摘要： The first printing mode improves gloss uniformity by setting the colorless ink discharge amount to be equal to or smaller than a reference value A at a dark image portion in input image data, and performing normal discharge printing in which printing with a colorless ink starts before completion of printing with a color ink (FIG. 11C). The second printing mode implements a wide color reproductive range by setting the colorless ink discharge amount to be larger than A at the dark image portion, and performing post-discharge printing in which discharge of the colorless ink starts after completion of printing with the color ink (FIG. 11D).

摘要： In a printing apparatus which prints an image on a printing medium by alternately performing printing of an image on the printing medium by using a printing unit and conveyance of the printing medium relative to the printing unit, the conveyance amount in conveyance is corrected by using first and second parameters for correcting the conveyance amount in accordance with different factors. This makes it possible to correct the conveyance amount in accordance with the deviation of the printing position due to the different factors.

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 around (1)} is printed using a smaller number of ejection openings during one scanning operation than that used for other areas {circle around (2)} and {circle around (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.

摘要： When recording a gradation pixel by performing pseudo-halftone processing, the occurrence of unevenness in the density in the recorded image is suppressed. For that purpose, when recording a pseudo-halftone image using dot patterns, a dot-pattern table storing a plurality of different dot patterns is provided for each gradation value. One dot-pattern table is selected from N dot-pattern tables based on gradation-value information for each pixel. One dot pattern is selected from the selected dot-pattern table, based on position information indicated by the pixel, and recording is performed using the selected dot pattern. It is thereby possible to prevent the concentrated use of a particular nozzle of a recording head, and suppress the occurrence of unevenness in the density due to characteristics of the specific nozzle.

摘要： The present invention aims to obtain preferable correction values to correct the conveying error of a conveying roller in accordance with the size of a printing medium, even when the conveying error caused by the eccentricity of the roller varies from a point to another in the longitudinal direction of a roller, depending on the amount and the state of eccentricity of the roller. To achieve this object, correction values are acquired using the whole part of or only a part of plural test patterns formed in the longitudinal direction of the roller. The correction values thus acquired correspond to the respective zones where the test patterns are formed.

摘要： High image quality is maintained even on front and rear ends of a printing medium where deterioration in the image quality is more likely to occur due to reduction in conveyance accuracy of the printing medium. In printing on the front and rear ends, the printing medium being not supported by both conveying means respectively placed upstream and downstream of a printing point in a printing medium conveying direction, a print swath of a printing head and the amount of conveying a printing medium are reduced. Moreover, the reducing print swath and the reducing conveyance amount are designed to be decreased in the cases of selecting a printing medium for high-quality printing as well as a monochrome print mode where image distortion caused by deviation of ink-landing positions is more noticeable due to a small number of colors of ink to be used and low coverage thereof.
