzles. This system enables the use of a print head even with failed or faulty nozzles by minimizing the image quality degradation and extends the life of the print head before replacement. The print performance improving ink is deliberately ejected onto a blank line or its vicinity to produce the so-called primer effect, thereby inducing the color ink dots on the lines adjoining the non-ejecting nozzle line to spread into the blank line to make the blank line undistinguishable.

摘要： In an image printed by a printing apparatus, graininess particularly in a light part of the printed image is reduced by relatively simple structure by using a second color. To do so, magenta and cyan color component data in image data is subjected to under color removal to generate image data of a blue ink being the secondary color. On the basis of the data of the blue ink replaced for magenta and cyan, printing is performed by forming dots of the blue ink. At this time, black data is distributed into dark black and light black by density distribution, and the light black is substituted by the blue and yellow inks, whereby it is possible by the simple structure to prevent the graininess appeared when the cyan and magenta dots mutually appear biasedly and the graininess due to the black ink dots.

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： 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.
