Image processing apparatus, printing apparatus and image processing method with generation of binary data according to a correspondence relationship defined by a dot arrangement pattern
Abstract:
17-valued data of a pixel in a multi-valued image is divided into two divisions for a two-pass printing, obtaining the division data. Next, by using an index pattern where arrangements of the numerals of 1 to 16 are dispersed, each dot data of C, M and Y in the division data is arranged. First, six dot data of C are assigned to the respective minor pixels of the numerals of 1 to 6 in accordance with a value of C1=6. Next, four dot data of M are assigned to the respective minor pixels of the numerals of 7 to 10 in accordance with a value of M1=4. Further, one dot data of Y is assigned to the minor pixel of the numerals of 11 in accordance with a value of Y1=1.
Abstract(Chinese):

将多值图像中的像素的17值数据划分为两段用于双程打印，获得分割数据。 接下来，通过使用分散了数字1〜16的配置的索引图案，布置分割数据中的C，M和Y的每个点数据。 首先，根据C1 = 6的值将C的6个点数据分配给数字1〜6的各个次要像素。 接下来，根据M1 = 4的值将M的四个点数据分配给数字7〜10的各个次要像素。 此外，根据Y1 = 1的值将Y的一个点数据分配给数字11的次要像素。
