Abstract
An ink jet printing apparatus that improves the visibility of a character and its background in different colors or of outline characters is provided. Specifically, outline character bold data is inverted and each of the pixels in the data is expanded to adjacent eight pixels. Then, the expanded outline character is processed into expanded inverted data. The logical AND of the inverted expanded data and K data on a background image is then calculated to generate K data with the outline character expanded. This results in an image with the outline character expanded. That is, the present invention enables characters with improved visibility and free from blurredness to be printed while preventing the adverse effect of bleeding on the outline character.
