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.

摘要： While a conveying error of a roller depends on the eccentricity of the roller, the amount and the state of the eccentricity sometimes makes the roller have different conveying errors from one point in the longitudinal direction of the roller to another. There is provided a construction for obtaining a correction value that is suitable for the correction of the conveying error even in such a case as described above. To this end, plural test patterns are formed in the longitudinal direction of the roller. Then, a suitable correction value for correcting the conveying error that depends on the eccentricity of the roller is obtained on the basis of these test patterns.

摘要： There is provided an inkjet printing apparatus which can restrict each of coloring of reflected light and image clarity within an allowable range required in each of a color mode and a monochromatic mode in any of the modes to output an image with a high grade. For this end, a print duty of each of the first image improving liquid and the second image improving liquid is set in such a manner that a ratio of the print duty of the first image improving liquid having low penetratability to the print duty of the second image improving liquid having high penetratability is higher in the monochromatic mode than that in the color mode. Thereby, an appropriate ratio and an appropriate amount of appropriate kinds of the image improving liquids are applied to each of the color mode and the monochromatic mode.

摘要： A plurality of ejection portions are divided into groups, each containing at least one ejection portion, so that the suction-based recovery operation can be performed for each group independently. Since the number of ejection portions contained in each group differs, if an ink flow resistance varies among the different groups, simultaneous suction-based recovery operations can be done by using a common suction pump, without having to sequentially perform the suction-based recovery operations under an optimum pump driving condition. For this purpose, inner diameters of a plurality of ink discharge tubes running from a plurality of cap units, which cap a plurality of print head units having different numbers of ejection portions, to the common pump are differentiated. This allows different flows to be produced in different ink discharge systems, thus generating desirable ink flows for individual ink supply systems.

摘要： For a recording apparatus capable of supplying a plurality of different color inks to a plurality of recording element substrates, when a condition for performing maintenance on a first recording element substrate is met, it is determined whether or not to perform maintenance on a second recording element substrate according to how close the second recording element substrate is to meeting the condition. Since maintenance is performed on the first and second recording element substrates in such a manner, unnecessary maintenance operations will be prevented from being carried out multiple times within a short period of time. Accordingly, the total amount of time required for maintenance is reduced.

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： Performed is conveying-error correction in accordance with the kind and the number of rollers that are actually involved in the conveying of a printing medium. Each of the rollers that are potentially involved in the conveying of the printing medium has a unique amount of eccentricity, and may affect the quality of image to be printed in a peculiar manner. To address this problem, a surface of the printing medium is divided into areas according to the number and the combination of the rollers that are actually involved in the conveying. A pattern each is printed for each of the areas thus formed while the pattern enables the detection of the conveying error. A correction value to correct the conveying error is calculated using each of the patterns. The correction values thus obtained are reflected in the conveying of the printing medium.
