Inkjet recording method
First Claim
Patent Images
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, 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.

6. An inkjet recording method using a line-array inkjet head, comprising:
-
setting ink ejection frequencies different for respective ink ejection holes disposed in an array; and
ejecting inks onto a plate-shaped recording medium at the different ink ejection frequencies from the ink ejection holes to perform recording, 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, 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, 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, and the recording dot size is substantially proportional to the relative peripheral rotating speed in the position of each of the ink ejection holes. - View Dependent Claims (7)

8. An inkjet printer printing on a recording medium using a line-array inkjet head, comprising:
-
the ink jet head with a plurality of nozzles disposed in an array;
a plate-shaped recording medium receiving ink drops ejected from said plurality of nozzles; and
a controller controlling ejection frequencies for the nozzles, wherein the ejection frequency for said ejection nozzles differ depending on a relative peripheral rotating speed in a position of each of said plurality of ejection nozzles, and 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. - View Dependent Claims (9, 10, 11, 12)
