摘要： An image having high quality is output, in which density unevenness due to a deflection in an ejecting direction is reduced, in an inkjet printer for forming an image by ejecting small droplets at a high frequency and high density. Thereby, in a mask pattern employed for multi-pass printing, a print permission rate of an ejection port positioned at the end of a ejection port array is set higher than those of ejection ports positioned at the other parts of the ejection port array. Thus, even if extremely small droplets are ejected at a high frequency and high-density, the generated density unevenness is reduced, and an image excellent in uniformity and having high definition can be output at a high speed.

摘要： An image is output, the image having high quality in which density unevenness due to an end-deviation is excellently reduced in all colors in forming an image with use of a bidirectional inkjet printing head provided with ejection port arrays of a plurality of colors for small droplets of ink. Thereby, distributions of print permission rates of mask patterns to be used in performing a multi-pass printing are made different from each other in accordance with a distance between the two ejection port arrays for the same kind of ink. Thus, the degree of the end-deviation depending on the distance between the two ejection port arrays can be suppressed for every ejection port array.
摘要翻译：输出图像，使用设置有多种颜色的弹出端口排列的双向喷墨打印头，在形成图像时，由于端部偏差而产生的浓度不均匀性的图像具有高质量，在所有颜色中均显着降低墨滴。因此，根据用于同一种类墨水的两个喷射口阵列之间的距离，使得在执行多遍打印中使用的掩模图案的打印许可率的分布彼此不同。因此，对于每个喷射口阵列，可以抑制取决于两个喷射口阵列之间的距离的端部偏差的程度。

摘要： The interference between the dot arrangement pattern used for binarizing an image and the mask pattern for processing the dot arrangement pattern can be reduced and the well dispersed dot arrangement can realized by using the mask pattern. Specifically, in creating the mask, repulsive potential between the mask and the plane of dots arrangement pattern is calculated. That is, when the arrangement of print permitting pixels in the mask is determined, repulsive potential between print permitting pixels and dots on the plane of the dot arrangement pattern is calculated and print permitting pixels are arranged on the position where energy is the lowest and most dispersed. This enables print permitting pixels to be well dispersed in overlapping of the dot arrangement pattern and the mask. Consequently, as to dots formed by mask-processing and each scanning, their number is not unequally high in a specific scanning and dots are well dispersed.

摘要： The print permitting ratios of the masks in the first to fourth passes of a C ink are respectively 6.2%, 37.5%, 37.5%, and 18.8%. On the other hand, the print permitting ratios of the masks in the first to fourth passes of an M ink are respectively 12.5%, 37.5%, 37.5%, and 12.5%. In this way, the respective masks are set such that a larger amount of the C ink is applied in a later pass as compared with the M ink. Thereby, it is possible to reduce an amount of the M ink to be applied later with respect to the C ink functioning to “reduce a permeation speed of an ink applied later by filling,” and it is possible to prevent a permeation speed from slowing down overall. As a result, it is possible to prevent the occurrence of beading due to a time to complete permeation becoming longer.
摘要翻译： C油墨的第一至第四道次的掩模的印刷许可比分别为6.2％，37.5％，37.5％和18.8％。另一方面，M墨水的第一至第四遍中的掩模的印刷许可比率分别为12.5％，37.5％，37.5％和12.5％。以这种方式，各个掩模被设置为使得与M墨水相比，稍后通过更大量的C墨水被施加。由此，可以减少相对于“降低通过填充涂敷的油墨的渗透速度”起作用的C油墨稍后施加的M油墨的量，并且可以防止渗透速度变慢整体下降。结果，可以防止由于完成渗透的时间变长而发生珠粒。
