摘要： PROBLEM TO BE SOLVED: To provide an inkjet recording apparatus which can maintain normal delivery even though a recording medium skews, and can prevent the deterioration of recording.SOLUTION: The inkjet recording apparatus calculates a skew amount of the recording medium based on recording images 701-704 and decides a nozzle width used for recording in advance (for 8 nozzles). The apparatus decides nozzles (nozzles 11-18) used for preliminarily delivery based on the decided nozzle width and preliminarily delivery is performed with the decided nozzles. Thereby, the inkjet apparatus is obtained which can maintain normal delivery even though the recording medium skews, and can prevent the deterioration of recording.

摘要： PROBLEM TO BE SOLVED: To provide a recorder which certainly and stably suppresses the variation of density in a unit region and outputs an image without density variation even if a recording position shifts between two or more recording scans in a case of a multipath recording, and also to provide a recording method.
SOLUTION: Image data of many gradations is converted into two or more dot arrangement patterns which have defined the record or non-record of dot to each area according to the level. After that, these two or more dot arrangement patterns are repeatedly recorded on a recording medium by a recording scan with different recording head. In this case, two or more dot arrangement patterns are determined so that the change of proportion of overlapping area may decrease as compared with the case of dots being arranged exclusively even in a case where these two or more dot arrangement patterns are shifted each other.

摘要： PROBLEM TO BE SOLVED: To provide an inkjet recorder that can record an alignment mark having a good precision for locating a position of an analysis pattern.SOLUTION: The inkjet recorder performs recording by using a recording head having, arranged thereon, a plurality of nozzles for ejecting ink. The inkjet recorder includes a moving means that moves the recording head relative to a recording medium, and a recording control means that records an inspection pattern having an analysis pattern and an alignment mark as a reference for identifying a position of the analysis pattern by discharging ink from the recording head while moving the recording head relative to the recording medium by the moving means. The alignment mark is formed of a plurality of pixels arranged in an arrangement direction of the plurality of nozzles and arranged in a direction perpendicular to the arrangement direction. In the plurality of pixels, pixels adjacent in a direction perpendicular to the arrangement direction of the plurality of nozzles are not recorded by ink ejected from an identical nozzle.

摘要： PROBLEM TO BE SOLVED: To form image data which reduces connection stripes produced, since dots are formed while shifting in the carrying direction of a recording medium or nozzle arrangement direction from the regular position in an image forming apparatus.
SOLUTION: The image forming apparatus corrects image data to be quantized using the data after quantization of pixel upper by one raster as a correction value before quantizing the image data of pixels P1 to Pn. Namely, the quantization result of the pixel upper by one raster of the pixel P1 is a black pixel (pixel recording a dot), and the quantization result of the pixel upper by one raster of the pixel P2 is a white pixel (pixel not recording a dot). A dot is made to be recorded also on the pixel P1 by the correction for image data of the pixel P1 whose upper side is a black pixel. On the contrary, the dot is not made to be recorded in the pixel P2 in the correction for image data of the pixel P2 whose upper side is a white pixel.

摘要翻译：要解决的问题：为了形成减少连接条纹的图像数据，因为在图像形成装置中沿着记录介质的传送方向或喷嘴排列方向从正常位置移动时形成点。解决方案：图像形成装置在量化像素P1至Pn的图像数据之前，使用上述一个光栅的像素的量化之后的数据作为校正值来校正要量化的图像数据。也就是说，像素P1的上一个光栅的像素的量化结果是黑色像素（记录点的像素），并且像素P2的上一个光栅的像素的量化结果是白色像素（不记录像素一个点）。通过对上侧是黑色像素的像素P1的图像数据的校正，也将点记录在像素P1上。相反，在上侧是白色像素的像素P2的图像数据的校正中，不将点记录在像素P2中。版权所有（C）2011，JPO＆INPIT
