Abstract
The test image is formed in accordance with input data in which a plurality of recording elements selected every N (an integer of 1 or more) pieces in a projected recording element group is indicated as a first recording element and a recording element that is not selected as the first recording element is indicated as a second recording element, the input data allowing: a first-stage pattern to be formed in a recording area of the second recording element in accordance with a second input gradation value; a recording position in the second direction to be sequentially changed; and the first recording element and the second recording element to be sequentially switched to form a second-stage pattern to an (N+1)-th-stage pattern.
Claims21
A test image forming system that forms a test image on a recording medium by relatively moving a recording head and the recording medium in a first direction and a second direction orthogonal to the first direction, the test image forming system comprising:
- an input data acquiring unit that acquires input data in which, N representing an integer of 1 or more, a plurality of recording elements selected every N pieces in a projected recording element group of a plurality of recording elements provided in the recording head, projected in the first direction, is indicated as a first recording element and a recording element that is not selected as the first recording element is indicated as a second recording element, the input data allowing:
- a first-stage pattern with a predetermined length to be formed in a recording area of the second recording element in accordance with a second input gradation value in the second direction;
- a recording position in the second direction to be sequentially changed;
- and the first recording element and the second recording element to be sequentially switched to form a second-stage pattern to an (N+1)-th-stage pattern;
- and
- a test image forming unit that forms the test image in accordance with the input data acquired.
A test image forming method of forming a test image on a recording medium by relatively moving a recording head and the recording medium in a first direction and a second direction orthogonal to the first direction, the test image forming method comprising the steps of:
- acquiring input data in which, N representing an integer of 1 or more, a plurality of recording elements selected every N pieces in a projected recording element group of a plurality of recording elements provided in the recording head, projected in the first direction, is indicated as a first recording element and a recording element that is not selected as the first recording element is indicated as a second recording element, the input data allowing:
- a first-stage pattern with a predetermined length to be formed in a recording area of the second recording element in accordance with a second input gradation value in the second direction;
- a recording position in the second direction to be sequentially changed;
- and the first recording element and the second recording element to be sequentially switched to form a second-stage pattern to an (N+1)-th-stage pattern;
- and
- forming the test image in accordance with the input data acquired.
An abnormal recording element detection system comprising:
- a test image acquiring unit that acquires a test image created in accordance with input data or reading data on the test image, the input data allowing the test image to be formed on a recording medium by allowing a recording head and the recording medium to relatively move in a first direction and a second direction orthogonal to the first direction, in which input data, N representing an integer of 1 or more, a plurality of recording elements selected every N pieces in a projected recording element group of a plurality of recording elements provided in the recording head, is indicated as a first recording element projected in the first direction, and a recording element that is not selected as the first recording element is indicated as a second recording element, the input data allowing:
- a first-stage pattern with a predetermined length to be formed in a recording area of the second recording element in accordance with a second input gradation value in the second direction;
- a recording position in the second direction to be sequentially changed;
- and the first recording element and the second recording element to be sequentially switched to form a second-stage pattern to an (N+1)-th-stage pattern;
- and
- an analysis unit that analyzes the test image acquired to detect an abnormal recording element in the recording head.
An abnormal recording element detection method comprising the steps of:
- acquiring a test image created in accordance with input data or reading data on the test image, the input data allowing the test image to be formed on a recording medium by allowing a recording head and the recording medium to relatively move in a first direction and a second direction orthogonal to the first direction, in which input data, N representing an integer of 1 or more, a plurality of recording elements selected every N pieces in a projected recording element group of a plurality of recording elements provided in the recording head, projected in the first direction, is indicated as a first recording element and a recording element that is not selected as the first recording element is indicated as a second recording element, the input data allowing:
- a first-stage pattern with a predetermined length to be formed in a recording area of the second recording element in accordance with a second input gradation value in the second direction;
- a recording position in the second direction to be sequentially changed;
- and the first recording element and the second recording element to be sequentially switched to form a second-stage pattern to an (N+1)-th-stage pattern;
- and
- analyzing the test image acquired to detect an abnormal recording element in the recording head.
