摘要： According to the present invention, an adjustment value applicable to the adjustment of a printing position is obtainable by reading a printing position adjustment pattern printed on a printing medium without requiring the manual operation by the operator. Furthermore, the printing position can be optimally adjusted by accurately scanning the printing position adjustment pattern. For this purpose, an optical sensor is located in the vicinity of the printing head, and the optical sensor is situated near a predetermined position side. The predetermined position side is a pinch roller side where a large restrictive force acts to the printing medium with the printing position adjustment pattern printed thereon.

摘要： A printing apparatus and a print position aligning method are provided which can execute a dot position adjust value calculation mode normally and smoothly without requiring the user to make decisions or adjustments. A test pattern to check the width of a print medium is printed and is detected by an optical sensor to decide whether or not a dot position adjustment pattern can be printed. Before the dot position adjustment pattern is printed, a decision is made as to whether the print medium supplied is appropriate or not. If the print medium supplied is smaller than a size specified for the dot position adjust value calculation processing, the print medium is discharged without being printed with the dot position adjustment pattern. This eliminates a possibility of a wasteful consumption of print mediums and of contaminating the interior of the printing apparatus.

摘要： A liquid ejection head according to the present invention includes a single liquid supplying port to which a liquid is supplied, a plurality of liquid supplying passages having one end in communication with the liquid supplying port, a plurality of common liquid chambers that are in communication with the other ends of the liquid supplying passages, respectively, and a plurality of ejection port groups which are in communication with the common liquid chambers via liquid channels and from which liquid droplets are ejected. A cross sectional area or length of the liquid supplying passage in communication with the ejection port group having a larger sum of opening areas of the ejection ports is set smaller than that of the liquid supplying passage that is in communication with the ejection port group having a smaller sum of opening areas of the ejection ports.

摘要： If print agents used are detected by an optical sensor at different sensitivities, the preset invention enables the easy setting of adjustment values for print positions resulting from these print agents. To accomplish this object, for example, the present invention substitutes and sets adjustment values for print positions resulting from cyan, light cyan, or black ink, corresponding to a high detection sensitivity, for adjustment values for print positions resulting from a light magenta, yellow, or magenta ink, corresponding to a low detection sensitivity.

摘要： An inkjet recording apparatus suppresses defective ejection while reducing a consumed ink amount. In the apparatus, a cap-open period, during which a cap member does not cap ejection ports of a recording head of the apparatus, is measured, and a recovery operation executed by a recovery unit is controlled based on a cumulated cap-open period. With the above arrangement, there can be solved a problem that the ink ejecting state of the recording head is deteriorated depending on a recording operation because a cap-open state, in which the cap member does not cap the ejection ports of the recording head, continues while the inkjet recording apparatus executes the recording operation, thereby the reliability of the inkjet recording apparatus can be improved.

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： An ink-jet printing apparatus and an ink-jet printing method allow the printing of an image with high quality without causing a change in ink color formed on the printing medium while keeping the printing conditions constant regardless of changing of the number of nozzles to be printed and the amount of transferring of the printing medium. This printing is performed, for example, by restricting use of the number of nozzles, which belong to a nozzle row located on an upstream side in the sub-scan direction, before changing the amount of transferring of the printing medium; and restricting use of the number of nozzles, which belong to the nozzle rows located on a downstream side in the sub-scan direction, after changing the amount of transferring of the printing medium.
