Abstract:
1. An image processing apparatus for processing image data, the image processing apparatus comprising: an acquisition unit configured to acquire monochrome image data indicating a gradation value of grey line; a first conversion unit configured to convert the monochrome image data acquired by said acquisition unit into intermediate image data by using a first lookup table, wherein the first lookup table associates a gradation value of grey line with a coordinate value of a color space; an image processing unit configured to process the intermediate image data converted by said first conversion unit; and a second conversion unit configured to convert the intermediate image data processed by said image processing unit into ink material data for printing a monochrome image by using a second lookup table, wherein the second lookup table associates a coordinate value of the color space with the ink material data, wherein a combination of the gradation value and the ink material data is assigned to a coordinate of the color space, and wherein the first lookup table and the second lookup table are defined based on the color space.
