摘要： After an ink-jet recording head with a plurality of discharging portions arranged is main-scanned in a direction perpendicular to the direction of the discharging portion arrangement to record a first image area, sub-scanning of the head is performed. Before the head is main-scanned to record a second image area, the sub-scanning is performed so that a few discharging portions on an upper edge portion of the head in second main-scanning overlap part of the first image area. Ink droplets land on pixels in the overlapping portion twice for each main-scanning, and image density of the pixels in the overlapping portion is controlled by the sum number of the landing ink droplets. This enables image density unevenness of image density, example, a "black stripe (banding)" or a "white stripe (banding)" in a boundary of an image area being recorded in each main-scanning, to be markedly reduced.

摘要： An ink-jet printing apparatus performs a printing process by discharging ink from color ink heads and treatment liquid from a liquid head for making the ink insoluble or coherent. The printing apparatus has the minimum amount of memory required to eject the treatment liquid as far as possible and performs excellent printing. For discharge data of one scanning performance of the color ink heads, the apparatus has only memories for each color ink head. Discharge data for the treatment liquid is formed by a treatment liquid discharge data creating portion based on the data stored in the memories upon switched by data-switching portion. Then the discharge data for the liquid head is supplied to the head after being stored in a buffer as much as the number of orifices of the head.

摘要： A data control apparatus is structured to execute complementary recording on one pixel array by dividing the scans of a recording head into four. In a nozzle context memory, the nozzle context data, which can be updated, are stored as control data to determine discharge or non-discharge of ink from discharge ports. In an operational circuit, the nozzle context data and image data are processed operationally, thus outputting drive data for the recording head. The data that indicates ink discharge in one pixel array are sequentially assigned to recording data per scan appropriately by use of the nozzle context data and the operational circuit. With the structure thus arranged, it is possible to implement making the capacity of memory smaller for use of data to control recording or non-recording, and also, to execute an intermittent recording by controlling recording or non-recording as required.

摘要： A recording apparatus records at a higher resolution than the resolution of input image data. A half toning processor performs a halftoning process at each pixel of the input image to get multi level data from the input image data. A data producer produces pattern data corresponding to the pixel of the input image based on the multi level data. Data for a plurality of different patterns is produced for at least one value of the multi level data.

摘要： In an ink jet printer, formation time of processing for generating data for providing a treatment liquid for improving fixing or water resistance of an ink by insolubilizing or coagulating a color material in the ink is reduced. For this purpose, to perform HV conversion for raster data for image data related to printing, processing for temporarily storing image data and processing of rewriting the HV conversion result are performed in a same sequence. For example, a treatment liquid data formation register having the same structure as an HV conversion register is provided. This register is masked to a pattern according to a treatment liquid composition on a printing medium and is made corresponding to data bits of the HV conversion register. Print data accessed by the HV conversion register is located in relation to the access, thereby forming the treatment liquid data simultaneously.
