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.
請求項1記載の印刷装置であって、
