摘要： An ink jet printing apparatus is provided which is capable of producing an image with a good balance between image quality and printing speed, without unduly shortening a longevity of a print head, even when an odd-numbered-pass bidirectional printing is performed. To this end, during a bidirectional multi-pass printing with a relatively small number of passes, a stepping mask is used to eliminate image problems caused by a difference in print permitted ratio between forward scan and backward scan. During a bidirectional multi-pass printing with a relatively large number of passes, a flat mask is used to give priority to suppressing density unevenness resulting from nozzle characteristic variations. As a result, the printing apparatus as a whole can produce an image with a good balance between image quality and printing speed, without unduly shortening a longevity of the print head.

摘要： An ink jet printing apparatus and an ink jet printing method are provided which are capable of minimizing image impairments caused by a bias of satellite positions even when an odd-numbered-pass bidirectional multi-pass printing is performed. To this end, in an odd-numbered-pass bidirectional printing, a mask pattern, in which print permitted pixels and print non-permitted pixels are arranged such a way that a percentage of pixels in which predetermined two inks are permitted to be printed by scans in different directions is higher than a percentage of pixels in which the predetermined two inks are permitted to be printed by scans in the same directions, is used. This increases the probability of satellites of the two types of the inks printed in the same pixels being printed on both sides of main dots, thus allowing a uniform image to be produced even by an odd-numbered-pass bidirectional printing.

摘要： According to this invention, an inkjet printing apparatus having an arrangement for detecting an amount of remaining ink in an ink tank starts a printing operation in a short time immediately after power-on. If an operation in preceding use is ended without any error at the time of power-off, and no error has occurred even at the time of power-on, the inkjet printing apparatus of this invention starts the printing operation without executing the operation of detecting the amount of remaining ink in the ink tank after power-on.

摘要： In the ink-jet printing apparatus, the influence of displacements of printing positions caused by the excessive conveyance of a printing medium to the resultant image when the rear end of the printing medium exits from a nip portion between the roller pair in a conveying mechanism. More specifically, in the printing operation for the rear end portion of the printing medium in which the printing medium exits from the roller pair, the guide shaft for supporting the carriage is lifted at a position wherein a head-medium distance is changed to widen a distance between the printing had and the printing medium (S402). Thereby, the displacement of the landing position caused by the excessive conveyance of the printing medium is inconspicuous because of the variations of the landing positions due to the widening of the head-medium distance.

摘要： There is provided an inkjet printing apparatus which executes a proper recovery operation in accordance with the demounting time period of an ink tank and information of the ink tank. In the inkjet printing apparatus of this invention, the demounting time period and information of the ink tank are used as parameters for determining the condition of a recovery operation after the ink tank is once demounted and thereafter mounted again. Since recovery is done in consideration of the degrees of ink evaporation and an increase in viscosity, wasteful ink consumption can be suppressed while a necessary recovery operation is performed.

摘要： In a print head having arrays of large nozzles and small nozzles with different ink ejection volumes that are connected to a common ink chamber, the preliminary ejection operation is performed 29,000 times first on only the large nozzles at an ejection frequency of 10 kHz to discharge viscous or mixed color ink from ink chambers. After the preliminary ejection operation of the large nozzles is finished, only the small nozzles are made to perform the preliminary ejection operation 2,000 times at an ejection frequency of 10 kHz. Reducing the number of preliminary ejections from the small nozzles in this manner can minimize the generation of stray mist. Further, by performing the preliminary ejection operation on the large nozzles first, it is possible to discharge enough viscous ink from the ink chamber.

摘要： An ink jet print apparatus having a plurality of double-sided printing mode (e.g., automatic double-sided printing mode and manual double-sided printing mode) is provided, which produces a sufficient image quality whichever mode is executed. For this purpose, image data to be printed is converted into print image data usable by the printing apparatus in a way that matches a selected one of multiple print medium transport paths. This minimizes a curling problem due to variations in transport processes, image quality variations caused by an ink fixing problem and adverse effects on the printing apparatus and ensures a stable printing whichever transport path is used for printing.

摘要： In a line-head type inkjet printing apparatus that ejects a plurality of types of inks, an inkjet printing apparatus is provided in which the change of its ejection properties different depending on the type of ink is prevented from occurring. The line-head type printing apparatus includes an acquisition unit that counts the ejection number of liquid from each of print heads in each of a plurality of print heads. Furthermore, the printing apparatus compares the ejection number of liquid from each of the print heads counted by the acquisition unit with a threshold value set for each of the print heads. The printing apparatus includes a change unit that can move a holder in the main scanning direction when the counted ejection number of liquid exceeds the threshold value set for the print head.
