Abstract:
In an ink-jet printer, when a gray is expressed by mixing ink of a plurality of colors, there is a concentration in which a use amount of the ink is large. If the gray in an edge portion of a character has the concentration of the large ink use amount, a bleeding of the ink occurs and a thin portion of the character is sometimes damaged. If the gray in the character edge portion has the concentration of the large ink use amount, the gray in the character edge portion is changed to the white side by image correction, and the damage of the character thin portion caused due to the ink bleeding is prevented.
