A print density setting method for image-forming apparatuses is disclosed. The print density setting method for an image-forming apparatus capable of forming an image based on at least three or more colour data and black data comprises steps of, when the image is formed in monotone, setting a combination ratio of data for a composite black created based on a mixing of the three colours, to the data for the black colour; and setting print density of the image to be formed based on the black data in the set combination ratio. Such a print density setting method can vary the density of an image created according to user's taste, and, when a user wants to minimize the ink consumption amount, the user sets the consumption amounts of the colour ink and the black inks.
