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： In an image processing method, on the basis of input image data with respect to a target pixel, independent multi-level data (g0, g1) corresponding to respective plural species of dots which are different in at least one of a density and a diameter are generated, and then data (O0, O1) relating to an amount of generation of the dots with respect to the target pixel are generated on the basis of a relationship between the generated independent multi-level data (g0, g1) corresponding to the plural species of dots. The image processing method is effective in performing design having a high degree of flexibility in proper use of a relatively high power dot (high density dot or large dot) and a relatively low power dot (low density dot or small dot) and can realize obviation or alleviation of an occurrence of granulation or an apparent frame caused due to the relatively high power dot.

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 use amount of clear ink is set to minimize the hue difference Δθs−d from each of the colors corresponding to input signal values. The use amount of the clear ink to provide the minimum hue difference Δθs−d is varied depending on the use amount of color ink used for the color corresponding to the input signal value. A color conversion table having output values of the use amount and ink color data corresponding to the use amount is set. The color conversion in such a relationship is performed, whereby the bronzing color is recognized as a color close to the print color. As a result, undesired bronzing is lessened, so that degradation in image quality can be suppressed.

摘要： In the present invention, a conveying operation of a recording medium is controlled on the basis of a first correction value and a second correction value. The first correction value is used for correcting a conveying amount when the recording medium disengages from a first conveying roller, and the second correction value is used for correcting the phase of the first conveying roller and a second conveying roller when the recording medium disengages from the first conveying roller before the recording medium is nipped by the first conveying roller.
