摘要： The sequence of the acquisition of a correction value of a conveying error depending on the eccentricity of the conveying roller (correction value for eccentricity) and the acquisition of a correction value of a conveying error depending on the outer diameter of the roller (correction value for outer diameter) is considered to acquire a precise correction value for outer diameter. A test pattern to acquire the correction values for eccentricity and for outer diameter is formed with an area exceeds the area corresponding to an integer multiple of the circumferential length of the roller. The correction value for eccentricity and that for outer diameter are acquired in this sequence. The fluctuation in the conveying error is reduced by the application of the correction value for eccentricity, and the influence of the excess area is made smaller before the correction value for outer diameter is acquired by averaging the conveying errors.

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.

摘要： The first print data indicating the discharging amounts of color and clear inks is generated in correspondence with an image to be printed with the color and clear inks. The second print data for designating a region for expressing decoration is generated. The discharging amount of the clear ink in the region for expressing decoration in the first print data is changed based on the second print data. Printing is done by scanning a printhead a plurality of number of times based on the changed first print data to execute the print scan of the clear ink after that of the color ink.

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： 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.
