    摘要: A printing method capable of printing a high-quality image at a high speed and low cost and a corresponding printing apparatus are disclosed. In this printing apparatus, a shading-corrected mask pattern for multipass printing control in consideration of the characteristics of each printing element of a printhead is generated. The size of the mask pattern in the conveyance direction of the printing medium is set to be an integer multiple of the conveyance amount of the printing medium per scanning of the printhead. Image data masked using the mask pattern is transferred to the printhead and printed. Alternatively, the conveyance-direction size of the mask pattern for masking print data in accordance with each pass printing of multipass printing is set to be equivalent to the number of nozzles of an ink-jet printhead having a plurality of nozzles arrayed in the conveyance direction of the printing medium, and the mask pattern is dividedly used for each pass printing. Any error of the position of a dot printed on the printing medium by an ink droplet discharged from each nozzle is detected in units of nozzles. Printing may be performed using a mask pattern generated such that a printing element with a small error is frequently used in accordance with the detection result, or performed such that the positions of print data are exchanged.

    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.

    摘要: A contamination of a printing medium caused by ink mist or the like is suppressed, which may scatter or float in an apparatus when margin-less printing is carried out in an ink jet printer. When margin-less printing for an edge of a printing medium P is performed, a predetermined edge area {circle over (1)} is printed using a smaller number of ejection openings during one scanning operation than that used for other areas {circle over (2)} and {circle over (3)}, while taking transportation errors relating to this end into consideration. This reduces the amount of ink mist resulting from ink ejected out of the edge of the printing medium during one scanning operation.
