摘要： For input image data ('A') before conversion, each pixel is converted into N (=3) parts. In this case, the three sub-pixels of data corresponding to a recording pixel (black pixel) are converted into recording sub-pixels on both sides of the three ('B'). This eliminates the density variation within a single pixel. Therefore, it is possible to reduce the dot spacing at slanted area, for example, and hence eliminate jaggies, providing a reproduced image easily recognized.

摘要翻译： 对于转换前的输入图像数据（'A'），每个像素都被转换为N（= 3）个部分。 在这种情况下，对应于记录像素（黑色像素）的三个子像素被转换为三个（'B'）两侧的记录子像素。 这消除了单个像素内的密度变化。 因此，例如可以减小倾斜区域处的点间距，从而消除锯齿，从而提供容易识别的再现图像。
