Abstract

An inkjet recording method uses a line-array inkjet head, sets different ink ejection frequencies for respective ink ejection holes desposed in array and ejects ink onto a plate-shaped recording medium at the different ink ejection frequencies from the ink ejection holes to perform recording.

Claims

1. An inkjet recording method using a line-array inkjet head, comprising:

setting ink ejection frequencies different for respective ink ejection holes disposed in array; and

ejecting inks onto a plate-shaped recording medium at the different ink ejection frequencies from the ink ejection holes to perform recording.

2. An inkjet recording method according to claim 1, wherein:

the line-array inkjet head and the recording medium are relatively rotated about a straight line, as an axis of rotation, passing through one point on a straight line extending inclusively of the line-array, which is perpendicular to the recording medium; and

the recording is performed by ejecting an ink from each of the ink ejection holes at the ink ejection frequency substantially proportional to a relative peripheral rotating speed in a position of each of the ink ejection holes.

3. An inkjet recording method according to claim 2, wherein when performing the recording by ejecting the ink from each of the ink ejection holes, a recording dot size differs for each of the ink ejection holes.

4. An inkjet recording method according to claim 3, wherein the recording dot size is substantially proportional to the relative peripheral rotating speed in the position of each of the ink ejection holes.

5. An inkjet recording method according to claim 1, wherein the ink ejection frequency at which the ink is ejected from each of the ink ejection holes is changed in accordance with a content of the recording.

6. An inkjet recording method according to claim 2, wherein the ink ejection frequency at which the ink is ejected from each of the ink ejection holes is changed in accordance with a content of the recording.

7. An inkjet recording method according to claim 3, wherein the ink ejection frequency at which the ink is ejected from each of the ink ejection holes is changed in accordance with a content of the recording.

8. An inkjet recording method according to claim 4, wherein the ink ejection frequency at which the ink is ejected from each of the ink ejection holes is changed in accordance with a content of the recording.
