    • A method of printing with an ink jet printer includes providing a printhead having a plurality of first nozzles with a first size and a plurality of second nozzles with a second size larger than the first size. The first nozzles and the second nozzles are alternatingly disposed in a vertical direction. Print data corresponding to first columns of pixel locations is provided. The print data includes for each pixel location in the first columns both a respective large dot print datum and a respective small dot print datum. One of the respective large dot print datum and the respective small dot print datum is printed at a first pixel location of the corresponding pixel locations in the first columns. Second columns of pixel locations interleaved with the first columns of pixel locations are provided. The other of the respective large dot print datum and the respective small dot print datum not printed in said first pixel location of the first columns is printed at a first pixel location of the second columns of pixel locations.

    • A method of printing on a print medium with an ink jet printer uses a first color ink, a second color ink and a black ink. An image area on the print medium has a plurality of pixel locations. Print image data indicate one of a presence and an absence of the first color ink, the second color ink and the black ink at the plurality of pixel locations. A subset of the print image data is defined. A determination is made as to whether the subset of print image data indicates 1) a presence of the first color ink and/or the second color ink within the subset and a presence of the black ink within the subset; 2) a presence of each of the first color ink and the second color ink within the subset at a same corresponding pixel location; and/or 3) a presence of the first color ink and/or the second color ink within the subset at a number of corresponding pixel locations exceeding a threshold value. The print medium is printed on in the image area at an interlace level which is dependent upon the determination.
    • 用喷墨打印机在打印介质上打印的方法使用第一颜色墨水,第二颜色墨水和黑色墨水。 打印介质上的图像区域具有多个像素位置。 打印图像数据指示多个像素位置处的第一颜色墨水,第二颜色墨水和黑色墨水的存在和不存在。 定义打印图像数据的一个子集。 确定打印图像数据的子集是否表示1)子集内的第一颜色墨水和/或第二颜色墨水的存在以及该子集内的黑色墨水的存在; 2)在相同对应的像素位置存在子集内的第一颜色墨水和第二颜色墨水中的每一个; 和/或3)在超过阈值的多个对应像素位置存在子集内的第一颜色墨水和/或第二颜色墨水。 打印介质以取决于确定的隔行扫描级别打印在图像区域中。

    • A method of printing a high resolution image with a printhead in a multi-pass printing mode includes subdividing the high resolution image into a plurality of low resolution sub-images; subdividing each low resolution sub-image into a plurality of low resolution swath portions; and allocating an amount of a memory for buffer storage, the amount being only sufficient to store data corresponding to less than two of the low resolution swath portions. The method also includes, for each low resolution swath portion: halftoning each low resolution swath portion to generate a corresponding halftoned low resolution swath portion, the halftoning of each low resolution swath portion of a particular low resolution sub-image being performed independently of halftoning the low resolution swath portions of other low resolution sub-images; storing the halftoned low resolution swath portion into the amount of the memory; and printing the halftoned low resolution swath portion.
    • 以多通打印模式打印打印头的高分辨率图像的方法包括将高分辨率图像细分为多个低分辨率子图像; 将每个低分辨率子图像细分成多个低分辨率条纹部分; 以及分配用于缓冲存储的存储器的量,该量仅足以存储对应于小于两个低分辨率条纹部分的数据。 该方法还包括:对于每个低分辨率条带部分:对每个低分辨率条纹部分进行半色调以产生相应的半色调低分辨率条纹部分,对于特定的低分辨率子图像的每个低分辨率条纹部分的半色调是独立于半色调 其他低分辨率子图像的低分辨率条纹部分; 将半色调低分辨率条纹部分存储到存储器的量中; 并打印半色调低分辨率条纹部分。
