Claims (5)
元画像を構成する各画素の階調値を表す画像データに対してハーフトーン処理を行うことによって、前記印刷媒体上に形成されるべき印刷画像の各印刷画素へのドットの形成状態を決定するとともに、前記決定されたドットの形成状態を表すドットデータを生成するドットデータ生成部と、
同一色のインクを吐出する複数のノズルグループを備え、前記ドットデータに応じて前記複数のノズルグループからインクを吐出することによって前記各印刷画素にドットを形成して印刷画像を生成する印刷画像生成部と、
を備え、
前記印刷画像生成部は、前記複数のノズルグループの各々のドット形成対象となる各画素グループに形成されるドット群を、共通の印刷領域で相互に組み合わせることによって前記印刷画像を形成し、
前記ハーフトーン処理は、前記複数のドット群のいずれもが所定の特性を有するように前記ハーフトーンの条件が設定されている印刷装置。 A printing device for printing on a print medium,
A halftone process is performed on the image data representing the gradation value of each pixel constituting the original image, thereby determining a dot formation state on each print pixel of the print image to be formed on the print medium. A dot data generation unit that generates dot data representing the determined dot formation state, and
Print image generation that includes a plurality of nozzle groups that discharge ink of the same color, and generates dots by forming dots at the respective print pixels by discharging ink from the plurality of nozzle groups according to the dot data And
With
The print image generation unit forms the print image by combining dot groups formed in each pixel group that is a dot formation target of each of the plurality of nozzle groups with each other in a common print region,
In the halftone process, the halftone condition is set so that all of the plurality of dot groups have predetermined characteristics.
前記複数のノズルグループの各々は、副走査方向に偶数かつ一定のノズルピッチで配列された複数のノズルを有するとともに、前記複数のノズルグループ相互間で副走査方向に最も近接するノズルの副走査方向の間隔であるグループ間ピッチが奇数となるように副走査方向に配置されている印刷装置。 The printing apparatus according to claim 1,
Each of the plurality of nozzle groups has a plurality of nozzles arranged at an even and constant nozzle pitch in the sub-scanning direction, and the sub-scanning direction of the nozzle closest to the sub-scanning direction among the plurality of nozzle groups The printing apparatus is arranged in the sub-scanning direction so that the inter-group pitch, which is the interval between, is an odd number.
前記複数のノズルグループの各々は、副走査方向に偶数かつ一定のノズルピッチで配列された複数のノズルを有するとともに、前記複数のノズルグループ相互間で副走査方向に最も近接するノズルの副走査方向の間隔であるグループ間ピッチが前記ノズルピッチのＮ倍（Ｎは１以上の整数）となるように副走査方向に配置されている印刷装置。 The printing apparatus according to claim 1,
Each of the plurality of nozzle groups has a plurality of nozzles arranged at an even and constant nozzle pitch in the sub-scanning direction, and the sub-scanning direction of the nozzle closest to the sub-scanning direction among the plurality of nozzle groups The printing apparatus is arranged in the sub-scanning direction so that the inter-group pitch, which is an interval of N, is N times the nozzle pitch (N is an integer of 1 or more).
前記複数のノズルグループは、前記グループ間ピッチが前記ノズルピッチよりも大きくなるように配置されている印刷装置。 The printing apparatus according to claim 2 , wherein:
The printing apparatus in which the plurality of nozzle groups are arranged such that a pitch between the groups is larger than the nozzle pitch.
前記所定の特性は、ブルーノイズ特性とグリーンノイズ特性のいずれか一方である、印刷装置。 The printing apparatus according to any one of claims 1 to 4 ,
The printing apparatus, wherein the predetermined characteristic is one of a blue noise characteristic and a green noise characteristic.
