| 20090080002 | INKJET RECORDING APPARATUS, IMAGE PROCESSING METHOD, STORAGE MEDIUM, PIGMENTED INK, AND RECORDED MATTER - A disclosed inkjet recording apparatus for performing recording by jetting a recording liquid onto a recording medium includes an image processing unit configured to obtain an output halftone level by performing halftone processing on input image data, to select a dot arrangement order according to the obtained output halftone level, and thereby to generate dot data where dots are arranged in a grid-like pattern. The disclosed inkjet recording apparatus is configured to use a pigmented ink as the recording liquid when the recording medium is a commercial printing paper, and to record the dots in a staggered arrangement where positions of the dots in odd/even-numbered columns or odd/even-numbered rows in the dot data are shifted in a sub-scanning direction or in a main-scanning direction. | 03-26-2009 |
| 20100141707 | IMAGING APPARATUS - An imaging apparatus is disclosed that includes plural heads that are arranged in a main scanning direction, the heads including plural nozzle arrays that are arranged in the main scanning direction and configured to discharge droplets of recording liquids in at least three different colors including a yellow recording liquid. At least two of the nozzle arrays that are configured to discharge the yellow recording liquid are separately arranged in at least two of the heads. At least two of the nozzle arrays that are configured to discharge a first recording liquid of the recording liquids in a first color other than yellow are arranged together in one of the heads. At least two of the nozzle arrays that are configured to discharge a second recording liquid of the recording liquids in a second color other than yellow are arranged together in one of the heads. | 06-10-2010 |
| 20100231631 | IMAGE PROCESSING METHOD, PROGRAM, IMAGE PROCESSING APPARATUS, IMAGE FORMING APPARATUS, IMAGE FORMING SYSTEM - An image forming method is disclosed in which an image is formed on commercial printing paper using a high penetration pigmented ink by performing image processing which makes use of dot patterns corresponding to an output halftone level. | 09-16-2010 |
| 20110273746 | IMAGE PROCESSING APPARATUS, IMAGE FORMING APPARATUS, AND IMAGE PROCESSING METHOD - A disclosed image processing apparatus performs an image processing operation to execute double-side printing on both sides of an image forming medium. The image processing apparatus forms a dot font including a dot pattern of a character in a character image that has undergone a halftone process using a predetermined coefficient for mitigating show-through when the double-side printing is performed; forms a correction dot for making a correction to reduce step-like irregularities along an outline portion of the character in the character image, which correction dot is formed based on an arrangement position, a color, and a dot size of the correction dot for reproducing a gradation that has undergone the halftone process using said predetermined coefficient; and combines the dot font and the correction dot. | 11-10-2011 |
