20090147039 | Curl Predicting Method and Liquid Discharge Device - A curl predicting method includes calculating liquid amount discharged to each of areas defined on a medium by a liquid discharge device for every area defined on the medium and predicting a curl state of the medium which is attributable to liquid discharged to the medium on the basis of a position of the area on the medium and the amount of the liquid discharged to the area. | 06-11-2009 |
20090244634 | Image Processing Device, Image Processing Method, and Image Processing Program - An image processing device includes a memory portion for storing an ejection amount conversion table showing a relationship between image data serving as reference and a fluid ejected from a fluid ejecting head for a predetermined number of pixels, and an ejection amount estimation unit which estimates an ejection amount of the fluid from input image data on the basis of the ejection amount conversion table stored in the memory portion. | 10-01-2009 |
20100177136 | LIQUID DISCHARGING APPARATUS AND METHOD FOR DETECTING MALFUNCTIONING NOZZLES ON THE BASIS OF IMAGE DATA - To shorten time for an abnormal discharge test and time for cleaning; and to reduce the amount of drain ink used at the time of the abnormal discharge test and the cleaning. A liquid drop discharging apparatus comprising: a plurality of nozzles that discharge liquid drops; a sensor that detects a malfunctioning nozzle at which abnormal discharge occurs when the liquid drop is supposed to be discharged therefrom; and a controller that determines whether the liquid drop is discharged or not from each of the nozzles on the basis of image data, the controller causing the sensor to detect the malfunctioning nozzle among the nozzles that are determined to discharge the liquid drops on the basis of the image data. | 07-15-2010 |
20110063349 | PRINTING APPARATUS AND PRINTING METHOD - A printing apparatus includes: a head unit that ejects ink; and a control unit that causes the head unit to eject ink. In the case where a first image and a second image that is adjacent to the first image are formed, the control unit forms a third image by causing ink to be ejected, in pixels within the second image at the boundary area between the first image and the second image, at an ejection amount that is greater than the amount of ink per unit pixel ejected in order to form the second image. | 03-17-2011 |
20110216114 | PRINTING APPARATUS AND METHOD OF CONTROLLING PRINTING APPARATUS - There is provided a printing apparatus includes a head having a slow-permeation-black-nozzle-group which discharges slow-permeation-black-ink, and an excessive-permeation-black-nozzle-group which are arranged at the same pitch as the slow-permeation-black-nozzle-group and are deviated from the slow-permeation-black-nozzle-group by ½ pitch in a sub scanning direction, and a control unit which controls scanning of the head in a main scanning direction and ink discharging through each group. In the printing apparatus, the control unit controls to perform printing in any one of a plurality of printing modes including a normal printing mode in which printing is performed such that slow-permeation-black-ink is discharged through the slow-permeation-black-nozzle-group while excessive-permeation-black-ink is not discharged through the excessive-permeation-black-nozzle-group, and a high-speed printing mode in which printing is performed such that slow-permeation-black-ink is discharged through the slow-permeation-black-nozzle-group and excessive-permeation-black-ink is discharged through the excessive-permeation-black-nozzle-group. | 09-08-2011 |
20120224005 | LIQUID EJECTION APPARATUS - There is provided a liquid ejection apparatus in which convection generated by a convection generation unit does not give an influence on an irradiation unit, ink can be heated and dried sufficiently, and bleeding can be suppressed from occurring. The liquid ejection apparatus includes a head unit which has a nozzle for ejecting liquid onto a recording medium, a carriage which makes the head unit relatively scan the recording medium, an infrared ray irradiation unit which is provided at a vertically upper side of the carriage in a scanning direction of the carriage and irradiates the recording medium with infrared rays, a convection generation unit which is provided at a vertically upper side of the carriage in the scanning direction of the carriage and generates convection on the recording medium, and a separation wall which is provided between the infrared ray irradiation unit and the convection generation unit. | 09-06-2012 |

20120075380 | INK SET AND INK JET RECORDING METHOD USING THE INK SET - An ink set used for an ink jet recording method, in which a reactive solution and a color ink composition are adhered to a recording medium to realize recording, contains a reactive solution containing a polyvalent metal salt, and a first color ink composition at least containing a coloring material, a sparingly water-soluble 1,2-alkanediol, a surfactant and water. | 03-29-2012 |
20130182057 | INK JET RECORDING METHOD AND RECORDING APPARATUS - An ink jet recording method includes using at least a first ink composition containing a color material and a second ink composition containing a resin as well as substantially not containing a color material, including: a first recording step recording the first ink composition onto a medium to be recorded; a second recording step recording the second ink composition onto the image; a second drying step of drying the image at a first temperature, which is performed during execution of the second recording step or thereafter; and a third drying step of drying the image at a second temperature which exceeds the first temperature after the second drying step; in which, the second ink composition does not substantially contain an aprotic polar solvent, and the heat deformation temperature of the resin exceeds the first temperature and is lower than the second temperature. | 07-18-2013 |
20130300797 | INK JET RECORDING METHOD, INK JET RECORDING APPARATUS, AND RECORDED MATTER - An ink jet recording method using ink selected from a group including (A) black ink containing black pigment, (B) mixed color black ink containing black and color pigments, and (C) color ink containing color pigment, in which an ink glossiness at 60° is increased in the order of black ink (A), mixed color black ink (B), and color ink (C), the target recording surface glossiness at 60° in a target recording medium is 40 or more, and at least one of the following is satisfied: (1) A black image is formed using at least a plurality of types of the color ink of (C) and a color image is formed using the color ink of (C), and (2) A black image is formed using the mixed color black ink of (B) and a color image is formed using the color ink of (C). | 11-14-2013 |
