    摘要： The present invention provides a method of printing a high quality color image with no color variations at high speed. For this purpose, this invention arranges in a main scan direction a plurality of print heads that eject different color inks, and reciprocally moves each of the print heads to perform a multipass printing in which a print operation is executed in both the forward and backward passes. During the multipass printing, the print duties of the print heads are set by mask patterns. Each of the mask patterns divides the print duty setting area for each nozzle group of each head into subdivided areas, sets the print duties of the subdivided areas to values different from each other and sets the print duties of the print heads to different values.

    摘要： When an image is sensed by a digital camera, image additional information as image sensing conditions is stored together with the sensed image information. Also, information unique to that digital camera is stored together with the image additional information. The digital camera is connected to a printer by, e.g., an IEEE1394 I/F. The printer stores printing control information as various combinations of unique information such as its printing method, the types of ink, the paper, and the like, the print quality and the print speed, and the processing technique, such as masking. In response to a print instruction, the printer reads the image information and image additional information from the digital camera, and selects the printing control information in accordance with the read information and the set printing mode. The printer prints an image using the selected printing control information.

    摘要： By using an ink jet head, which has for each color two parallel columns of nozzles arranged side by side in the main scan direction and shifted from each other by one-half the pitch at which the nozzles are arranged in each column, odd-numbered rasters and even-numbered rasters making up an image are printed by the two nozzle columns. The registration between the odd- and even-numbered rasters is secured during the printing to produce an image with high print quality. For that purpose, the ink ejection timing between the two raster groups is shifted by a predetermined interval to form a plurality of adjustment patterns; the adjustment patterns printed are checked and, according to the check result, an adjustment value for the ink ejection timing between the two ink nozzle columns is entered, and the entered adjustment value is stored to be reflected on the actual printing operation. To facilitate the adjustment pattern check, the plurality of adjustment patterns have a dot distribution with a blue noise characteristic at a resolution at which the printing apparatus can print.
