摘要： When bidirectional multi-pass printing is carried out by use of a printing head having an inclination, even if a bidirectional printing is somewhat displaced, an inclination of a printing position is corrected in a state where “band unevenness” is suppressed as much as possible. In order to realize the correction described above, a division number B for dividing a plurality of printing elements into a plurality of blocks, and a timing at which each of the blocks is driven, are set on the bases of inclination information on the printing head and the number of multi-passes. Thus, even if the bidirectional printing is displaced, printing widths are equally increased or reduced in the respective regions. Consequently, it is made possible to avoid the “band unevenness” which is caused by differences in the printing width among the regions.

摘要： An inkjet recording apparatus includes a recording head having a nozzle array of plural nozzles capable of discharging ink. The inkjet recording apparatus performs a scanning/recording operation for forming an image on a recording medium by shifting the recording head in a main scanning direction. The inkjet recording apparatus repeatedly perform the scanning/recording operation and a recording medium conveying operation. The inkjet recording apparatus sets a recording position correction amount for each section of the nozzle array based on information relating to the inclination, so that a recording position correction amount in a forward scanning operation is different from a recording position correction amount in a backward scanning operation.

摘要： When conveying tables for conveying the printing medium are selected to perform interlace printing, the occurrence of unevenness in an image which results from switching of the tables is prevented. It is determined whether a phase of the conveying table is a transfer inhibition phase in transfer to a printing area. In the case of the transfer inhibition phase, the switching is not made to a new table, but the previously used table is used. Thus, the switching can be made to a conveying table so as not to make a shift amount +1/2N or −1/N continue. Consequently, it is possible to prevent the occurrence of unevenness in an image which is caused by 1/N deviation of a printing position in a sub-scanning direction with regard to print data at the time of transfer from a rear end area to the normal area or the normal area to the rear end area.

摘要： A print buffer for storing recording data is divided into a plurality of segments and the amount of recording data causing a recording head to perform a recording operation is counted on a segment-by-segment basis. A recording medium is compared to the print buffer with respect to a scanning direction of the recording head and segments not corresponding to the inside of the recording medium are selected from the plurality of segments. The amount of recording data included in the selected segments and causing a recording operation to occur is counted and added up to estimate the amount of ink ejected outside the recording medium.
