Description

また、本発明の第2の印刷制御装置は、
インクを吐出するための複数のノズルを有する印刷ヘッドを備え、前記印刷ヘッドにより印刷媒体上にドットを形成して印刷を行う印刷部に、異なるタイミングで形成される第1のドットと第2のドットとの間の形成位置のずれを調整するためのテストパターンを印刷させる印刷制御装置であって、
前記テストパターンは、所定の面積に所定の記録率でドットが形成されるパッチ状のパターンであり、ほぼ全般に亘って、略同数の第1のドットと第2のドットとが、ほぼ等しい分散性で混在して形成されるテストパターンであることを要旨とする。[0025]
Further, the second print control device of the present invention includes:
A print head having a plurality of nozzles for ejecting ink, wherein a first dot and a second dot which are formed at different timings are formed in a printing unit which forms dots on a print medium by the print head and performs printing. A print control device that prints a test pattern for adjusting a formation position deviation between dots and
The test pattern is a patch-like pattern in which dots are formed in a predetermined area at a predetermined recording rate, and substantially the same number of first dots and second dots are distributed over substantially the entire area. The gist of the present invention is that the test patterns are formed in a mixed manner.
【0026】
本発明で用いるテストパターンは、所定の面積に所定の記録率でドットが形成されるパッチ状のパターンであり、ほぼ全般に亘って、略同数の第1のドットと第2のドットとが、ほぼ等しい分散性で混在して形成されるテストパターンである。本発明者は、また、異なるタイミングで形成される第1のドットと第2のドットとが略同数、ほぼ等しい分散性で混在して形成されると、これらのドット間の形成位置がずれた場合に、ざらつきが目立ちやすいことを見出した。このようなテストパターンによってもドット間の形成位置の相対的なずれによる粒状性を判別しやすくし、インクの吐出タイミングを調整しやすくすることができる。この結果、ドットの形成位置を精度よく調整することができるので、印刷画質を向上することができる。なお、「ほぼ全般に亘って」とは、ごく一部の領域で分散性や割合に関する条件を満たしていなくてもよいことを意味している。また、「略同数の第1のドットと第2のドット」とは、第1のドットと第2のドットとが、厳密に同一数でなくてもよいことを意味している。[0026]
The test pattern used in the present invention is a patch-like pattern in which dots are formed at a predetermined recording rate in a predetermined area, and substantially the same number of first dots and second dots are formed over substantially the entire area. This is a test pattern formed by being mixed with substantially equal dispersibility. The present inventor has also found that, when the first dots and the second dots formed at different timings are formed in a mixed manner with substantially the same number and substantially the same dispersibility, the formation positions between these dots are shifted. In some cases, they found that the roughness was noticeable. Even with such a test pattern, it is possible to easily determine the granularity due to the relative shift of the formation position between dots, and to easily adjust the ink ejection timing. As a result, since the dot formation position can be adjusted with high accuracy, the print quality can be improved. Note that "almost all over" means that the condition regarding the dispersibility and the ratio need not be satisfied in a very small part of the region. Further, “ substantially the same number of first dots and second dots” means that the first dots and the second dots do not have to be exactly the same number.

また、本発明の第2の調整方法は、
インクを吐出するための複数のノズルを有する印刷ヘッドを備え、前記印刷ヘッドにより印刷媒体上にドットを形成して印刷を行う印刷部を用いて異なるタイミングで形成される第1のドットと第2のドットとの間の形成位置のずれを調整する調整方法であって、

Further, the second adjustment method of the present invention includes:
A print head having a plurality of nozzles for discharging ink, a first dot and a second dot formed at different timings by using a printing unit that forms dots on a print medium by the print head and performs printing. An adjustment method for adjusting the deviation of the formation position between the dots and

(B) selecting an optimal test pattern from the plurality of printed test patterns;
(C) setting a drive timing of the print head corresponding to the selected test pattern;
With
In the step (a), the test pattern is a patch-like pattern in which dots are formed in a predetermined area at a predetermined recording rate, and substantially the same number of the first dots and the second dots This is an adjustment method that is a test pattern in which dots are mixed and formed with substantially the same dispersibility.

この調整方法によっても、ドット間の形成位置の相対的なずれによる粒状性を判別しやすくし、インクの吐出タイミングを調整しやすくすることができる。この結果、ドットの形成位置を精度よく調整することができるので、印刷画質を向上することができる。[0035]
With this adjustment method, and help determine the graininess caused by relative shift of the formation position between dots, it is a child easily adjusting the ejection timing of the ink. As a result, since the dot formation position can be adjusted with high accuracy, the print quality can be improved.

また、図19、図20には第1のドットと第2とを規則的に配置したパターンを例示したが、これに限定されるものではない。図21は、不規則に配置された第1のドットおよび第2のドットを示す説明図である。○は第1のドットを示している。また、●は、第2のドットを示している。図21(a)に示したように、第1のドットと第2のドットとが、不規則に配置されていてもよい。破線で囲った,ごく一部の領域Aには、第1のドットが多く形成されているが、破線で囲った領域Bには、不規則にほぼ等しい分散性で混在している。また、図21(b)に示したように、記録率が徐々に変化していくように配置されていてもよい。このようなパターンも、略同数の第1のドットと第2のドットとが、ほぼ等しい分散性で混在して形成されているパターンに相当する。[0085]
Further, FIGS. 19 and 20 illustrate patterns in which the first dots and the second dots are regularly arranged, but the present invention is not limited to this. FIG. 21 is an explanatory diagram showing first and second dots arranged irregularly. ○ indicates the first dot. Also, ● indicates a second dot. As shown in FIG. 21A, the first dots and the second dots may be arranged irregularly. A large number of first dots are formed in a small part of the area A surrounded by a broken line, but are mixed irregularly in the area B surrounded by a broken line with almost the same dispersibility. Further, as shown in FIG. 21B, the recording rates may be arranged so as to gradually change. Such a pattern also corresponds to a pattern in which substantially the same number of first dots and second dots are mixed and formed with substantially the same dispersibility.
