摘要： An inkjet printing apparatus prints by scanning an inkjet printhead for discharging ink and a printing medium relative to each other. The printhead includes a first nozzle group used to print a dot having a first density, and a second nozzle group used to print a dot having a second density. The inkjet printing apparatus has a first printing mode in which only one of the first and second nozzle groups is used during one printing scan, and a second printing mode in which the first and second nozzle groups are driven at different timings during one printing scan. In this inkjet printing apparatus, a pattern for adjusting the relative printing positions of the nozzle rows in the first printing mode is printed. From this pattern, set values of relative printing positions in the first printing mode are specified. On the basis of the specified set values, set values of the relative printing positions of the nozzle rows in the second printing mode are determined.

摘要： This invention reduces an unprinted stripe occurred by edge deviation of a printhead. An inkjet printing apparatus according to this invention can execute a first printing mode in which an image is printed by scanning the printhead in a first region on the printing medium N times and scanning the printhead in a second region adjacent to the first region (N+1) times, and a second mode in which an image is printed by scanning the printhead in the first region M times and scanning the printhead in the second region (M+1) times. The width, in the conveyance direction of the printing medium, of the second region printed in the second printing mode is narrower than the width, in the conveyance direction of the printing medium, of the second region printed in the first printing mode.

摘要： When an image representing positional information, formed with black spot pattern and the other image formed with color inks including cyan, magenta, and yellow are recorded on the same recording medium, the gradient of color data is corrected during data preparation of colors used for recording the image other than the black spot pattern, according to the duty of the black spot pattern. Thus, even if the other image is recorded to overlap with the black spot pattern, color changes of the image can be prevented to produce a high-quality image.

摘要： To achieve high-quality printing by controlling an ink-travelling direction by an electrostatic force so that the ink can be accurately applied on a printing medium, the ink is landed on a desired position of the printing medium effectively without disturbing the ink ejection, independent of a difference in the thickness of the printing medium. An electric field between a printing head and the printing medium is generated by applying a voltage to a platen of conductive material positioned immediately below the printing medium. At this point, the voltage applied to the platen is adjusted so that the electric field of a preferable intensity can be generated on a face of the printing head where ejection openings are formed irrespective of the thickness of the printing medium.

摘要： One pixel is sub-divided on the basis of ejection ports. Pixel pattern are provided at respective quantization levels, each of which are defined using dots having different sizes. Image data is processed using a pixel pattern selected according to the type of printing medium and image quality to be achieved, and printing is performed using the image data. Only ejection ports ejecting ink droplets in the same size are driven at the same timing for ejection.

摘要： A printing apparatus receives block size information of a block which is generated on the basis of the performance of a host apparatus for a print buffer for storing print data of each block and serves as a storage unit in the print buffer. Print data generated based on the performance of the host apparatus for each block corresponding to the received block size information is stored in the print buffer. The CPU in the printing apparatus controls printing by the printhead on the basis of the print data stored in the print buffer.

摘要： The present invention provides an ink jet recording apparatus capable of recording high-quality images in which not only color shading caused in the process of reciprocating recording is prevented, but also bleeding between colors inherent in a multi-pass recording method is reduced. The position of the top of ejection orifices in a second ejection orifice row for ejecting color ink is spaced a length away from a first ejection orifice row for ejecting black ink. The length is determined according to values m, n and such a condition that the value a makes (m+a) an even number. Under the circumstances, recording is performed by reciprocating scanning, which makes differences in recording time between colors equal to each other.
