Recording apparatus and a recording method

A recording apparatus for ejecting an ink on a recording medium, by using a recording head provided with an ejection portion for ejecting the ink, to perform recording on the recording medium, said recording apparatus comprising:

• scan means for scanning the recording head over the recording medium in a predetermined direction;
• obtaining means for obtaining discrepancy information based on a deviation of a distance from the ejection portion of the recording head to the opposing recording medium, in a scan region of the recording head;
• and
• control means for controlling an ink ejection timing of the recording head according to the discrepancy information.

A recording apparatus for ejecting an ink onto a recording medium, by using a recording head provided with an ejection portion for ejecting the ink, to perform recording on the recording medium, said recording apparatus comprising:

• scan means for scanning the recording head in a predetermined direction;
• control means for ejecting the ink from the recording head to perform recording as the recording head is scanned by said scan means;
• and
• correction means for controlling an ejection timing of the ink,
• wherein said correction means corrects the ejection timing such that the recording head ejects the ink in accordance with discrepancy information regarding a deviation of a paper-nozzle distance from a reference value, the paper-nozzle distance representing a distance from the ejection portion of the recording head to the recording medium.

A recording method of ejecting an ink onto a recording medium, by using a recording head provided with an ejection portion for ejecting the ink, to perform recording on the recording medium, said recording method comprising the steps of:

• a scan step of scanning the recording head in a predetermined direction;
• and
• a recording step of injecting the ink from the recording head to preform recording as the recording head is scanned,
• wherein an ejection timing is corrected in said recording step such that the recording head ejects the ink in accordance with discrepancy information regarding a deviation of a paper-nozzle distance from a reference value, the paper-nozzle distance representing a distance from the ejection portion of the recording head to the recording medium.
