20110227982 | RECORDING APPARATUS AND RECORDING METHOD - In a mask pattern used in effecting multi-path recording, (A) a recording permission ratio in each pixel row of a non-boundary area of a first pattern portion corresponding to a first nozzle block is substantially a first value, and a recording permission ratio in each pixel row of a non-boundary area of a second pattern portion corresponding to a second nozzle block adjacent the first nozzle block is substantially a second value, and (B) in a boundary area including a boundary between the first pattern portion and the second pattern portion, the recording permission ratio in each pixel row is between the first value and the second value, and the recording permission ratios in each pixel line are made different depending on a position with respect to a scanning direction. By this, in addition to reducing effects of an in-band unevenness and an inter-band unevenness by (A), a reducing effect of a connecting stripe can be provided by (B). | 09-22-2011 |

In-band and inter-band unevenness and a connecting stripe are reduced by (A) and (B), respectively. | 04-04-2013 |
20140354716 | INK JET PRINTING APPARATUS AND METHOD FOR ESTIMATING MOISTURE CONTENT OF PRINT SHEET - In an ink jet printing apparatus of the present invention, a moisture content of a print sheet is estimated without decreasing productivity of the printing apparatus and appropriate conditions of printing operation in the subsequent printing process are specified. More specifically, by measuring a change in thickness of the print sheet after printing, a state of moisture content is estimated. Estimating a state of moisture content allows determination of appropriate conditions of printing operation such as a minimum drying time required for printing a high-quality image on various types of print sheets such as print coated paper or coated paper. | 12-04-2014 |
20150109365 | INK, INK CARTRIDGE, AND IMAGE-RECORDING METHOD - Provided is an ink containing a self-dispersible pigment, an acrylic resin particle, a surfactant, a water-soluble organic solvent, and water. The surfactant includes a fluorinated surfactant represented by Formula (1) and having an HLB value determined by a Griffin method of 11 or less. The water-soluble organic solvent includes at least one water-soluble organic solvent selected from a specific group, and the total content of the water-soluble organic solvents of the specific group is 4 times or more the total content of the water-soluble organic solvents other than the solvents of the specific group. The total content of the self-dispersible pigment and the acrylic resin particle is 10% by mass or less based on the total mass of the ink. | 04-23-2015 |
20150109384 | INK, INK CARTRIDGE, AND IMAGE-RECORDING METHOD - Provided is an ink containing a self-dispersible pigment, a polyurethane polymer particle, a surfactant, a water-soluble organic solvent, and water. The surfactant includes a fluorinated surfactant represented by Formula (1) and having an HLB value determined by a Griffin method of 11 or less. The water-soluble organic solvent includes at least one water-soluble organic solvent selected from a specific group, and the total content of the water-soluble organic solvents of the specific group is higher than the total content of the water-soluble organic solvents other than the solvents of the specific group. | 04-23-2015 |
20150184007 | INK, INK CARTRIDGE, AND IMAGE-RECORDING METHOD - An ink contains a pigment dispersed with polymer, a surfactant, a water-soluble organic solvent, and water. The mass ratio of a content of the pigment to a content of the polymer in the ink is more than 3. The surfactant includes a fluorinated surfactant which is represented by Formula (1) and which has an HLB of 11 or less as determined by a Griffin method. The water-soluble organic solvent includes at least one selected from specific Group A. The total content of the water-soluble organic solvents of the Group-A in the ink is larger than the total content of water-soluble organic solvents other than the water-soluble organic solvents of Group A in the ink. | 07-02-2015 |
