Claims

A recording unit that scans a recording head including a recording element that ejects ink in response to application of a drive pulse to record dots on a recording medium;
Drive pulse changing means capable of adjusting the amount of ejected ink by changing the drive pulse;
An ejection timing changing means capable of adjusting a recording position of the dots by changing an ink ejection timing from the recording head;
Have
The ink jet recording apparatus, wherein the discharge timing changing means changes the ink discharge timing from the recording head so that the dot recording position does not change before and after the drive pulse is changed by the drive pulse changing means. .

2. The drive pulse changing unit according to claim 1, wherein the drive pulse changing unit changes the drive pulse so that the amount of the ejected ink is kept constant regardless of the temperature of the recording head. Inkjet recording device.

An adjustment value acquisition means for acquiring an ink ejection timing adjustment value for correcting a shift in the dot recording position;
The ink jet recording apparatus according to claim 1, wherein the ink discharge timing changing unit further changes the ink discharge timing from the recording head based on the ink discharge timing adjustment value.

The recording head includes a first ejection port array in which the ejection timing changing unit changes the ink ejection timing, a larger amount of ink ejected than the first ejection port array, and the ejection timing changing unit changes the ink ejection timing. The inkjet recording apparatus according to claim 1, further comprising a second ejection port array that is not disposed.

The recording head includes a first ejection port array and a second ejection port array having a larger amount of ink ejected than the first ejection port array and a large number of types of drive pulses that can be changed by the ejection timing changing unit. The ink jet recording apparatus according to claim 1, wherein the ink jet recording apparatus is an ink jet recording apparatus.

In an inkjet recording apparatus that records dots on the recording medium by moving a recording head that ejects ink by applying a driving pulse relative to the recording medium.
Means for obtaining an adjustment value for determining a position at which the recording head records dots on the recording medium;
Means for selecting one drive pulse in accordance with at least one of the temperature of the recording head or the environmental temperature from a PWM table prepared with a plurality of types of the drive pulses;
Means for correcting the adjustment value in accordance with the type of drive pulse selected by the selection means;
Means for causing the recording head to perform recording using the selected drive pulse and the adjustment value corrected by the correction means;
An ink jet recording apparatus comprising:

A recording unit that scans a recording head including a recording element that ejects ink in response to application of a drive pulse to record dots on a recording medium;
Drive pulse selecting means for selecting one type of drive pulse from a plurality of types of drive pulses according to the temperature of the print head so that the amount of the ejected ink is constant regardless of the temperature of the print head; ,
A correction value corresponding to the selected drive pulse is used as a correction value for correcting the ink ejection timing from the print head in order to prevent the dot recording position from changing regardless of the plurality of types of drive pulses. Acquisition means for acquiring;
Control means for controlling the recording means to perform recording based on the selected drive pulse and the acquired correction value;
An ink jet recording apparatus comprising:

An inkjet recording method for recording dots on a recording medium by scanning a recording head provided with a recording element that discharges ink in response to application of a drive pulse,
A drive pulse changing step capable of adjusting the amount of ejected ink by changing the drive pulse;
An ejection timing changing step capable of adjusting the recording position of the dots by changing the ink ejection timing from the recording head; and
Have
In the ink jet recording method, in the ejection timing changing step, the ink ejection timing from the recording head is changed so that the dot recording position does not change before and after the drive pulse is changed.
