Recording apparatus and pattern forming method

摘要

A recording apparatus to record an image to a recording medium includes a recording head having nozzles arranged in a predetermined direction in a nozzle array, scanning, recording control, obtaining, determining, and adjusting units. The scanning unit scans the recording head to the recording medium in a crossing direction. The recording control unit causes the recording head to record an adjusting pattern and a detecting pattern by discharging ink from a nozzle group. The obtaining unit obtains an information regarding number of defective discharge nozzles in the nozzle group based on the detecting pattern. The determining unit determines an adjusting value based on the recorded adjusting pattern where the indicated number is smaller than a threshold value, and not based on the adjusting pattern where the indicated number is larger than the threshold value. The adjusting unit adjusts the recording head recording position based on the determined adjusting value.

主权项

1. A recording apparatus to record an image to a recording medium, the recording apparatus comprising:
a recording head having a nozzle array in which a plurality of nozzles for discharging ink is arranged in a predetermined direction; a scanning unit configured to scan the recording head to the recording medium relatively in a crossing direction which crosses the predetermined direction; a recording control unit configured to cause the recording head to record an adjusting pattern for adjusting a recording position of the recording head to the recording medium and a detecting pattern for detecting nozzle of defective discharge on a recording medium by discharging ink from a nozzle group which is formed by a part of the plurality of nozzles in the nozzle array; an obtaining unit configured to obtain an information regarding number of nozzles of defective discharge in the nozzle group based on the detecting pattern; a determining unit configured to determine an adjusting value (i) based on the adjusting pattern recorded by the recording head in a case where the number indicated by the information obtained by the obtaining unit is smaller than a threshold value, and (ii) not based on the adjusting pattern recorded by the recording head in a case where the number indicated by the information obtained by the obtaining unit is larger than the threshold value; and an adjusting unit configured to adjust the recording position of the recording head based on the adjusting value determined by the determining unit.
