摘要： A dark color (for example, cyan) ink dot formed by preliminary ejection can be made less noticeable, and the influence on the printing quality can be reduced, even in a case where the dark color ink is preliminarily ejected onto a light color (for example, yellow) image area. For this purpose, in a case where the dark color ink is preliminarily ejected onto the image area of high lightness, the amount of the ink applied for printing the area is reduced. For example, in a case where a cyan ink is preliminarily ejected onto an area to be formed of yellow dots, a piece of data for forming the yellow dot in the preliminary ejection position is deleted. This reduces an overlapping area of the yellow area and the ink dot formed by the preliminary ejection, and thus makes the ink dot formed by the preliminary ejection less noticeable.
摘要翻译： 通过初步喷射形成的深色（例如青色）墨点可以变得不太明显，即使在深色墨水被预先喷射到浅色的情况下也可以降低对打印质量的影响（对于 示例，黄色）图像区域。 为此，在深色油墨预先喷射到高亮度的图像区域的情况下，用于打印该区域的油墨的量减少。 例如，在将青色墨预先喷射到要由黄点形成的区域的情况下，删除在预喷射位置形成黄点的数据。 这样可以减少黄色区域和通过预喷射形成的墨点的重叠区域，从而使由初步喷射形成的墨点不太明显。
