    Abstract: The present invention reduce the granularity of the dots for the entire density range by optimally setting formation amounts of a low-density dot and of a high-density dot per unit area. For this purpose, the formatior amounts of the low-density dot and of the high-density dot in accordance with the density level are decided in such a way that as the density level rises, the formation amount of the low-density dot is gradually increased up to a first peak amount (200 %) and, after reaching the first peak, gradually decreased, and in a range of density levels higher than a predetermined density level at which the low-density dot is formed to a specified amount (200 %), as the density level rises, the formation amount of the high-density dot is gradually increased up to a second peak amount (100 %) smaller than the first peak amount.

    Abstract: An apparatus and method is provided to enable high speed printing of an image with high resolution while suppressing degradation of image quality due to white stripes and density variations. In an ink jet printing apparatus using a multipass printing system, one and the same scan print area (E) is divided at a predetermined pitch and the printing duties of the divided areas (e1) or (e2) determined by the thinning out mask pattern are set to different values. Of the same scan print area (E) formed by a plurality of the main scans, the divided areas corresponding to the ends of the print head (H1001) have their printing duties set smaller than those of the divided areas (e1) or (e2) on the inner side of the ends of the print head (H1001).

    Abstract: In a recording apparatus for recording on a recording medium by using a plurality of recording heads arrange at a predetermined interval in a scan direction, said recording heads are caused to scan corresponding divided recording areas, said recording heads are caused to make the record by sharing the corresponding divided recording areas when said recording heads are caused to scan the divided recording areas, and record signals to be inputted to the recording heads corresponding to the divided recording areas to be recorded in the shared manner, are independently corrected for each of the divided recording areas. As a result, the occurrence of the density difference between divided areas is prevented.

    Abstract: REIVINDICACIONES 1. Método de impresión que utiliza un cabezal de impresión (H1000) sobre el que se disponen una serie de aberturas de expulsión (2001) para expulsar tintas en una dirección de disposición (D, Y) y separadas mediante una anchura de disposición (PASO), comprendiendo dicho método las etapas de: desplazamiento de dicho cabezal de impresión para escanear en las diferentes direcciones (X) hacia adelante y hacia atrás de la dirección de disposición (D, Y) de dicha serie de aberturas de expulsión; transportar relativamente un soporte de impresión (1907) en la dirección (Y) perpendicular a la dirección de escaneado (X) unas cantidades menores que la anchura de disposición de dicha serie de aberturas de expulsión; y formar una imagen sobre el soporte de impresión mediante los escaneados hacia adelante y hacia atrás en tiempos diferentes según las disposiciones de píxeles en una relación complementaria a la misma área de imagen; y caracterizado por hacer una proporción de la cantidadde impresión de datos en un primer escaneado de dichos diferentes escaneados hacia adelante y hacia atrás del total de la cantidad de impresión de datos para dicha misma área de imagen menor que una proporción de cantidad de impresión de datos en un segundo escaneado, y hacer la suma de las proporciones de recubrimiento de dicho soporte de impresión formando puntos en dicho primer escaneado y dicho segundo escaneado mayor que el 50%, durante la formación de dicha imagen.

    Abstract: In a recording apparatus for recording on a recording medium by a plurality of recording heads, a scan unit has a carriage capable of mounting the recording heads at a predetermined interval and causes the recording heads to scan corresponding divided recording areas. A record control unit causes the recording heads to conduct a first record mode to record an area of a first recording width in a direction of scan by shared recording by the recording heads of the corresponding recording areas and a second record mode to record an area of a second recording width smaller than the recording width of the first recording width by causing at least one of the recording heads to record in the corresponding divided recording area when the corresponding divided recording areas are scanned. A distance between two recording apparatus mounted at outermost positions in the arrangement of the recording heads on the carriage is not larger than a difference between the first recording width and the second recording width.
