  • Patent number: 8147020
    Abstract: An ink-jet recording method is provided. The ink-jet recording method includes (i) supplying an aqueous treatment liquid containing a fixing agent for fixing the components contained in an aqueous ink, on an art paper or a coat paper, in an amount of from ?50% to +30% with respect to the value of ?V [ml/m2] determined by the following formula (I), and (ii) recording an image by ejecting an aqueous ink containing a colorant, resin particles, an aqueous organic solvent and water, on the art paper or coat paper by an ink-jet method. In Formula (I), Vr represents a roughness index of the art paper or coat paper obtained from a measurement of liquid absorbability according to the Bristow method, and Vi represents an amount of transfer at the inflection point where the value of the absorption coefficient of the art paper or coat paper changes in the measurement of liquid absorbability according to the Bristow method.

  • Patent number: 8149456
    Abstract: Restriction information on a total colorant amount for a medium is obtained. Patches at grid points in a color space corresponding to a plurality of colorants at which the total colorant amount falls within a restriction represented by the restriction information, and a patch at a point surrounded by the patches are generated. Color values are obtained by measuring the colors of the patches printed on the medium. It is determined based on a color prediction value between the grid points whether the measured color values are appropriate, and if so, a color value at a grid point at which the total colorant amount exceeds the restriction is estimated based on the measured color values. A color separation table is created based on the measured color values and the estimated value.

  • Patent number: 8139245
    Abstract: An approach is provided for managing the processing of print data at a printing device based upon available consumable resources. A printing device includes a print process configured to determine consumable resources that are currently available at the printing device. The print process is further configured to determine which print data is to be processed based upon the consumable resources currently available at the printing device and the consumable resources required to completely process each of the print data. Print data that can be completely processed using the currently available consumable resources are selected for processing. The print process may also be configured to cause a notification to be provided to a client device to indicate the consumable resources currently available at a printing device and/or that insufficient consumable resources were available to process particular print data and to recommend other consumable resources to process the particular print data.

  • Patent number: 8118393
    Abstract: A method of removing foreign particulates from an ink ejection face of a pagewidth printhead mounted on a substrate. The substrate has a film guide positioned adjacent the printhead. The method comprises the steps of: (a) flooding the face with ink and dispersing the particulates into the flooded ink; (b) positioning a polymer film in a transfer zone so as to define a cavity defined by the ink ejection face, the film guide and the polymer film; and (c) guiding the polymer film through the transfer zone. The movement of the film in the transfer zone transfers the flooded ink onto the polymer film.

  • Patent number: 7832831
    Abstract: A printer includes a recording head having a nozzle that ejects ink and a suction pump that draws the ink through the nozzle. A valve unit and a filter are arranged in a passage that supplies the ink to the recording head. A controller of the printer operates the suction pump to perform suction/suspension in which suction of the ink from the passage through the nozzle and suspension of the suction are alternately repeated with the valve unit maintained in a closed state, thus promoting joining of bubbles on the filter. The controller then operates to open the valve unit to drain the joint bubbles from the filter, together with the ink, using negative pressure accumulated in the passage.
