Abstract:
(EN) Provided are an image recording device, a dither mask, and an image recording method that can suppress generation of density unevenness without reducing productivity. The image recording device repeatedly performs: a main scanning operation in which recording is performed by moving a recording head having a row of nozzles in a main scanning direction relative to a recording medium; and a sub scanning operation in which the recording medium is moved in a sub scanning direction relative to the recording head. In the image recording device, the nozzle ejection rate of each nozzle is controlled using a dither mask. A threshold value of a dither mask is set such that the sum of the total sum of the nozzle ejection rates of corresponding nozzles of nozzle groups used in recording of the first half of a scanning operation for recording scanning bands and the total sum of the nozzle ejection rates of the corresponding nozzles of the nozzle groups used in the recording of the second half of the scanning operation is a constant value that falls within a stipulated permitted range for at least part of the recording duty range.
(FR) L'invention concerne un dispositif d'enregistrement d'image, un masque de tramage et un procédé d'enregistrement d'image qui peuvent supprimer la génération d'une irrégularité de densité sans réduire la productivité. Le dispositif d'enregistrement d'image effectue de manière répétée : une opération de balayage principal dans laquelle un enregistrement est effectué en déplaçant une tête d'enregistrement comportant une rangée de buses dans une direction de balayage principale par rapport à un support d'enregistrement ; et une opération de sous-balayage dans laquelle le support d'enregistrement est déplacé dans une direction de sous-balayage par rapport à la tête d'enregistrement. Dans le dispositif d'enregistrement d'image, le taux d'éjection de buse de chaque buse est commandé à l'aide d'un masque de tramage. Une valeur de seuil d'un masque de tramage est réglée de telle sorte que la somme de la somme totale des taux d'éjection de buse de buses correspondantes de groupes de buses utilisés dans l'enregistrement de la première moitié d'une opération de balayage pour enregistrer des bandes de balayage et la somme totale des taux d'éjection de buse des buses correspondantes des groupes de buses utilisés dans l'enregistrement de la seconde moitié de l'opération de balayage est une valeur constante qui rentre dans une plage autorisée stipulée pour au moins une partie de la plage de service d'enregistrement.
(JA) 生産性を落とすことなく、濃度ムラの発生を抑制することができる画像記録装置、ディザマスク及び画像記録方法を提供する。ノズル列を有する記録ヘッドを記録媒体に対して主走査方向に相対移動させで記録を行う主走査動作と、記録媒体を記録ヘッドに対して副走査方向に相対移動させる副走査動作とを繰り返す画像記録装置において、各ノズルのノズル吐出率をディザマスクにより制御する。ディザマスクは、少なくとも一部の記録デューティの範囲について、各走査バンドを記録する前半走査の記録に用いられる各ノズル群の対応するノズル同士のノズル吐出率の総和と、後半走査の記録に用いられる各ノズル群の対応するノズル同士のノズル吐出率の総和の和が、規定の許容範囲に収まる一定の値になる閾値の設定がなされている。
